NOTE 1 An overvoltage equal to 1.5 ∙ VR for 30 ms is permitted 1000 times during the life of the capacitor. 

The amplitudes of the overvoltages that may be tolerated without significant reduction in the life time of the capacitor depend on their duration, the number of application and the capacitor temperature. 

In addition these values assume that the overvoltages may appear when the internal temperature of the capacitor is less than 0 °C but within the temperature category. 

NOTE 2 The average applied voltage must not be higher than the specified voltage. 

## **Pulse handling capability** 

"dV/dt" represents the maximum permissible voltage change per unit of time for non-sinusoidal voltages, expressed in V/μs. 

Note: 

The values of dV/dt provided below must not be exceeded in order to avoid damaging the capacitor.

The equivalent heat coefficient **"G (mW/ºC)"** is given for measuring the temperature on the lateral surface of the plastic box as Figure 1 shows. By using a thermocouple and avoiding effect of radiation and convection the temperature measured during operation conditions should be a result of the dissipated power divided by the equivalent heat coefficient.

## **Self Heating by power dissipation & equivalent heat coefficient** 

The IRMS and consequently the power dissipation must be limited during operation in order to not exceed the maximum limit of T allowed for this series. Tmax given for this series is equal or lower than 20 °C at rated temperature (70 °C), for higher ambient temperatures Tmax (T) will have the same derating factor than IRMS versus temperature and then an equivalent derating as per: ambient temperatures Tmax (T) will have the same derating factor than IRMS versus temperature and then an equivalent derating as per: 

**==> picture [126 x 10] intentionally omitted <==**

For any particular IRMS the T may be calculated by: 

**==> picture [118 x 9] intentionally omitted <==**

Where T (°C) is the difference between the temperature measured on the box (see Figure 1) and the ambient temperature when capacitor is working during normal operation; 

**==> picture [104 x 10] intentionally omitted <==**

It represents the increasing of temperature provoked by the IRMS during operation. G (mW/°C) is the equivalent heat coefficient described above and Pdis (mW) is the dissipated power defined by: 

**==> picture [147 x 10] intentionally omitted <==**

## **Example for thermal calculation:** 

We will take as reference B32778G0306K (30 µF/1100 V) type for thermal calculation. Considering the following load and capacitor characteristics: 

IRMS : 12 ARMS at 20 kHz TA: 85 °C 30 × 45 × 57.5 box G (mW/°C): 125 

Then we have to find the ESRtyp at 20 kHz what is approx . 8.2 m. 

So according to: 

**==> picture [144 x 10] intentionally omitted <==**

we have the following: 

Pdis (mW) = 8.2 mΩ × 12 ARMS[2] = 1181 mW 

and as per: 

T (°C) = Pdis (mW) / G (mW/°C) 

we have the following: 

T (°C) = 1181 (mW) / 125 (mW/°C) = 9.5 °C. 

What is below of the 

Tmax (85 °C) = (Factor)[2] × T (70 °C) = (0.7)[2] × 20 °C = 9.8 °C. On the other hand we may confirm that max IRMS at 20 kHz at 70 °C = 17.5 ARMS 

And then max IRMS for 85 °C of ambient temperature is defined as follows: 

IRMS (85 °C) = Factor × IRMS (70 °C) = 0.7 × 17.5 ARMS = 12.25 ARMS. What confirms once again that IRMS (12 ARMS at 20 kHz) is below the max specified for such frequency and ambient temperature.

## **Mounting guidelines** 

## **1 Soldering** 

## **1.1 Solderability of leads** 

The solderability of terminal leads is tested to IEC 60068-2-20:2008, test Ta, method 1. 

Before a solderability test is carried out, terminals are subjected to accelerated ageing (to IEC 60068-2-2:2007, test Ba: 4 h exposure to dry heat at 155 C). Since the ageing temperature is far higher than the upper category temperature of the capacitors, the terminal wires should be cut off from the capacitor before the ageing procedure to prevent the solderability being impaired by the products of any capacitor decomposition that might occur. 

|Solder bath temperature|235 ±5 °C|

|Soldering time|2.0 ±0.5 s|
|Immersion depth|2.0 +0/–0.5 mm from capacitor body or seating plane|

## **1.3 General notes on soldering** 

Permissible heat exposure loads on film capacitors are primarily characterized by the upper category temperature Tmax. Long exposure to temperatures above this type-related temperature limit can lead to changes in the plastic dielectric and thus change irreversibly a capacitor's electrical characteristics. For short exposures (as in practical soldering processes) the heat load (and thus the possible effects on a capacitor) will also depend on other factors like: 

Pre-heating temperature and time Forced cooling immediately after soldering Terminal characteristics: 

diameter, length, thermal resistance, special configurations (e.g. crimping) Height of capacitor above solder bath Shadowing by neighboring components Additional heating due to heat dissipation by neighboring components Use of solder-resist coatings

**Metallized polypropylene film capacitors (MKP) MKP DC link – high density series up to 480 μF** 

**B32774 ... B32778** 

The overheating associated with some of these factors can usually be reduced by suitable countermeasures. For example, if a pre-heating step cannot be avoided, an additional or reinforced cooling process may possibly have to be included. 

## **Recommendations** 

As a reference, the recommended wave soldering profile for our film capacitors is as follows:

**42** 3/23 

**Metallized polypropylene film capacitors (MKP) MKP DC link – high density series up to 480 μF** 

**B32774 ... B32778** 

Body temperature should follow the description below: 

MKP capacitor During pre-heating: Tp 110 C During soldering: Ts 120 C, ts 45 s MKT capacitor During pre-heating: Tp 125 °C During soldering: Ts 160 °C, ts 45 s 

When SMD components are used together with leaded ones, the film capacitors should not pass into the SMD adhesive curing oven. The leaded components should be assembled after the SMD curing step. 

Leaded film capacitors are not suitable for reflow soldering. 

In order to ensure proper conditions for manual or selective soldering, the body temperature of the capacitor (Ts) must be 120 C. 

One recommended condition for manual soldering is that the tip of the soldering iron should be <360 C and the soldering contact time should be no longer than 3 seconds. 

For uncoated MKT capacitors with lead spacings 10 mm (B32560/B32561) the following measures are recommended: 

pre-heating to not more than 110 C in the preheater phase rapid cooling after soldering

## **Cautions and warnings** 

- Do not exceed the upper category temperature (UCT). 

- Do not apply any mechanical stress to the capacitor terminals. 

- Avoid any compressive, tensile or flexural stress. 

- Do not move the capacitor after it has been soldered to the PC board. 

- Do not pick up the PC board by the soldered capacitor. 

- Do not place the capacitor on a PC board whose PTH hole spacing differs from the specified lead spacing. 

- Do not exceed the specified time or temperature limits during soldering. 

- Avoid external energy inputs, such as fire or electricity. 

- Avoid overload of the capacitors. 

- Consult us if application is with severe temperature and humidity condition. 

- There are no serviceable or repairable parts inside the capacitor. Opening the capacitor or any attempts to open or repair the capacitor will void the warranty and liability of TDK Electronics.

## **Display of ordering codes for TDK Electronics products** 

The ordering code for one and the same product can be represented differently in data sheets, data books, other publications, on the company website, or in order-related documents such as shipping notes, order confirmations and product labels. The varying representations of the ordering codes are due to different processes employed and do not affect the specifications of the respective products. 

Detailed information can be found on the Internet under www.tdk-electronics.tdk.com/orderingcodes. 

## **Correlation of data sheet values and modelling tool outputs** 

Data sheet values and results of design tools may deviate as they have not been derived in the same context. 

While data sheets show individual parameter statements without considering a possible dependency to other parameters. Tools model  a complete given scenario as input and processed inside the tool. Furthermore as we constantly strive to improve our models, the results of tools can change over time and be a non-binding indication only.

## **Important notes** 

The following applies to all products named in this publication: 

1. Some parts of this publication contain **statements about the suitability of our products for certain areas of application** . These statements are based on our knowledge of typical requirements that are often placed on our products in the areas of application concerned. We nevertheless expressly point out **that such statements cannot be regarded as binding statements about the suitability of our products for a particular customer application.** As a rule, we are either unfamiliar with individual customer applications or less familiar with them than the customers themselves. For these reasons, it is always ultimately incumbent on the customer to check and decide whether a product with the properties described in the product specification is suitable for use in a particular customer application. 

2. We also point out that **in individual cases, a malfunction of electronic components or failure before the end of their usual service life cannot be completely ruled out in the current state of the art, even if they are operated as specified.** In customer applications requiring a very high level of operational safety and especially in customer applications in which the malfunction or failure of an electronic component could endanger human life or health (e.g. in accident prevention or life-saving systems), it must therefore be ensured by means of suitable design of the customer application or other action taken by the customer (e.g. installation of protective circuitry or redundancy) that no injury or damage is sustained by third parties in the event of malfunction or failure of an electronic component. 

3. **The warnings, cautions and product-specific notes must be observed** . 

4. In order to satisfy certain technical requirements, **some of the products described in this publication may contain substances subject to restrictions in certain jurisdictions (e.g. because they are classed as hazardous)** . Useful information on this will be found in our Material Data Sheets on the Internet (www.tdk-electronics.tdk.com/material). Should you have any more detailed questions, please contact our sales offices. 

5. We constantly strive to improve our products. Consequently, **the products described in this publication may change from time to time** . The same is true of the corresponding product specifications. Please check therefore to what extent product descriptions and specifications contained in this publication are still applicable before or when you place an order. We also **reserve the right to discontinue production and delivery of products** . Consequently, we cannot guarantee that all products named in this publication will always be available. The aforementioned does not apply in the case of individual agreements deviating from the foregoing for customer-specific products. 

6. Unless otherwise agreed in individual contracts, **all orders are subject to our General Terms and Conditions of Supply** .

## **Important notes** 

7. **Our manufacturing sites serving the automotive business apply the IATF 16949 standard** . The IATF certifications confirm our compliance with requirements regarding the quality management system in the automotive industry. Referring to customer requirements and customer specific requirements (“CSR”) TDK always has and will continue to have the policy of respecting individual agreements. Even if IATF 16949 may appear to support the acceptance of unilateral requirements, we hereby like to emphasize that **only requirements mutually agreed upon can and will be implemented in our Quality Management System.** For clarification purposes we like to point out that obligations from IATF 16949 shall only become legally binding if individually agreed upon. 

8. The trade names EPCOS, CarXield, CeraCharge, CeraDiode, CeraLink, CeraPad, CeraPlas, CSMP,   CTVS, DeltaCap, DigiSiMic, ExoCore, FilterCap, FormFit, InsuGate, LeaXield, MiniBlue, MiniCell, MKD, MKK, ModCap, MotorCap, PCC, PhaseCap, PhaseCube, PhaseMod, PhiCap, PowerHap, PQSine, PQvar, SIFERRIT, SIFI, SIKOREL, SilverCap, SIMDAD, SiMic, SIMID, SineFormer, SIOV, ThermoFuse, WindCap, XieldCap are **trademarks registered or pending** in Europe and in other countries.
