## **Pulse handling capability** 

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

"k0" represents the maximum permissible pulse characteristic of the waveform applied to the capacitor, expressed in V[2] /μs. 

## _Note:_ 

_The values of dV/dt and k0 provided below must not be exceeded in order to avoid damaging the capacitor._ 

_These parameters are given for isolated pulses in such a way that the heat generated by one pulse will be completely dissipated before applying the next pulse._ 

_For a train of pulses, please refer to the curves of permissible AC voltage-current versus frequency._

## **Mounting guidelines** 

## **1 Soldering** 

## **1.1 Solderability of leads** 

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

Before a solderability test is carried out, terminals are subjected to accelerated ageing (to IEC 60068-2-2, 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.

## **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 

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: 

Please read _Cautions and warnings_ and _Important notes_ at the end of this document. 

Page 14 of 22 

## **B32591 ... B32594** ~~EE~~ **General purpose (stacked/wound)** 

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 

Please refer to our Film Capacitors Data Book in case more details are needed.

## **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 lifesaving 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.
