## **Restrictions** 

**VR** : Maximum operating peak voltage of either polarity but of a non-reversing waveform, for which the capacitor has been designed for continuous operation. 

## **ûAC, max** ≤ **0.2 • VR** 

|**ûAC, maxAC, max max**≤**0.2 • VRR**|||
|---|---|---|
|**Overvoltage**|**Maximum duration within**<br>**one day**|**Observation**|
|1.1 • VR|30 % of on-load duration|System regulation|
|1.15 • VR|30 min|System regulation|
|1.2 • VR|5 min|System regulation|
|1.3 • VR|1 min|System regulation|



## 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/ms. 

Note: 

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

## **Soldering** 

## **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|

## **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

**Film Capacitors Metallized Polypropylene Film Capacitors (MKP)** 

**B32320I* B32320I** 

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: 

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.

~~LT~~ **Film Capacitors B32320I* Metallized Polypropylene Film Capacitors (MKP) B32320I** 

For uncoated MKT capacitors with lead spacings ≤10 mm, the following measures are recommended: 

- pre-heating to not more than 110 °C in the preheater phase 

- rapid cooling after soldering 

## **Cleaning** 

To determine whether the following solvents, often used to remove flux residues and other substances, are suitable for the capacitors described, refer to the table below: 

|Type|Ethanol, isopropanol, n-propanol|n-propanol-water mixtures, water with<br>surface tension-reducing tensides (neutral)|
|---|---|---|
|MKT<br>(uncoated)|Suitable|Unsuitable|
|MKT, MKP, MFP<br>(coated/boxed)||Suitable|



Even when suitable solvents are used, a reversible change of the electrical characteristics may occur in uncoated capacitors immediately after they are washed. Thus it is always recommended to dry the components (e.g. 4 h at 70 °C) before they are subjected to subsequent electrical testing. 

## **Caution:** 

Consult us first if you wish to use new solvents! 

## **Embedding of capacitors in finished assemblies** 

In many applications, finished circuit assemblies are embedded in plastic resins. In this case, both chemical and thermal influences of the embedding ("potting") and curing processes must be taken into account. 

Our experience has shown that the following potting materials can be recommended: non-flexible epoxy resins with acid-anhydride hardeners; chemically inert, non-conducting fillers; maximum curing temperature of 100 °C. 

## **Caution:** 

Consult us first if you wish to embed uncoated types! 

## **Marking** 

## **Capacitor markings** 

Depending on the capacitor size, the markings are positioned either on the side and/or the top of the component. The coded forms specified in IEC 60062:2004 are used to indicate the rated capacitance, capacitance tolerance and date of manufacture. 

The lot number (production batch number) ensures unique identification of a particular capacitor and allows, together with the date of manufacture, exact assignment to the process data of the entire production run (traceability).

## **Marking types** 

The capacitors may have either an ink-jet marking or a laser marking. The main advantage of laser marking is that it cannot be removed by solvents, which ensures the reliable identification of the capacitor. Moreover, because the laser marking process reduces the amount of chemicals used, it is an environmentally friendly marking solution.

~~LT~~ **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)** .
