B32620, B32621 High pulse (stacked) 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/(cid:4)0.5 mm from capacitor body or seating plane Evaluation criteria: Wetting of wire surface by new solder ≥90%, Visual inspection free-flowing solder 1.2 Resistance to soldering heat Resistance to soldering heat is tested to IEC 60068-2-20:2008, test Tb, method 1.

Long exposure to temperatures above this type-related temperature limit max 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 PleasereadCautionsandwarningsand Page21of30 Importantnotesattheendofthisdocument.

B32620, B32621 High pulse (stacked) The overheating associated with some of these factors can usually be reduced by suitable coun- termeasures. For example, if a pre-heating step cannot be avoided, an additional or reinforced cooling process may possibly have to be included. EPCOS recommendations As a reference, the recommended wave soldering profile for our film capacitors is as follows: PleasereadCautionsandwarningsand Page22of30 Importantnotesattheendofthisdocument.

B32620, B32621 High pulse (stacked) Body temperature should follow the description below: MKP capacitor During pre-heating: T ≤110 °C p During soldering: T ≤120 °C, t ≤45 s s s MKT capacitor During pre-heating: T ≤125 °C p During soldering: T ≤160 °C, t ≤45 s s 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 (T ) must be ≤120 °C. s 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 mea- sures are recommended: pre-heating to not more than 110 °C in the preheater phase rapid cooling after soldering Please refer to EPCOS Film Capacitor Data Book in case more details are needed. PleasereadCautionsandwarningsand Page23of30 Importantnotesattheendofthisdocument.

B32620, B32621 High pulse (stacked) 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 EPCOS. Please note that the standards referred to in this publication may have been revised in the meantime. The table below summarizes the safety instructions that must always be observed. A detailed de- scription can be found in the relevant sections of the chapters "General technical information" and "Mounting guidelines".

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 re- quirements 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, EPCOS is either unfamiliar with individual customer applications or less familiar with them than the customers themselves. For these reasons, it is always ultimately incum- bent on the customer to check and decide whether an EPCOS product with the properties de- scribed 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 Ma- terial Data Sheets on the Internet (www.epcos.com/material). Should you have any more de- tailed 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 fore- going for customer-specific products. 6. Unless otherwise agreed in individual contracts, all orders are subject to the current ver- sion of the "General Terms of Delivery for Products and Services in the Electrical In- dustry" published by the German Electrical and Electronics Industry Association (ZVEI).

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.
