Multilayer ceramic capacitor MLSC series
B37941X MLSC 0805, 50 V and 100 V
Description
The MLSC series was designed for applications directly linked to a power source / voltage source (e.g. battery, clamp 30 in automotive applications) and safety relevant application without (integrated) current limitation.
Features
The MLSC (Multi Layer Serial Ceramic Capacitor) consists of two serial connected capacitors in one component Due to the special design the probability of a short circuit is much reduced - in case of a bending crack - in many cases of an assembling crack - in many cases of a solder shock crack The MLSC meets the requirements of automotive manufacturers for a (redundant) serial connection of two capacitors, if the application is directly connected to the battery, in one component. Reduced number of components leads to - increased reliability - place saving on the PCB - reduced assembling time The MLSC is based on established MLCC technology, but with more robust design. This MLCC technology offers highest reliability (ppb-rate) and long term field experience. The MLSC offers high reliability due to more stringent process control and end of line testing, which enables the achievement of a 10 ppb level for the application failure rate (measure: 0 mileage and field), see chapter ppb - Level Assurance System page 12. The MLSC meets AEC-Q200 requirements, see pages 7 - 11. The specified bending strength is 2 mm according to piezo electric method (I measurement) The MLSC is suitable for applications with temperature requirements up to 150 C with respect to the voltage derating and short term temperature peaks up to 175 C without load, see chapter High Temperature Application page 3. The MLSC is lead free in terms of RoHS. Nickel barrier termination BME technology The MLSC offers a selected range of capacitance in case size 0805 (rated voltage 50 V and 100 V).

Applications
Applications directly linked to a power source / voltage source and safety relevant application without (integrated) current limitation. Some examples: Automotive electronics (e.g. clamp 30, RF filter in small power motors, security control systems or drive and engine control units) Power electronics (e.g. DC/DC converter) Mobile devices with battery / accumulator (e.g. filter at charging set)
Differentiation to Standard Series
Special design of two capacitors serial connected Usage of the ppb - Level Assurance System Statistical methods (e.g. six-sigma) for design and process control Periodical testing for solder shock at 360 C followed by HALT test Periodical testing for bending strength by piezo-electric method Usage of the Weibull method as statistical tool for data analysis Dynamic test limits for at 100% electrical inspection 100% automatic optical inspection - AOI An application failure rate (measure: 0 mileage and filed) of 10ppb is achievable. Suitable for High Temperature Applications with respect to voltage derating
High Temperature Application:
The maximum application temperature might increase 125 C for the listed MLSC with respect to the following voltage derating (given in % of the rated voltage). A further reduction of the applied voltage is recommended as the reliability of MLSC follows an Arrhenius law. In addition a short time temperature increase up to 175 C without load is allowed.

MLSC design
The MLSC is characterised by a serial capacitor design (see pictures below). The design of the components reduces drastically the probability of short circuits in case of flex cracks. Crack formation in a standard MLCC:

KKE0383-H-E
KKE0387-F-E
Features Two capacitors are serial connected in one multilayer ceramic capacitor Reduced probability of shorts after flex cracking Evaluation criteria: Insulation resistance >10 k after the following treatment 1. Bending till flex crack 2. Humidity tests (85 C/85% RH, rated voltage), 14 days The breakdown voltage of MLSC in case of typical flex cracking is still higher than 5 times the rated voltage. Both the un-damaged as well as flex cracked MLSC is capable to fulfil the requirements per ISO 7637 for 12V board systems, including load-dump and jump-start requirements (24V/1h and 36V/1h). BME technology
U Caution
It is not possible to prevent a short circuits for 100%. That means the use of MLSC does not result in 100% failure safe mode, but in case of a crack the probability of a short cut can be much reduced. In case of a not typical (bending) crack formation (e.g. double sided crack or extreme assembling crack) and other mechanical or thermal damage to the capacitor a low ohmic state of the capacitor will be the result.

Further information
Please see General Technical Information at www.epcos.com/ceramic_capacitors or the data book "Multilayer Ceramic Capacitors" for further information on: Soldering directions Taping and packing Surface mounting instructions Effects of mechanical stress
Cautions
Derating: A "state of the art" application design is essential to achieve failures rates at ppb level. Do not use designs based on 100% of specified rated values. AC applications may damage MLSC on a much lower level than DC voltage due to power dissipation losses. Mechanical stress - Please note EPCOS "General Technical Information", "Surface mounting instructions" and information about the effect of mechanical stress. ESD - EPCOS recommends the use of varistors. Further processing - care must be taken using moulding processes. Combined stresses - the total stress (e.g. DC voltage, AC ripple, pulses and temperature) has to be taken into account to estimate reliability of MLSC.

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, EPCOS is 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 an EPCOS 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 passive 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 a passive 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 a passive 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.epcos.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.
6. Unless otherwise agreed in individual contracts, all orders are subject to the current version of
the "General Terms of Delivery for Products and Services in the Electrical Industry" published by the German Electrical and Electronics Industry Association (ZVEI). 7.
