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.
