Features

Two series-connected ceramic capacitors in a

single component

The MLSC thus satisfies the requirements of the

automobile manufacturers for applications on the

battery / generator (e.g. clamp 30 or clamp 15)

in a single component.

Reduction of the effects of a

bending fracture

placement fracture

solder-shock crack

thanks to a lower probability of a short circuit.

Evaluation criteria: Insulation resistance >10 k after the following treatment

bending until crack

humidity tests (85

°C/85% RH, rated voltage), 14 days

The breakdown voltage of MLSCs in the case of a typical bending crack is still greater than

five times the rated voltage.

Both undamaged and cracked MLSCs are capable of fulfilling the requirements to

ISO 7637 for 12 V automotive power systems, including load-dump and jump-start

requirements (24 V/1 h and 36 V/1 h).

Applications

Automobile electronics

for direct connection to the car battery or generator

at positions with “stranding potential”

as RF filters in small motors (e.g. electrically operated windows)

Power electronics (e.g. DC/DC converters)

Smoothing capacitors (e.g. on the rechargeable battery in mobile equipment)

Cautions

A short circuit cannot be completely excluded. The use of MLSCs does not therefore result in

100% fail-safe operation, but in the event of a crack the probability of a short circuit can be

greatly reduced.

In the event of an untypical (bending) crack formation (e. g. double-sided crack or extreme

mounting crack) and other mechanical or thermal damage to the capacitor, the capacitor may

have a low ohmic state.
