New SMT MLCC Capacitors with SnPb Finish

Introduces by Vishay for Aerospace Applications..

Vishay Intertechnology introduces a new series of surface-mount multilayer ceramic chip capacitors (MLCCs) with a lead (Pb)-bearing termination finish suitable for aerospace applications requiring tin whisker mitigation.

The new VJ….32 lead-bearing finish series SMD MLCCs offer termination finishes with a minimum lead (Pb) content of 4 % to mitigate tin whisker formation.

Previously, the option for lead (Pb)-bearing termination finishes was reserved for more expensive Hi-Rel devices. The VJ….32 Lead-Bearing Finish Series provides designers with a cost-effective alternative for aerospace systems in which tin whiskers must be avoided but space-level reliability isn’t required. The MLCC SnPb capacitors are qualified according to AEC-Q200 to provide designers with Automotive Grade reliability.
