MLCCs added to flex mitigation portfolio

28 May 2008 Passive Components

Kemet has launched its FE-CAP product line to complement its flex mitigation portfolio. The FE-CAP is a surface mount multilayer ceramic capacitor (MLCC) which utilises a floating internal electrode design, wherein the electrodes are configured to form multiple capacitors in series within a single MLCC package. This not only yields improved voltage and ESD performance over standard designs, but also mitigates the risk of low-IR or short-circuit failures that can occur due to board flex.

The FE-CAP is being offered in case sizes ranging from EIA 0402 to EIA 1812 with rated voltages ranging from 6,3 to 250 V d.c. Combined with the stability of an X7R dielectric, the FE-CAP offers a flex-robust solution at low- to mid-range capacitance values and an operating temperature range of -55°C to +125°C with zero bias capacitance shift limited to ±15% over that range. Capacitance tolerances offered include J (±5%), K (±10%) and M (±20%).

These components are widely used in critical application where mechanical stress is a concern. When flexed to mechanical failure the floating electrode design of the FE-CAP eliminates the current path between positive and negative poles. Absence of this current path reduces the probability of a short-circuit condition.

All FE-CAP products meet the requirements of the Automotive Electronics Council's AEC-Q200-Rev C and come with 100% pure matte, tin-plated terminations for superior solderability.
