KEMET MLCC High Voltage Floating Electrode Design

KEMET Floating Electrode High Voltage with Standard (FE-CAP) or Flexible Termination Capacitors (FF-CAP) combines two existing KEMET technologies– floating electrode and flexible termination. The floating electrode component utilizes a cascading / serial electrode design configured to form multiple capacitors in series within a single monolithic structure. This unique configuration results in enhanced voltage and electrostatic discharge (ESD) performance over standard capacitor designs while allowing for a fail-open condition if mechanically damaged (cracked). The capacitance change with reference to ambient temperature is limited to ±15% (X7R) and ±30 ppm/ºC (C0G) from -55°C to +125°C.

Whether under the hood or in the cabin, these capacitors are designed to provide reliable performance in mission and safety-critical automotive circuits. Stricter testing protocols, as well as inspection criteria, have been established for automotive-grade products in awareness of potentially harsh environmental conditions. KEMET automotive-grade series capacitors meet AEC-Q200 qualification requirements.
