MLCC high voltage floating electrode design

KEMET Electronics Floating Electrode High Voltage, available now from Mouser, 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 ESD performance over standard capacitor designs while allowing for a fail-open condition if mechanically damaged (cracked). The capacitance change regarding ambient temperature is limited to ±15% (X7R) and ±30ppm/C (C0G) from -55C to +125C.

These capacitors are created to deliver reliable performance in mission and safety-critical automotive circuits, whether under the hood or in the cabin. Stricter testing protocols and 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. The devices are lead-free, RoHS and REACH compliant.

Typical application areas include EV/HEV (drive systems, charging), LCD fluorescent backlight ballasts, power converters, and LAN/WAN interfaces; EV/HEV (drive systems, charging), high-frequency power converters, WBG, SiC, and GaN systems, and snubber (high dV/dT).
