KEMET Flex Mitigation MLCCs

Flexible Termination Cross Section

FT-CAP

KEMET 's Flexible Termination (FT-CAP) multilayer ceramic chip capacitors (MLCCs) offer a unique, flexible termination system that is integrated with KEMET 's standard termination materials. A conductive silver epoxy is utilized between the base metal and nickel barrier layers of KEMET's standard termination system in order to establish pliability while maintaining terminal strength, solderability and electrical performance. The flexible termination technology within the FT-CAP MLCC provides superior flex performance (up to 5mm) over standard termination systems. High voltage (HV FT-CAPs) are also available in DC voltage ratings of 500V, 630V, 1KV, 1.5KV, 2KV, 2.5KV, and 3KV. The Flexible Termination is also available on X8L Dielectric devices that offer a higher operating temperature range up to 150ºC.

NEW!  KEMET has expanded the Flexible Termination (FT Cap) MLCC product offerings to include FT Caps in a C0G dielectric.  The Flexible Termination C0G MLCCs from KEMET offer superior flex performance (up to 5mm), capacitance range from 0.5pF to 0.47µF, and voltage range from 10V to 200V.  Learn More

Floating Electrode Cross Section

KEMET 's Floating Electrode with Flexible Termination capacitors (FF-CAP ) combines two KEMET technologies - Floating Electrode and Flexible Termination. The floating electrode component utilizes a cascading internal electrode design configured to form multiple capacitors in series within a single monolithic structure, a unique design that results in enhanced voltage and ESD performance over standard capacitor designs while allowing for a fail-open condition if mechanically damaged (cracked). The flexible termination component utilizes a conductive silver epoxy between the base metal and nickel barrier layers of KEMET's standard termination system in order to establish pliability while maintaining terminal strength, solderability and electrical performance. Both technologies address the primary failure mode of MLCCs -flex cracks, which are typically the result of excessive tensile and shear stresses produced during board flexure and thermal cycling.

Floating Electrode Cross Section

FE-CAP

The KEMET Fail-Safe Floating Electrode MLCC/FE-CAP utilizes a floating internal electrode design, where electrodes form multiple capacitors in a single MLCC package. Improved voltage and ESD performance over standard designs lower risk of low-IR or short-circuit failures that may occur due to board flex. The unique electrode configuration of the FE-CAP MLCCs from KEMET also allows for a fail-open condition if the capacitor is mechanically damaged (cracked). If damaged, the capacitor may lose capacitance, but a short is unlikely. FE-CAP MLCCs offer low to mid-capacitance flex mitigation.

Open Mode Cross Section

FO-CAP

KEMET'S Open Mode FO-CAP capacitor significantly minimizes the chance of a short because a flex crack will not typically propagate across counter electrodes within the device's "active area." The lack of current leakage from the Open Mode flex crack eliminates localized heating, therefore, greatly reducing the risk of a catastrophic and costly failure event. Open Mode designed devices compliment KEMET 's Floating Electrode (FE-CAP) and Floating Electrode with Flexible Termination (FF-CAP) products by providing a fail-safe design optimized for mid to high-range capacitance values.
