C0G and Ultra-Stable X8R Capacitors Employ Proven Flexible Termination Technology

KEMET Corporation announced the expansion of its flexible termination (FT-CAP) portfolio to include C0G and Ultra-Stable X8R dielectrics.

Electronic components are often subjected to severe flexing and vibration when used in various under-the-hood automotive and other harsh environment applications. Potential mishandling during circuit board assembly may also expose these components to excessive flex and mechanical stresses. In these situations, KEMET's flexible termination technology is a successful and proven solution in minimizing the risk of damage to the multilayer ceramic capacitor (MLCC).

KEMET's C0G-type capacitors, combined with flexible termination technology, are said to offer exceptional capacitance stability up to 125° C while addressing the need for more flex-robust solutions in automotive, telecom, mobile communications, power supply and audio applications. For high temperature applications, the Ultra-Stable X8R-type capacitors with flexible termination are ideal for mitigating flex cracks that may develop under excessive board flex conditions associated with assembly, handling and extreme environments up to 150° C.

Both dielectric technologies are Lead-Free and RoHS Compliant, and are suited for a variety of applications requiring proven, reliable performance. In addition to Commercial Grade, Automotive Grade devices are available for mission and safety critical circuits requiring stricter testing protocol and inspection criteria.

KEMET's Flexible Termination (FT-CAP) multilayer ceramic capacitors incorporate 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. This technology was developed in order to address flex cracks, the primary failure mode of surface mount MLCCs, and reduce the risk of mechanical damage to the component that can result in low IR or short circuit failures.

Ultra-Stable X8R dielectric offers the same temperature capability as conventional X8R but without the capacitance loss due to applied DC voltage. These devices are a suitable replacement for higher capacitance and larger footprint devices that fail to offer capacitance stability.
