• High Voltage with Flexible Termination System | KEMET

Featuring a 125°C maximum operating temperature and considered "temperature stable," these devices address the primary failure mode of MLCCs—flex cracks, which are typically the result of excessive shear stresses produced during board flexure or thermal cycling. Utilizing a conductive silver epoxy between the base metal and nickel barrier layers of KEMET’s standard termination system, flexible termination technology directs board flex stress away from the ceramic body and into the termination area, therefore mitigating flex cracks which can result in low IR or short circuit failures. Although flexible termination technology does not eliminate the potential for mechanical damage that may propagate during extreme environmental and handling conditions, it does provide superior flex performance over standard termination systems.

The HV FT-CAP offers low leakage current, exhibits low ESR at high frequencies and finds conventional use as snubbers or filters in applications such as switching power supplies and lighting ballasts. Their exceptional performance at high frequencies has made them a preferred choice of design engineers worldwide.

Combined with the stability of an X7R dielectric and designed to accommodate all capacitance requirements, these flex-robust devices are RoHS-compliant, offer up to 5mm of flex-bend capability and exhibit a predictable change in capacitance with respect to time and voltage. Capacitance change with reference to ambient temperature is limited to ±15% from -55°C to +125°C.
