High Voltage with Flexible Termination System (HV FT-CAP)

KEMET's High Voltage with Flexible Termination (HV FT-CAP) surface mount MLCCs in X7R dielectric, combine high voltage and flexible termination technologies. 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. In addition to their use in power supplies, these capacitors are widely used in industries related to telecommunications, medical, military, aerospace, semiconductors, and test/diagnostic equipment.
