KEMET is First Supplier to Offer Both Class-I and Class-II MLCCs Qualified to MIL-PRF-32535  

Industry-Leading Base Metal Technology Enhances Ceramic Defense and Aerospace Portfolio  

FORT LAUDERDALE, Fla., June 18, 2018 (GLOBE NEWSWIRE) -- KEMET Corporation (NYSE:KEM), a leading global supplier of electronic components, today announced that it is the first and only supplier to offer both Class-I and Class-II base metal electrode (BME) multilayer ceramic capacitors (MLCCs) qualified for defense and aerospace applications by the Defense Logistics Agency (DLA). The DLA recently accepted KEMET's X7R dielectric MIL-PRF-32535 for "M" and "T" reliability levels.

MIL-PRF-32535 is the first DLA capacitor specification for defense and aerospace that capitalizes on industry-leading base metal electrode (BME) technology. In December 2017, KEMET announced DLA approval for C0G and BP Class-I dielectrics which are ideal for critical timing, tuning, pulse, AC, and transient voltage suppression applications where capacitance stability may be a concern. With the recent DLA approval of KEMET’s X7R Class-II dielectric, design engineers will now have access to ceramic capacitors that offer up to a 55-fold increase in capacitance values as compared to the offerings under traditional specifications using precious metal electrodes (PME). These capacitors are ideal for decoupling, bypass, filtering, and bulk storage for military, avionics and space applications.

MIL-PRF-32535 is also the first DLA specification to recognize a flexible termination option. KEMET's flexible termination utilizes a pliable conductive silver epoxy in the termination system. The addition of this epoxy layer inhibits the transfer of board stress to the rigid ceramic body, therefore mitigating flex cracks that can result in low insulation resistance or short circuit failures.

“KEMET has been a leader in BME ceramic capacitor development for over 20 years,” said Dr. Abhijit Gurav, KEMET Vice President of Ceramic Technology. “These new Class-I and Class-II capacitor ranges were qualified through the extremely stringent requirements of the MIL-PRF-32535 specification, and still offer significantly higher capacitance values than the MIL-PRF-123 and 55681 specifications. This enables more circuit functionality in defense and space applications while allowing significant component miniaturization and payload weight reduction.”
