MLCCs operate higher than 125°C
A series of high temperature MLCCs, fulfilling the demand for capacitors that operate higher than 125°C, has been launched by AVX. The AT Series capacitors feature high current handling capabilities, high volumetric efficiency, high insulation resistance, and extremely low ESR and ESL. The devices are suited for use as filters in the power electronics, switch mode power supplies, and DC/DC converters designed into a broad range of automotive, avionics and aerospace and energy applications.
Rated to 16V and 25V at operating temperatures spanning -55°C to +250°C, the capacitors are available in both C0G (Class I) and VHT (Class II) dielectrics. The series includes capacitance values from 2200pF to 1µF, with capacitance tolerances down to ±5%; ±10%, and ±20% also available. The MLCCs feature two termination options (Pd/Ag & RoHS-compliant 100% Sn plated) and case sizes ranging from 1206 to 2225.
“Present military specifications and a majority of commercial applications currently require a maximum operating temperature of 125°C. However, the market for high temperature electronics is expanding rapidly and demands capacitors that are capable of reliable, long-term operation at temperatures well beyond 125°C,” said Stan Cygan, senior applications engineer at AVX. “We developed the new AT Series MLCCs in direct response to these market demands and plan to continue expanding the already extensive range of size, value, and voltage options to provide the automotive, aerospace, and energy industries with a comprehensive range of high-reliability, high-temperature solutions.
