AVX has introduced a new series of high temperature MLCCs rated for 250°C. Designed to meet market demands for capacitors capable of high-reliability, long lifetime performance at operating temperatures in excess of the current 125°C requirement, AT Series capacitors exhibit high current handling capabilities, high volumetric efficiency, high insulation resistance, and extremely low ESR and ESL. Available in a wide range of sizes, values, and voltages - all rated at 250°C - in addition to two dielectrics and multiple termination options, AT Series capacitors provide exceptional performance in the most demanding automotive, avionics, aerospace, and energy applications.
AT Series MLCCs are suitable for use as filters in the power electronics, switch mode power supplies, and DC/DC converters designed into a broad range of automotive applications, including: under hood, hybrid electric vehicle, engine control, sensor, and timing circuit applications; avionics and aerospace applications, including: transducer, engine control, spacecraft, flap and brake control, sensor, and timing circuit applications; and energy applications, including: down-hole oil exploration, logging while drilling, geophysical probe, seismic, geothermal, wind, solar, sensor, and timing circuit applications.
Rated to 16V and 25V at 250°C and for operating temperatures spanning -55°C to +250°C, AT Series MLCCs are available in both C0G (Class I) and VHT (Class II) dielectrics. The series includes capacitance values spanning 2200 pF to 1µF with capacitance tolerances down to ±5%; ±10%, and ±20% are also available. Featuring two termination options (Pd/Ag & RoHS-compliant 100% Sn plated) and case sizes ranging from 1206 to 2225, future expansions of the AT Series are to include higher CV, higher voltage, and automotive qualified components.
