High-temperature MLCCs

23 September 2015 Passive Components

AVX has extended its high-temperature AT Series MLCCs with two new case sizes (0603 and 0805), two new voltage ratings (16 V VHT 250°C and 25 V VHT 200°C), and new C0G and VHT temperature coefficients that differentiate the 200°C parts from the 250°C models.

Designed to accommodate emerging military and commercial 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 come with reliability test data at 250°C, and are rated at both 250°C and 200°C to provide engineers with optimal derating schemes.

The series exhibits high current handling capabilities, high volumetric efficiency, high insulation resistance, and extremely low ESR and ESL, in addition to excellent high-frequency performance and capacity retention with frequency, and low parasitics and DC leakage for circuit stability and efficiency. Now available in an extended range of sizes (0603 – 2225), values (100 pF – 1 μF), voltages (16 – 50 V) and dielectrics (C0G and VHT), the capacitors perform in the most demanding automotive, avionics, aerospace and energy applications.

The series can also be used as decoupling and bypass capacitors and for DC filtering in motor drives and high-frequency ripple currents, and is also well suited for use in sensors and timing circuits, high-pulsed current circuitry, DC-DC power conditioning converters, DC current sensing and subsystems, AC-DC converters and DC-AC inverters.
