Military and commercial markets continue to demand capacitors capable of high-reliability, long lifetime performance at operating temperatures in excess of the current 125° C. The AT Series MLCCs offer 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 industry-leading 250° C parts.
These high temperature MLCC capacitors reliably test data at 250° C, and are rated at both 250° C and 200° C for de-rating schemes. The series exhibits high current-handling capabilities, high volumetric efficiency, high insulation resistance, and extremely low ESR and ESL, in addition to 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 to 2225), values (100 pF to 1 µF), voltages (16 to 50 V), and dielectrics (C0G and VHT), AT capacitors perform in demanding automotive, avionics, aerospace and energy applications.
They are suitable for: automotive applications, including under hood power, engine control units, and hybrid electric and plug-in electric vehicles (HEVs and PEVs); avionics and aerospace applications, including transducers, engine controls, spacecraft, and flap and brake controls; and energy applications, including down-hole oil exploration, logging while drilling, geophysical and geothermal probes, seismic sensors, and solar and wind energy conversion.
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.
