Operating over a temperature range from -55 to +200°C, the MLCCs are designed for use in high temperature, harsh environment applications, including: down-hole oil, gas and mineral exploration; military, defence and weapons systems; space and satellite communications; automotive underhood and HEV; rugged AC/DC power converters; DC filters in high power, high frequency ripple currents, high pulsed-current circuitry, and a range of low power electronics; EMI filters on AC inputs; DC link capacitors for AC/AC and DC/AC motor drive inverters; and start-and-run capacitors in AC induction motors.
Constructed using high temperature solder, the capacitors provide rugged thermal shock, mechanical shock, moisture resistance and vibration resistance capabilities per MIL-STD-202. The stacked SMPS capacitors are available in C0G and X7R dielectrics, six case sizes, voltage ratings of 25-500V and capacitance values of 0.0039-270µF.
Customisation options include custom geometries, packages, terminals, lead configurations and stress relief mounting options. This enables engineers to achieve higher efficiency, space-saving designs with enhanced mechanical and thermal reliability.
Stan Cygan, Senior Applications Engineer, AVX, stated: “With the addition of the new capacitance and voltage ratings, AVX’s extensively customisable SMX series now offers the widest selection of stacked SMPS capacitors rated to 200°C in the industry, providing much-needed design solutions for an even broader range of high temperature, harsh environment applications than before.”
