The 100V, 200V, and 500V BP characteristic (C0G [NP0]) horizontally stacked SMPS capacitors in encapsulated and unencapsulated styles in case sizes 3, 4, and 5 have received T-Level MIL-PRF-49470 qualification approval. The capacitors are suitable for I/O filtering and bulk storage in a variety of military, space, harsh environment and high voltage applications.

Target end applications for the SMPS capacitors include military defense and weapons systems, space and satellite communications, telecom switching, networking, base stations, DC/DC power converters, high voltage medical electronics, industrial equipment, down hole drilling equipment, oil exploration equipment, alternative vehicles and hybrid energy vehicles.

Available in 100, 200 and 500V, AVX’s high reliability T-Level C0G (NP0) SMPS capacitors feature a capacitance range up to 1.8µF. With a capacitance range up to 2.2µF, the standard reliability B-Level C0G (NP0) SMPS capacitors are available in 50, 100, 200 and 500V. Both the T- and B-Level C0G (NP0) SMPS capacitors have an operating temperature range from -55 to +125°C.

AVX also offers SpiCalci 8.0 SPICE modeling software (allowing design engineers to simulate frequency performance plots and other data for specific AVX components, which helps them validate circuits before they are built) for the full offering of C0G (NP0) SMPS capacitors approved on the MIL-PRF-49470 qualified parts list.

Patrick Hollenbeck, Application Engineer, AVX, commented: “Available in encapsulated and unencapsulated styles, various case sizes, and a broad range of voltage and temperature characteristics, AVX has the most extensive qualified parts listing of both standard and high-reliability SMPS capacitors available. In fact, AVX MIL-PRF-49470 SMPS capacitors are the leading solution for I/O filter capacitors in military switch mode power supplies.”
