AVX has received T-Level MIL-PRF-49470 qualification approval for its new 25V, unencapsulated, BX characteristic (X7R dielectric), horizontally stacked SMPS capacitors in case sizes 1-6. The new components further expand AVX’s already extensive offering of BX characteristic SMPS capacitors listed on the MIL-PRF-49470 QPL, which now includes 25V, 50V, and 100V unencapsulated and 50V and 100V encapsulated styles with high reliability T-Level qualification for space applications.
AVX also offers B-Level qualification (similar to DSCC 87106) for 25V, 50V, and 100V encapsulated and unencapsulated styles for military flight, and harsh environment applications.
Featuring a capacitance range of 1.5µF to 390µF and rated for -55°C to +125°C, AVX’s B- and T-Level BX characteristic SMPS capacitors are ideal for I/O filtering and bulk storage in a wide range of applications, including: military defense and weapons systems; space and satellite communications; telecom switching, networking, and base stations; DC/DC power converters; high voltage medical electronics and industrial equipment; down hole drilling and oil exploration equipment; and alternative and hybrid energy vehicles.
“AVX has the most extensive QPL listing of standard and high-reliability SMPS capacitors in both encapsulated and unencapsulated styles and in a broad range of voltage and temperature characteristics, making them ideal for use in a wide variety of military, space, and other harsh environment applications,” said Patrick Hollenbeck, applications engineer at AVX. “In fact, AVX MIL-PRF-49470 SMPS capacitors are the leading solution for I/O filter capacitors in military switch mode power supplies.”
