SMPS Capacitors Are MIL-PRF QPL Approved

AVX Corporation has received T-Level MIL-PRF-49470 qualification approval for its new 25 V, 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 25 V, 50 V, and 100 V encapsulated and unencapsulated styles with both high reliability T-Level qualification for space applications and standard reliability B-Level qualification (similar to DSCC 87106) for military, harsh environment, and high voltage applications.

Featuring a capacitance range of 1.5 µF to 390 µF 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.

SpiCalci 8.0 SPICE modeling software, which helps design engineers validate circuits before they are built by allowing them to simulate frequency performance plots and other data for specific AVX components, is available for the full offering of BX characteristic SMPS capacitors approved on the MIL-PRF-49470 QPL.  To download the SpiCalci 8.0 executable file, please visit: http://www.avx.com/SpiApps/default.asp#spicalci.
