Available in case sizes 1-6, AVX's BX characteristic (X7R dielectric), horizontally stacked SMPS capacitors has received T-Level MIL-PRF-49470 qualification approval. The 25V unencapsulated capacitors extends AVX's existing portfolio of BX characteristic SMPS capacitors listed on the MIL-PRF-49470 QPL.

The 25V capacitors feature a capacitance range of 1.5µF to 390µF, and are rated for -55°C to +125°C. The capacitors are designed 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.

Also available is the SpiCalci 8.0 SPICE modeling software which aids designers in validating circuits before they are built, allowing them to simulate frequency performance plots and other data for specific AVX components.

“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,” commented 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.”
