Spectrum’s Switch Mode Power Supply Capacitors Receive Military QPL Approval

April 04, 2010 by Jeff Shepard

Spectrum Advanced Specialty Products announced the addition of MIL-PRF-49470 approval for Switch Mode Power Supply capacitors to its military QPL offerings. Spectrum’s SMP capacitors have better performance than tantalum or aluminum electrolytic capacitors, featuring low ESR and ESL. These capacitors, available in industry-standard or custom case sizes, are all made in Spectrum’s established MIL-STD-70 ceramic facility located in State College, Pennsylvania.

Spectrum’s Switch Mode Power Supply capacitors are well suited for input/output filtering for military and high reliability power supplies and high capacitance discharge units. Functioning at high frequencies or high power, these capacitors have a capacitance of up to 47µF, with tolerances of 5, 10 or 20%. The capacitor is designed to withstand temperatures ranging from -55 to +125°C, making it a suitable choice for a broad range of environments. To help safeguard the device from thermal and mechanical stresses, the capacitor is offered in through-hole or surface mount leaded configurations of N, J or L. Additiona lly, BP, BX, BR or BQ ceramics are available, all able to withstand voltages ranging from 50 to 500Vdc.

The MIL-PRF-49470 qualified Switch Mode Power Supply product adds to the already wide range of Spectrum QPL listings. With the largest number of MIL-PRF-15733, MIL-PRF-28861 and legacy 87106, DSCC 84084 and MIL-C-11015 products, Spectrum states that it is considered a primary supplier for many aircraft, ship and weapons programs maintained by NATO defense branches.
