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

Fairview, PA – April 6, 2010 – Spectrum Advanced Specialty Products announces the addition of MIL-PRF-49470 approval for Switch Mode Power Supply capacitors to its extensive military QPL offerings. Spectrum’s SMP capacitors have a 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, PA.

Spectrum’s Switch Mode Power Supply capacitors are excellent 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 180 microfarads, with tolerances of 10% or 20%. The capacitor is designed to withstand temperatures ranging from -55 degrees Celsius to +125 degrees Celsius, making it an ideal 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. Additionally, BP, BX, BR or BQ ceramics are available, all able to withstand voltages ranging from 50 to 500 VDC.

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 is considered a primary supplier for many aircraft, ship and weapons programs maintained by NATO defense branches. Spectrum is also an ideal choice for competitively priced drop-in replacement and repair products.

As a trusted military partner, Spectrum ensures the quality and reliability of each QPL product through its unique in-house testing capabilities. With both EMC and environmental testing, Spectrum offers the most comprehensive EMI evaluation and design resource available. Testing capabilities include environmental stress screening (ESS), analytical circuit design, surge testing and mechanical shock resistance testing. All testing results are integrated into the design process, resulting in an optimum product that will withstand even the harshest environments.
