Power supply capacitors

  • 16-Apr-2010 02:59 EDT

Spectrum’s Switch Mode Power Supply capacitors have achieved MIL-PRF-49470 approval and are said to perform better than tantalum or aluminum electrolytic capacitors, featuring low equivalent series resistance and equivalent series inductance. The capacitors are suited for input/output filtering for military and high-reliability power supplies as well as high-capacitance discharge units. Functioning at high frequencies or high power, the units have a capacitance of up to 47 µF, with tolerances of 5%, 10%, or 20%. They withstand temperatures of -55 to +125°C and are offered in through-hole or surface-mount leaded configurations of N, J, or L. In addition, B, P, BX, BR, or BQ ceramics are available and can withstand voltages from 50- to 500-V dc.
