Switch-mode power supply (SMPS) capacitors are designed to provide superior
performance in high-frequency switching applications. SMPS capacitors are ideal for high energy density products found in both military and commercial markets. Spectrum Control's ceramic capacitors are designed and produced in the USA.
Spectrum Control can design products in accordance with DSCC 87106 and MIL-PRF-49470 standards. Visit Military Standard Qualified EMI Filters to see the cross-reference lists.
