Spectrum Advanced Speciality Products debuts DC link power film capacitors that use segmented, self-healing metallized polypropylene, internally fused using a T-design pattern designed for a life expectancy of over 1,00,000 hours targeting power inverter applications operating under harsh conditions in wind and photovoltaic installations.

With voltage ratings up to 1,300VDC, the capacitors feature ESR of 1mΩ to 4.3mΩ, typ. and ESL of 50nH to 80nH, typ. They have ripple currents up to 70A RMS from 10kHz to 100kHz, and a capacitance range of 160µF to 680µF standard. All capacitors are tested to the environmental specifications of MIL-STD-202, and come in a compact, cost-effective design. The high capacitance density and ripple current capabilities of DC power link capacitors make them suitable replacements for electrolytic capacitors.

Custom, application-specific designs are welcome, with a variety of terminations and specifications available.
