High Reliability DC Link Power Film Capacitors Ideal for Power Inverter Applications
Fairview, PA - Spectrum Advanced Specialty Products now offers DC link power film capacitors with voltage ratings up to 1300 VDC. Due to harsh operating conditions of wind and photovoltaic installations, components used in power inverter applications require superior life expectancy. Spectrum's DC link power capacitors utilize segmented, self-healing metallized polypropylene, internally fused using a T-design pattern, giving them a life expectancy of over 100,000 hours.
Spectrum's DC link power film capacitors feature low ESR (1 to 4.3 mW, typ.) and low ESL (50 to 80 nH, typ.), 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 ideal replacements for electrolytic capacitors. Custom, application-specific designs are welcome, with a variety of terminations and specifications available.
