High Reliability DC Link Power Film Capacitors

摘要

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 installa-. tions, 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 mΩ, typ.) and low ESL (50 to 80 nH, typ.), ripple currents up to 70A RMS from 10kHz to 100kHz, and a capacitance range of 16OμF to 680uF standard.
