BLS Series 125°C Metallized Polypropylene Film DC-Link Capacitors

Cornell Dubilier Knowles BLS series capacitors set performance standards for THB-rated, board-mount DC link capacitors

Image of Cornell Dubilier Knowles BLS Series Metallized Polypropylene Film DC-Link CapacitorsCornell Dubilier Knowles BLS series DC Link capacitors use the most advanced construction and technology to meet the challenges of harsh environments with operating temperatures of up to +125°C. They are tested for 2,000 hours at +85°C/85% relative humidity with rated voltage applied (50% greater than competitive THB test life). This series is qualified for automotive-grade electrical and mechanical testing per standard AEC-Q200.

Features
  • Optimized for DC link and inverter circuits
  • THB rated
  • 100% greater life under THB test conditions
  • 2,000 hour life load based on +85°C at 85% relative humidity with voltage applied
  • Able to withstand harsh and humid conditions
  • High capacitance with high ripple current
  • Self-healing for added reliability
  • Capacitance ranges from 1.0 µF to 220 µF at 450 VDC to 1100 VDC
  • High RMS current ratings for handling higher-ordered harmonics
  • Meets IEC61071, AEC-Q200 and RoHS
  • Suitable for high-frequency applications
  • Life expectancy: 100,000 h @ +70°C hot spot, at rated voltage
Applications
  • Inverters using broadband semiconductors (SiC)
  • Solar, EV, and other inverters subjected to wide-ranging natural environmental conditions
  • Backup, UPS, and portable power systems
  • Motor drives
  • DC-link and power output filtering
  • EV battery chargers and other transportation systems
