Their low inductance construction and low-loss winding technology make them ideal for the next generation of high power-dense inverter and converter designs. Their rugged plastic case with integrated mounting flanges, threaded stud or insert termination options, allow for easy, secure mounting. This series is ideal for DC Fast EV Charging and for high power solar inverters and motor drives. Highlights

  • Designed for higher switching frequencies
  • Up to 60% lower ESL (Equivalent Series Inductance)
  • High ripple current

For operation below 10 kHz, the ESR will need to be adjusted using the following equation: ESR - 31.83/(10C) + 31.83/(fC). Determine Thermal Resistance at Operating Frequency and Air Flow Compute Θ = ΘCC + ΘCA. In the ratings tables, ΘCA is for still air. For v = 0 to 5 m/s, Determine Expected Lifetime Look up Expected Lifetime on the graph using VA/VR and TC = TA + I2 (ESR/1000) Θ The maximum allowed temperature rise is 40 °C and the maximum allowed core temperature is 95 °C.
