RA7338 Power Inductor for Microchip 1600W Bus Balancer

  • Developed for Microchip 1600W Bus Balancer Reference Design
  • Designed for high current power supply applications
  • Flat wire windings provide extremely low DC and AC resistance
  • Suitable for high temperature environments – up to 125°C ambient
  • AEC-Q200 Grade 1 qualified (−40°C to +125°C)
  • Shield has solderable tabs for additional mounting stability
  • RoHS-compliant. Tin-silver over copper terminations.

1 Inductance measured at 100 kHz, 0.1 Vrms, using an Agilent/HP 4192A LCR meter or equivalent.
2 DCR measured at 25°C on a Keithley 580 micro-ohmmeter or equivalent. For other operating temperatures, use this DCR at Temperature calculator.
3 SRF measured using an Agilent/HP 8753ES network analyzer. Details
4 Isat: DC current at 25°C that causes the specified inductance drop from its value without current.
Temperature derating curves.
5 Irms: Current that causes the specified temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings. Temperature derating curves.
6 Ambient temperature range: −40°C to +125°C with Irms current.
7 Storage temperature range: Component: −40°C to +85°C
Packaging trays: −40°C to +80°C
8 Maximum part temperature: +165°C (Ambient + temperature rise)
9 Electrical specifications at 25°C.
