RA7338 Series

Power Inductor for Microchip 1600W Bus Balancer

RoHS-konform Halogenfrei AEC-Q flag
Coilcraft AEC-Q200 Grade-1 RA7338 Series power inductors are ideal for automotive applications and other high-temperature environments. RA7338 Series are designed for high-efficiency power supplies requiring high current and high inductance.
 
  • Developed for Microchip 1600W Bus Balancer Reference Design
  • Flat wire windings provide extremely low DC and AC resistance. 
  • Low loss ferrite cores provide flat L vs I
  • Magnetic shielding to minimize EMI
  • Vertical (TH) mounting for rugged board attachment
  • Shield has solderable tabs for additional mounting stability
  • AEC-Q200 Grade 1 (−40°C to +125°C)

Hinweise
  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.
  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.
