RA7338 Series

Power Inductor for Microchip 1600W Bus Balancer

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)

メモ

Inductance measured at 100 kHz, 0.1 Vrms, using an Agilent/HP 4192A LCR meter or equivalent.
DCR measured at 25°C on a Keithley 580 micro-ohmmeter or equivalent. For other operating temperatures, use this DCR at Temperature calculator.
SRF measured using an Agilent/HP 8753ES network analyzer.
Isat: DC current at 25°C that causes the specified inductance drop from its value without current. Temperature derating curves.
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.

終端処理:

RoHS compliant tin-silver over copper.
