CU8838-AL

High Current Shielded Power Inductor

RoHS-konform
Coilcraft's CU8838-AL power inductor is mechanically rugged and magnetically shielded for use in high-density circuits. Flat-wire construction provides excellent current handling and exceptionally low DCR, and soft saturation makes them perfect for VRM/VRD applications. 
  • Exceptionally low DC resistance
  • Soft saturation for high peak current handling
  • Magnetic shielding for high-density packaging
  • Ideal for low-voltage, high-current DC-DC converters and VRD/VRM controllers
  • No thermal aging

Hinweise
  1. When ordering, please specify packaging code: e.g. CU8838-ALD
  2. Inductance tested at 100 kHz, 0.1 Vrms using a Coilcraft SMD-A fixture and an Agilent/HP 4284A LCR meter.
  3. DCR measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator
  4. SRF measured using an Agilent/HP4291A impedance analyzer or equivalent and a Coilcraft16193 fixture.
  5. Isat: DC current at which the inductance drops the specified amount from its value without current. Details
  6. Irms: Current that causes specified temperature rise from 25°C ambient. Details

Anschlüsse:

  • RoHS tin-silver over copper.
