Specifications

Electrical specifications at 25°C.

Part number Inductance (µH) 1
(Tolerance: ±10%) 		DCR max (Ω) 2 SRF typ (MHz) 3 Isat (A) 4 Irms (A) 5
L0451-AL 180 0.052 3.2 14.0 7.0
Notes
  1. Inductance measured at 1 kHz, 0.1 Vrms, 0 Adc using an Agilent/HP 4192A impedance analyzer or equivalent.
  2. DCR measured at 25°C on a micro-ohmmeter. For other operating temperatures, use this DCR at Temperature calculator.
  3. SRF measured on an Agilent/HP 8753D network analyzer.
  4. Isat: DC current at which inductance drops 10% (typ) from its value without current. 
  5. Irms: Crrent that causes a 40°C rise from 25°C.

Termination:

  • RoHS tin-silver over copper
