Hammond EMI/RFI Chokes - (1538 & 1539 Series)

EMI/RFI
CHOKES

Key Features:

High saturation flux density ferrite rods.
1" long leads, tinned to within 1/8" of body.
Ideal for filtering or energy storage inductors.
Inductance measured at @ 1Khz. with 0 amps. D.C. current, typical inductance change is less than 5% @ twice rated current.
