Axially Leaded Miniature
Power Inductors
Model HM50
Magnecs
Features and Benets
Inductance Range 3.9μH to 18,000μH
Standard Tolerance ±10%
Operang Temperature Range -55°C to +105°C
RoHS Compliant
Notes:(1) Inductance is measured at 1kHz without DC current.
(2) The rated DC current is based on an approximate 20°C temperature rise.
(3) The incremental current (INCR I) is the approximate current at which the inductance will be decreased by 5% from its inial (zero DC) value due to saturaon.
