Selfs - Power Inductors Universal Application - FAMILLE 45H27-45V30 44H27-44V30



CASE VERSION Voltage 250 Vac
Current 0.5 to 3 A

These chokes are fitted with toroid core in iron powder. They have large independence of inductance
value from current. They are mainly used as line filters and noise suppressors in switched-mode power
supplies, and as storage chokes; double chokes can also be used as transformer.
