Epcos (B82145A1475J000) RF Choke, B82145A, HLBC, 4.7mH

Product Description

The Epcos B82145A1475J000 is a leaded RF choke from the HLBC series, rated at 4.7 mH, built with a large ferrite drum core and enamel copper wire winding with a flame-retardant lacquer coating. It offers a current rating of 170 mA with a DC resistance of 18Ω, and a self-resonant frequency of 500kHz. Suitable for wave soldering, its terminals are radially bent to 5mm lead spacing and electroplated with nickel and pure tin for reliable, long-term connections. It's well-suited for interference suppression, decoupling, energy-saving lamp circuits, and entertainment electronics applications requiring high current at higher inductance ratings.
