TDK B82721K2501N001 B82721 SMD Choke 18 mH 1400 mΩ 0.5 A Toroidal core

TDK B82721K2501N001 is a toroidal core surface-mount device (SMD) choke that serves a critical role in electronic circuitry for suppression and filtering tasks. This choke features an inductance of 18 millihenries (mH) and a resistance of 1400 milliohms (mO), with an operational current capacity of 0.5 amperes (A). Designed for efficient energy transfer and minimal electromagnetic interference, it is particularly suited for use in moving coil meter applications and other precision instrumentation where high inductance and reliable performance are essential. The compact SMD design facilitates easy integration into densely packed circuit boards, making it an ideal choice for modern electronic systems requiring efficient use of space and effective noise filtering.
