The RL181S-183J-RC is a shielded radial lead RF choke from Bourns' RL181S series, engineered for use in DC/DC converters, power supplies, and output filtering applications. This component features an inductance of 18,000 µH with a tolerance of ±5%, a minimum Q factor of 100 at 50 kHz test frequency, and a self-resonant frequency (SRF) of 0.19 MHz. The choke exhibits a DC resistance (DCR) of 17.0 O and supports a DC current rating of 21 mA, making it suitable for moderate-power filtering and energy storage applications. Its shielded construction and high Q characteristics provide excellent performance in noise suppression and signal integrity, while RoHS compliance ensures environmental compatibility for modern electronic systems.
