The RL622-393K-RC is a radial lead RF choke from the Bourns RL6222 Series designed for RF filtering and energy storage in power conversion circuits. This inductor features an inductance of 39,000 µH (39 mH) with a tolerance of ±10%, a minimum quality factor (Q) of 30 at 79.6 kHz test frequency, and a self-resonant frequency (SRF) of 0.1 MHz. The device has a maximum DC resistance of 80 O and supports a DC current rating of 0.03 A, making it suitable for low-current, high-inductance applications. The RL622-393K-RC is RoHS compliant and finds common use in DC/DC converters, power supplies, desktop notebooks, and output choke applications where stable inductance and low losses are required.
