The Bourns RL622 series is a radial lead RF choke coil designed for a variety of applications including DC/DC converters, power supplies, and desktop notebooks. This series offers a wide range of inductance values, from 1µH to 100,000µH, and is RoHS compliant. While this series is no longer recommended for new designs, the Model RLB0913 Series is a suitable alternative. The RL622-180K-RC specifically features an inductance of 18µH, a tolerance of ±10%, and a self-resonant frequency (SRF) of 11 MHz, making it suitable for filtering and noise reduction in electronic circuits. Its ferrite core and enameled copper wire construction ensure reliable performance and durability.
