The Bourns RL622 series is a radial lead RF choke coil designed for various applications including DC/DC converters and power supplies. This series offers a wide range of inductance values, from 1µH to 100,000µH, to meet diverse circuit requirements. The RL622-181K-RC specifically features an inductance of 180µH, a tolerance of ±10%, and is RoHS compliant. While this series is not recommended for new designs, the Model RLB0913 Series is the recommended alternative. Its ferrite core and enameled copper wire construction ensure efficient performance and durability.
