Bourns RL622 Series Radio Frequency Radial Inductors RL622 radial RF chokes from Bourns, previously referred to as the ’J. W. Miller’ model, offer current ratings up to 10 A. RL622 radial RF cokes are constructed from a ferrite core with enamelled copper wire and the terminals have a tin coating. These RF chokes are available with inductance values between 1 μH and 100000 μH. Product Application Information Suitable applications for these radial RF chokes include power supplies, DC-DC convertors, output chokes and desktop notebooks.
