RL181S Radial Lead RF Chokes

Bourns RL181S Radial Lead RF Chokes feature up to 90mA current rating and 1000µH to 120,000µH inductance range with ±5% inductance tolerance. These chokes offer high Q, shielded construction, and ferrite core material. The series is RoHS compliant and operates in a -55°C to +105°C temperature range. These chokes are formerly J.W. Miller® products. Bourns RL181S Radial Lead RF Chokes are ideally suited for applications such as DC/DC converters, power supplies, desktop notebooks, and output chokes.
