RLB0912-102KL is a radial inductor from the Bourns RLB Series designed for high-current power supply and DC/DC converter circuits. The device features a 1000 µH inductance (±10%) with a ferrite DR core and enameled copper wire construction, providing reliable performance in demanding applications. Key electrical characteristics include a maximum DC resistance of 4.3 O, a maximum DC current rating of 0.20 A, a self-resonant frequency of 1.9 MHz minimum, and a quality factor (Q) of 55 at 0.252 MHz test frequency. The inductor operates reliably across a temperature range of -40°C to +105°C with a maximum temperature rise of 20°C at rated current, and features a shrinkable tube rated for 125°C and 600 V. This component is ideal for filtering, energy storage, and impedance matching in power conversion circuits where compact size and high inductance values are required.
