RLB0914-821K is a radial lead inductor from Bourns' RLB Series designed for high-current power supply and DC/DC converter circuits. The device features an 820 µH inductance (±10%) with a ferrite DR core and enameled copper wire construction, delivering a quality factor (Q) of 20 at 0.796 MHz test frequency. It exhibits a self-resonant frequency (SRF) of 1.5 MHz minimum and a DC resistance (RDC) of 1.8 mO maximum, with a typical RMS current rating of 0.46 A and saturation current of 0.83 A. The inductor operates reliably across -40°C to +125°C and features Cu/Sn terminals with a shrinkable tube rated for 125°C and 600 V. This component is ideal for power supplies, DC/DC converters, and general-purpose inductive filtering applications requiring compact, high-performance energy storage.
