RLB0812-102KL is a radial lead inductor from Bourns' RLB Series designed for high-current power supply and DC/DC converter circuits. The device features a ferrite DR core with enameled copper wire windings and Cu/Sn terminals, delivering an inductance of 1000 µH ± 10% with a maximum DC resistance of 3.9 O and a maximum DC current rating of 120 mA. Operating across a temperature range of -40°C to +125°C with a self-resonant frequency of 1.4 MHz, this inductor provides reliable performance in demanding power conversion applications. The RoHS-compliant construction and shrinkable tube insulation rated to 125°C and 600 V make it suitable for general-purpose power management, energy storage, and filtering in industrial and consumer electronics.
