RLB9012-220KL is a radial leaded inductor designed for power supply filtering and DC/DC converter applications. It features a 22 µH inductance with ±10% tolerance measured at 1 kHz, a Q factor of 40 at 2.52 MHz test frequency, and a self-resonant frequency (SRF) minimum of 9.20 MHz. The inductor has a maximum DC resistance of 0.070 ohms and supports a maximum rated DC current of 2.40 A with only 5% inductance drop. Constructed with a ferrite DR core and enameled copper wire, it operates over a temperature range of -55°C to +125°C, making it suitable for demanding industrial and commercial power applications.
