RLB9012-122KL is a radial leaded inductor designed for power supply and DC/DC converter applications. It features an inductance of 1200 µH ± 10% measured at 1 kHz, with a Q reference of 15 at a test frequency of 0.252 MHz. The inductor has a maximum DC resistance of 3.9 ohms and supports a maximum rated DC current of 0.48 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. This RoHS compliant component is ideal for general-purpose filtering and energy storage in power electronics.
