RLB9012-182KL is a radial leaded inductor from the Bourns RLB9012 series, designed for general-purpose filtering and energy storage applications. It features an inductance of 1800 µH ± 10% measured at 1 kHz, with a Q reference of 15 at a test frequency of 0.252 MHz and a minimum self-resonant frequency (SRF) of 1.00 MHz. The inductor has a maximum DC resistance (RDC) of 5.3 ohms and supports a maximum rated DC current (IDC) of 0.39 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 well-suited for power supplies, DC/DC converters, and general-use applications requiring reliable inductive performance.
