RLB9012-4R7ML is a radial leaded inductor designed for power supply and DC/DC converter applications. It features an inductance of 4.7 µH ± 20% measured at 1 kHz, with a Q factor reference of 20 at a test frequency of 7.96 MHz. The inductor has a self-resonant frequency (SRF) minimum of 51.00 MHz, a maximum DC resistance (RDC) of 0.030 ohms, and supports a maximum rated DC current (IDC) of 4.60 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 use in power electronics where reliable inductance and low DC resistance are required.
