SRR4818A-120M is a shielded power inductor from Bourns' SRR4818A series, featuring a 12 µH inductance value with ±20% tolerance and a self-resonant frequency of 37 MHz. The inductor exhibits a typical DC resistance of 132.2 mO with a maximum of 170.0 mO, and supports rated currents of 1.30 A (Irms1) and 1.60 A (Irms2), with a saturation current of 0.95 A. The device is constructed with a ferrite core and enameled copper wire, housed in a compact surface-mount package with tin-plated terminals, and operates reliably across a temperature range of -40°C to +150°C. This inductor is AEC-Q200 qualified, RoHS compliant, and halogen-free, making it ideal for automotive systems including driver assistance, infotainment, and lighting applications, as well as DC/DC converters and power supply circuits where space efficiency and thermal stability are critical.
