SRR1210-390M is a shielded surface-mount power inductor from the Bourns SRR1210 series designed for DC/DC converter input/output filtering and power supply applications. The device features an inductance of 39 µH (±20% tolerance) with a saturation current of 13 A and an RMS current rating of 3.5 A, operating at a self-resonant frequency of 4.5 MHz. It is constructed with a ferrite core (DR & RI materials) and enameled copper wire with matte tin terminal coating, housed in a compact 12.0 mm × 12.0 mm × 10.0 mm maximum package. The inductor operates reliably across a temperature range of -40°C to +125°C with a typical temperature rise of 40°C at rated current, and features RoHS compliance and Moisture Sensitivity Level 1. This component is ideal for portable communication equipment, camcorders, LCD TVs, and other power conversion applications requiring compact, high-performance filtering.
