Gowanda’s SMRF1512-683KS is an unshielded epoxy-coated chip inductor designed for high reliability in demanding applications. As part of the COTS M83446/10 series, this component features a compact size with dimensions of 3.94 × 3.175 × 3.56 mm and a weight of 0.12 g, making it suitable for surface mount technology (SMT). It offers an inductance of 680 µH with a DCR of 55 Ω and a current rating of 0.03 A DC. The inductor operates effectively within a frequency range, with a self-resonant frequency (SRF) of 1.9 MHz and a test frequency of 0.79 MHz, ensuring a minimum Q factor of 35. It is built with a powdered iron core and features a termination type that is Pb, RoHS compliant, with a termination finish of Sn63Pb37 or SnCu. The SMRF1512-683KS is designed to withstand operating temperatures from -55°C to +125°C and is packaged in tape and reel (T&R) format, with a moisture sensitivity level (MSL) of 1, making it ideal for commercial off-the-shelf (COTS) applications.
