Gowanda’s SMRF1512-561MS is an unshielded epoxy-coated chip inductor designed for high reliability in demanding applications. As part of the COTS M83446/10 series, it 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). This inductor offers an inductance of 5.6 µH, a DCR of 1.8 Ω, and a current rating of 0.16 A DC. It operates effectively within a frequency range, with a self-resonant frequency (SRF) of 40 MHz and a test frequency of 7.9 MHz, maintaining a minimum Q factor of 65. The component is built with a powdered iron core and is designed to withstand operating temperatures from -55°C to +125°C. It is compliant with Pb and RoHS standards, featuring a termination finish of Sn63Pb37 or SnCu, and is packaged in tape and reel (T&R) format for ease of use in automated assembly processes.
