Gowanda’s SMRF1512-181K is an unshielded epoxy-coated chip inductor designed for high reliability in demanding applications. This COTS M83446/10 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 1.8 µH with a DCR of 0.72 Ω and a current rating of 0.26 A DC. The inductor operates efficiently with a self-resonant frequency (SRF) of 100 MHz and a test frequency of 7.9 MHz, ensuring a Q MIN of 65. It is built with a powdered iron core and has a tolerance of ±10%. The termination is RoHS compliant with an Au finish, and it is capable of operating in temperatures ranging from -55°C to +125°C. With a moisture sensitivity level (MSL) of 1, it is packaged in tape and reel (T&R) for ease of handling and integration.
