Gowanda’s SMRF1512-182KS 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 18 µH with a direct current resistance (DCR) of 3.8 Ω and a current rating of 0.114 A DC. The inductor operates efficiently across a frequency range, with a self-resonant frequency (SRF) of 17 MHz and a test frequency of 2.5 MHz, ensuring a minimum quality factor (Q) of 60. It is built with a powdered iron core and features a termination type that is lead-based, RoHS compliant, with a finish of Sn63Pb37 or SnCu. The SMRF1512-182KS is designed to withstand extreme temperatures, operating between -55°C and +125°C, and is packaged in tape and reel (T&R) format for ease of handling and assembly.
