Gowanda’s SMRF1512-681KS is an unshielded epoxy-coated chip inductor designed for high reliability in electronic 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. This surface-mount technology (SMT) component is ideal for COTS+ application grades, offering an inductance of 6.8 µH and a direct current resistance (DCR) of 2.4 Ω. It supports a current rating of 0.14 A DC and a self-resonant frequency (SRF) of 37 MHz, tested at 7.9 MHz with a minimum Q factor of 65. The inductor maintains a tolerance of ±10% and is constructed with a powdered iron core. It operates efficiently across a temperature range of -55°C to +125°C and is compliant with MSL 1 standards. The termination type is Pb, RoHS, with a finish of Sn63Pb37 or SnCu, and it is available in tape and reel (T&R) packaging.
