Gowanda’s SMRF1512S-683MS is a shielded epoxy-coated chip inductor designed for high reliability in demanding applications. This COTS M83446/11 grade 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 direct current resistance (DCR) of 12 Ω and a current rating of 0.064 A DC. The inductor operates efficiently with a self-resonant frequency (SRF) of 2.3 MHz and a test frequency of 0.79 MHz, ensuring a minimum Q factor of 100. It is designed to withstand dielectric withstanding voltages (DWV) of 200 and 500, with a tolerance of ±20%. The termination type is Pb, RoHS compliant, with a termination finish of Sn63Pb37 or SnCu. The ferrite core and shielded design enhance performance, while the operating temperature range of -55°C to +125°C and moisture sensitivity level (MSL) of 1 ensure durability and reliability. The product is available in tape and reel (T&R) packaging.
