Gowanda’s SMRF1812-270K is a high-quality, reliable molded unshielded inductor designed for COTS applications, adhering to the M83446/39 standard. This component weighs 0.15 grams and measures 4.064 × 3 × 2.9 mm, making it suitable for surface mount technology (SMT). It features an inductance of 0.27 µH, a direct current resistance (DCR) of 0.45 Ω, and a current rating of 0.668 A DC. The inductor operates at a self-resonant frequency (SRF) of 300 MHz and is tested at 25 MHz, with a minimum Q factor of 40 and a tolerance of ±10%. Its powdered iron core and Sn63Pb37 termination finish ensure durability, while its operating temperature range of -55°C to +125°C and MSL 1 rating highlight its robustness. The component is packaged in tape and reel (T&R) format and is fungal inert, making it ideal for demanding environments.
