Gowanda’s SMRF1812-180M is a high-quality molded unshielded inductor designed for demanding applications, featuring a compact size with dimensions of 4.064 × 3 × 2.9 mm and a weight of 0.15 g. This COTS M83446/39 compliant component is suitable for surface mount technology (SMT) and is crafted for COTS+ application grade. It offers an inductance of 0.18 µH with a direct current resistance (DCR) of 0.35 Ω and a current rating of 0.757 A DC. The inductor operates efficiently with a self-resonant frequency (SRF) of 400 MHz and a test frequency of 25 MHz, maintaining a minimum Q factor of 40 and a tolerance of ±20%. Constructed with a powdered iron core, it is designed to function within a wide operating temperature range of -55°C to +125°C. The SMRF1812-180M is lead-terminated with a Sn63Pb37 finish, ensuring reliable performance, and is packaged in tape and reel (T&R) format. It is also fungal inert, making it suitable for various environmental conditions.
