Gowanda’s SMRF1812-823G 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 component is part of the SMRF1812 series and is suitable for surface mount technology (SMT) applications, specifically catering to COTS+ grade requirements. It offers an inductance of 820 µH with a low direct current resistance (DCR) of 35 Ω and a current rating of 0.076 A DC. The inductor operates effectively within a frequency range, with a self-resonant frequency (SRF) of 2.5 MHz and a test frequency of 0.79 MHz, ensuring a minimum quality factor (Q MIN) of 30. It is built with a ferrite core and features a lead (Pb) termination type with a Sn63Pb37 finish. The component is designed to withstand extreme temperatures, operating reliably from -55°C to +125°C, and is packaged in tape and reel (T&R) format. Additionally, it is fungal inert, making it suitable for various environmental conditions.
