Gowanda’s SMRF1812S-472K is a high-quality molded shielded inductor designed for reliable performance in demanding applications. Weighing just 0.15 grams and measuring 4.2 × 3 × 2.9 mm, this inductor is part of the SMRF1812S series and features surface mount technology (SMT) for easy integration. It is suitable for COTS+ application grades, offering an inductance of 47 µH with a direct current resistance (DCR) of 2.6 Ω. The component supports a current rating of 0.277 A DC and a saturation current of 0.159 A DC, with a self-resonant frequency (SRF) of 9 MHz and a test frequency of 2.5 MHz. With a minimum Q factor of 50 and a tolerance of ±10%, it ensures precision and efficiency. The inductor is constructed with a ferrite core and features a lead-based termination type with a Sn63Pb37 finish. It operates effectively within a temperature range of -55°C to +125°C, is moisture sensitivity level (MSL) 1, and is packaged in tape and reel (T&R) format. Additionally, it is fungal inert, making it suitable for various environments.
