Gowanda’s SMRF1812S-471KLF is a high-quality molded shielded inductor designed for reliable performance in various applications. With a compact weight of 0.15 g and dimensions of 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+ grade applications, offering an inductance of 4.7 µH, a direct current resistance (DCR) of 0.312 Ω, and a current rating of 0.8 A DC. The inductor also boasts a saturation current of 0.582 A DC and a self-resonant frequency (SRF) of 35 MHz, tested at 7.9 MHz with a minimum Q factor of 40. It has a tolerance of ±10% and is RoHS compliant with Sn100 termination finish. The ferrite core and shielded design ensure optimal performance across a wide operating temperature range of -55°C to +125°C. With a moisture sensitivity level (MSL) of 1 and packaged in tape and reel (T&R), this inductor is also fungal inert, making it a reliable choice for demanding environments.
