Gowanda’s SMRF1812S-471M is a molded shielded inductor designed for high reliability in electronic applications. Weighing 0.15 grams and measuring 4.2 × 3 × 2.9 mm, this component is part of the SMRF1812S series and is suitable for surface mount technology (SMT). It is classified as COTS+ grade, ensuring enhanced performance for commercial off-the-shelf applications. The inductor features an inductance of 4.7 µH, a direct current resistance (DCR) of 0.312 Ω, and a current rating of 0.8 A DC, with a saturation current of 0.582 A DC. It operates effectively within a frequency range, with a self-resonant frequency (SRF) of 35 MHz and a test frequency of 7.9 MHz, maintaining a minimum Q factor of 40. The component offers a tolerance of ±20% and utilizes a lead-based termination type with a Sn63Pb37 finish. Constructed with a ferrite core and shielded design, it is capable of operating in temperatures ranging from -55°C to +125°C and is rated at moisture sensitivity level (MSL) 1. Packaged in tape and reel (T&R) format, it is also fungal inert, making it suitable for various demanding environments.
