Gowanda’s SMRF1812S-473K 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, offering an inductance of 470 µH with a direct current resistance (DCR) of 17 Ω. The inductor supports a current rating of 0.122 A DC and a saturation current of 0.048 A DC, with a self-resonant frequency (SRF) of 3.3 MHz. It is tested at a frequency of 0.79 MHz and has a minimum quality factor (Q MIN) of 40, with a tolerance of ±10%. The termination type is lead-based (Pb) with a finish of Sn63Pb37, and it features a ferrite core with shielding. The operating temperature range is from -55°C to +125°C, and it has a moisture sensitivity level (MSL) of 1. Packaged in tape and reel (T&R), it is also fungal inert, ensuring durability and performance in various environments.
