Gowanda’s SMRF1812S-181J is a high-quality molded shielded inductor designed for reliable performance in demanding applications. With a compact size of 4.2 × 3 × 2.9 mm and a weight of just 0.15 g, this inductor is ideal for space-constrained environments. It features a COTS+ application grade, ensuring suitability for commercial off-the-shelf applications. The inductor offers an inductance of 1.8 µH, a DCR of 0.182 Ω, and a current rating of 1.047 A DC, with a saturation current of 0.942 A DC. It operates effectively across a wide temperature range from -55°C to +125°C and is shielded to minimize electromagnetic interference. The SMRF1812S-181J is built with a ferrite core and has a Q MIN of 40, ensuring high performance at a test frequency of 7.9 MHz. It is packaged in tape and reel (T&R) format for easy handling and is fungal inert, making it suitable for various environments. The termination type is Pb with a Sn63Pb37 finish, and it meets MSL 1 standards for moisture sensitivity.
