Gowanda’s SMRF1812S-181M is a high-quality molded shielded inductor designed for reliable performance in electronic applications. With a compact size of 4.2 × 3 × 2.9 mm and a weight of 0.15 g, this inductor is ideal for space-constrained environments. It features a surface-mount technology (SMT) mounting type and is part of the SMRF1812S series, suitable for COTS+ application grade. 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 within a frequency range, with an SRF of 60 MHz and a test frequency of 7.9 MHz, ensuring a minimum Q factor of 40. The component is built with a ferrite core and is shielded to minimize electromagnetic interference. It can operate in extreme temperatures ranging from -55°C to +125°C and has a moisture sensitivity level (MSL) of 1. The inductor is packaged in tape and reel (T&R) format, is fungal inert, and features a Pb termination type with a Sn63Pb37 finish.
