Gowanda’s SMRF1812-122JLF is a high-quality molded unshielded inductor designed for demanding applications, featuring a compact size with dimensions of 4.064 × 3 × 2.9 mm and a weight of 0.15 g. This COTS M83446/39 compliant component is suitable for surface mount technology (SMT) and offers an inductance of 12 µH with a DCR of 2 Ω. It supports a current rating of 0.317 A DC and has a self-resonant frequency (SRF) of 18 MHz, tested at a frequency of 2.5 MHz. With a minimum Q factor of 50 and a tolerance of ±5%, it ensures reliable performance across a wide operating temperature range of -55°C to +125°C. The inductor features RoHS-compliant Sn100 termination and is made with a ferrite core, though it is not shielded. It is packaged in tape and reel (T&R) format, has a moisture sensitivity level (MSL) of 1, and is fungal inert, making it ideal for high-reliability applications.
