Gowanda’s SMRF1812S-121MLF is a high-quality molded shielded inductor designed for reliable performance in demanding applications. Weighing just 0.15 grams and measuring 4.2 × 3 × 2.9 mm, this inductor is part of the SMRF1812S series and is suitable for surface mount technology (SMT). It is classified as COTS+ grade, ensuring it meets commercial off-the-shelf standards with enhanced reliability. The inductor offers an inductance of 1.2 µH with a direct current resistance (DCR) of 0.151 Ω and a current rating of 1.15 A DC. It features a saturation current of 1.164 A DC and a self-resonant frequency (SRF) of 112 MHz, tested at 7.9 MHz with a minimum Q factor of 40. The component has a tolerance of ±20% and is RoHS compliant with Sn100 termination finish. Constructed with a ferrite core and shielded for optimal performance, it operates within a temperature range of -55°C to +125°C and is rated MSL 1 for moisture sensitivity. Packaged in tape and reel (T&R) format, it is also fungal inert, making it suitable for a variety of electronic applications.
