Gowanda’s SMRF1812S-333M 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 inductor is part of the SMRF1812S series and is suitable for surface mount technology (SMT). It features a 330 µH inductance with a DCR of 9.69 Ω and a current rating of 0.144 A DC. The saturation current is 0.057 A DC, and it has a self-resonant frequency (SRF) of 3.7 MHz, tested at 0.79 MHz with a minimum Q factor of 40. The inductor has a tolerance of ±20% and uses a Pb termination type with a Sn63Pb37 finish. It is constructed with a ferrite core and is shielded, operating effectively within a temperature range of -55°C to +125°C. The product is rated at MSL 1, packaged in tape and reel (T&R), and is fungal inert, making it ideal for COTS+ grade applications.
