Gowanda’s SMRF1512S-474M is a shielded epoxy-coated chip inductor designed for high reliability in demanding applications. This component, part of the SMRF1512S series, is a COTS M83446/11 grade product, ensuring it meets stringent commercial off-the-shelf standards. With a compact size of 3.94 × 3.175 × 3.56 mm and a weight of just 0.12 g, it is ideal for space-constrained environments. The inductor features a 4700 µH inductance with a DCR of 70 Ω and a current rating of 0.026 A DC. It operates effectively across a wide temperature range from -55°C to +125°C and is RoHS compliant with gold termination finish. The component is designed for surface mount technology (SMT) and comes in tape and reel packaging, making it suitable for automated assembly processes. Its ferrite core and shielding enhance performance by minimizing electromagnetic interference, while its high Q factor of 75 ensures efficient energy storage and transfer.
