Gowanda’s SMRF1512S-184MS 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 commercial off-the-shelf standards. With dimensions of 3.94 × 3.175 × 3.56 mm and a weight of 0.12 g, it is compact yet robust. It features an inductance of 1800 µH, a DCR of 27 Ω, and a current rating of 0.043 A DC. The inductor operates at a self-resonant frequency of 1.5 MHz and is tested at 0.25 MHz, with a minimum Q factor of 75. It supports a dielectric withstanding voltage of 200 to 500 and has a tolerance of ±20%. The SMT mounting type and Pb, RoHS termination with Sn63Pb37, SnCu finish make it versatile for various applications. The ferrite core and shielded design enhance performance, while the operating temperature range of -55°C to +125°C and MSL 1 rating ensure reliability in extreme conditions. It is available in tape and reel packaging for efficient handling.
