Gowanda’s SMRF1512S-104KS is a shielded epoxy-coated chip inductor designed for high reliability in demanding applications. As part of the COTS M83446/11 series, it features a compact size with dimensions of 3.94 × 3.175 × 3.56 mm and a weight of 0.12 g. This surface-mount technology (SMT) component is suitable for COTS+ application grades, offering an inductance of 1000 µH and a direct current resistance (DCR) of 22 Ω. It supports a current rating of 0.047 A DC and a self-resonant frequency (SRF) of 2 MHz, tested at a frequency of 0.79 MHz with a minimum Q factor of 95. The device is designed to withstand dielectric withstanding voltages (DWV) of 200 and 500, with a tolerance of ±10%. It features Pb and RoHS-compliant terminations with Sn63Pb37 and SnCu finishes, utilizing a ferrite core for enhanced performance. The inductor is shielded and operates effectively within a temperature range of -55°C to +125°C, with a moisture sensitivity level (MSL) of 1, and is available in tape and reel (T&R) packaging for efficient handling and installation.
