Gowanda’s SMRF1512S-124KS is a shielded epoxy-coated chip inductor designed for high reliability in demanding applications. As part of the COTS M83446/11 series, this component features a compact size with dimensions of 3.94 × 3.175 × 3.56 mm and a weight of 0.12 g. It is suitable for surface mount technology (SMT) and offers an inductance of 1200 µH with a DCR of 24 Ω. The inductor supports a current rating of 0.045 A DC and operates with a self-resonant frequency (SRF) of 1.7 MHz. It is tested at a frequency of 0.25 MHz and boasts a minimum Q factor of 75. The device is built to withstand dielectric withstanding voltages (DWV) of 200 and 500, with a tolerance of ±10%. It features Pb and RoHS-compliant terminations with finishes of Sn63Pb37 and SnCu. Constructed with a ferrite core and shielded for enhanced performance, it operates effectively within a temperature range of -55°C to +125°C and has a moisture sensitivity level (MSL) of 1. Packaged in tape and reel (T&R), it is ideal for commercial off-the-shelf (COTS+) applications.
