Gowanda’s SMRF1512S-330K 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 weighs just 0.12 g. This surface-mount technology (SMT) component is ideal for COTS+ application grades, offering an inductance of 0.33 µH with a DCR of 0.05 Ω and a current rating of 0.75 A DC. It operates efficiently with a self-resonant frequency (SRF) of 310 MHz and a test frequency of 25 MHz, maintaining a Q factor of at least 93. The inductor is designed to withstand a dielectric withstanding voltage (DWV) of 200 to 500 volts and has a tolerance of ±10%. It features RoHS-compliant gold termination and a ferrite core, ensuring robust performance in temperatures ranging from -55°C to +125°C. With a moisture sensitivity level (MSL) of 1, it is packaged in tape and reel (T&R) for easy handling and integration.
