Gowanda’s SMRF1512S-392K is a shielded epoxy-coated chip inductor designed for high reliability in demanding applications. This COTS M83446/11 compliant component features a compact size with dimensions of 3.94 × 3.175 × 3.56 mm and a weight of 0.12 g, making it suitable for surface mount technology (SMT). It offers an inductance of 39 µH with a DCR of 3.1 Ω and a current rating of 0.125 A DC. The inductor operates effectively across a frequency range, with a self-resonant frequency (SRF) of 17 MHz and a test frequency of 2.5 MHz, ensuring a Q factor of at least 120. It is designed to withstand a dielectric withstanding voltage (DWV) of 200 to 500 volts and maintains performance across a wide operating temperature range from -55°C to +125°C. The product is RoHS compliant with gold termination finish and features a ferrite core for enhanced shielding. Packaged in tape and reel (T&R) format, it is ideal for applications requiring robust and reliable performance.
