Gowanda’s SMRF1512S-273K is a shielded epoxy-coated chip inductor designed for high reliability in demanding applications. This COTS M83446/11 component features a compact size with dimensions of 3.94 × 3.175 × 3.56 mm and weighs just 0.12 g. It is suitable for surface mount technology (SMT) and offers an inductance of 270 µH with a direct current resistance (DCR) of 8.1 Ω. The inductor supports a current rating of 0.078 A DC and a self-resonant frequency (SRF) of 5.2 MHz, tested at a frequency of 0.79 MHz. With a minimum quality factor (Q MIN) of 85 and dielectric withstanding voltage (DWV) options of 200 and 500, it ensures performance stability. The product is RoHS compliant with gold termination finish and operates efficiently across a temperature range of -55°C to +125°C. It is packaged in tape and reel (T&R) format, making it ideal for automated assembly processes.
