Gowanda’s SMRF1512S-154KS is a shielded epoxy-coated chip inductor designed for high reliability and performance in demanding applications. This component, part of the SMRF1512S series, is a COTS M83446/11 grade product, ensuring it meets commercial off-the-shelf standards with enhanced reliability. It features a compact design with dimensions of 3.94 × 3.175 × 3.56 mm and weighs just 0.12 grams, making it suitable for surface mount technology (SMT) applications. The inductor offers an inductance of 1500 µH, a direct current resistance (DCR) of 25 Ω, and a current rating of 0.044 A DC. It operates effectively within a frequency range, with a self-resonant frequency (SRF) of 1.6 MHz and a test frequency of 0.25 MHz, while maintaining a minimum quality factor (Q MIN) of 75. The device is designed to withstand dielectric withstanding voltages (DWV) of 200 and 500, with a tolerance of ±10%. It features lead (Pb) termination type, compliant with RoHS standards, and offers termination finishes of Sn63Pb37 and SnCu. The core is made of ferrite, and the component is shielded to minimize electromagnetic interference. It operates within a temperature range of -55°C to +125°C, has a moisture sensitivity level (MSL) of 1, and is available in tape and reel (T&R) packaging for efficient handling and installation.
