Gowanda’s SMRF1512S-222MS is a shielded epoxy-coated chip inductor designed for high reliability 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 performance. 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 space-constrained environments. The inductor offers an inductance of 22 µH, a DCR of 2.1 Ω, and a current rating of 0.15 A DC. It operates effectively within a frequency range, with an SRF of 23 MHz and a test frequency of 2.5 MHz, while maintaining a Q factor of at least 105. The component is designed to withstand a wide operating temperature range from -55°C to +125°C and is rated with a dielectric withstanding voltage of 200 to 500. It features a Pb, RoHS termination type with a Sn63Pb37, SnCu finish, and is mounted using SMT technology. The core is made of ferrite, and the product is shielded to minimize electromagnetic interference, packaged in tape and reel format for ease of use in automated assembly processes.
