Gowanda’s 28M102K is a high-quality molded unshielded RF coil designed for reliable performance in various electronic applications. With a weight of 2.65 grams and dimensions of 22.86 × 7.137 × 7.137 mm, this component is part of the 28M series and features through-hole technology (THT) for mounting. It is suitable for commercial off-the-shelf (COTS) applications, offering an inductance of 10 µH and a minimum Q factor of 60 at a test frequency of 7.9 MHz. The coil has a direct current resistance (DCR) of 1.9 ohms and a self-resonant frequency (SRF) of 60 MHz, with a current rating of 0.46 A DC. It can withstand dielectric withstanding voltages (DWV) of 1000 and 200, with a tolerance of ±10%. The termination type is lead-based (Pb) with a finish of Sn63Pb37, and it features a phenolic core. Operating efficiently in temperatures ranging from -55°C to +105°C, the component is rated at moisture sensitivity level (MSL) 1 and is packaged in tape and reel (T&R) format. Additionally, it is fungal inert, ensuring durability and reliability in various environments.
