Gowanda’s 8M821G is a high-quality, reliable molded unshielded RF coil designed for a variety of applications. With a compact weight of 0.25 g and dimensions of 5.08 × 1.98 × 1.98 mm, this component is part of the 8M series and features through-hole technology (THT) mounting. It is suitable for commercial off-the-shelf (COTS) applications, offering an inductance of 8.2 µH and a minimum Q factor of 45 at a test frequency of 7.9 MHz. The coil has a DC resistance of 4.4 Ω, a self-resonant frequency of 52 MHz, and a current rating of 0.104 A DC. It is designed to withstand dielectric withstanding voltages of 1000 and 200, with a tolerance of ±2%. The termination type is lead-based with a Sn63Pb37 finish, and the core is made of powdered iron. Operating within a temperature range of -55°C to +105°C, the 8M821G is rated MSL 1 and is packaged in tape and reel (T&R) format. Additionally, it is fungal inert, ensuring durability and reliability in various environments.
