Gowanda’s 8M221K is a high-quality molded unshielded RF coil designed for reliable performance in various electronic applications. Weighing just 0.25 grams, this component features compact dimensions of 5.08 × 1.98 × 1.98 mm and is part of the 8M series. It is tailored for through-hole technology (THT) mounting and is suitable for commercial off-the-shelf (COTS) applications. With an inductance of 2.2 µH and a minimum Q factor of 45, it operates efficiently at a test frequency of 7.9 MHz. The coil has a direct current resistance (DCR) of 0.72 Ω and a self-resonant frequency (SRF) of 130 MHz, supporting a current rating of 0.257 A DC. It is designed to withstand dielectric withstanding voltages (DWV) of 1000 and 200, with a tolerance of ±10%. The termination type is lead-based with a Sn63Pb37 finish, and it utilizes a powdered iron core. Operating within a temperature range of -55°C to +105°C, the 8M221K 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.
