Gowanda’s 8M821K is a high-quality, reliable molded unshielded RF coil designed for 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 suitable for through-hole technology (THT) mounting and is classified under the Commercial Off-The-Shelf (COTS) application grade. With an inductance of 8.2 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 4.4 ohms and a self-resonant frequency (SRF) of 52 MHz, supporting a current rating of 0.104 A DC. It is designed to withstand dielectric withstanding voltages (DWV) of 1000 and 200 volts, 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 8M821K is fungal inert and has a moisture sensitivity level (MSL) of 1, making it ideal for various environments. It is available in tape and reel (T&R) packaging for convenient handling and installation.
