Gowanda’s 8M391G 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 suitable for through-hole technology (THT) mounting and is classified under the Commercial Off-The-Shelf (COTS) application grade. The coil offers an inductance of 3.9 µH with a minimum Q factor of 50 at a test frequency of 7.9 MHz. It has a DC resistance of 1.5 ohms and a self-resonant frequency of 95 MHz, supporting a current rating of 0.178 A DC. The dielectric withstanding voltage is rated at 1000, 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 efficiently in temperatures ranging from -55°C to +105°C, the coil is fungal inert and comes in tape and reel packaging with a moisture sensitivity level of 1.
