8M391K

Gowanda’s 8M391K 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 as a commercial off-the-shelf (COTS) application grade. With an inductance of 3.9 µH and a minimum Q factor of 50, it operates at a test frequency of 7.9 MHz. The coil has a direct current resistance (DCR) of 1.5 ohms and a self-resonant frequency (SRF) of 95 MHz, supporting a current rating of 0.178 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 (Pb) with a Sn63Pb37 finish, and it utilizes a powdered iron core. Operating efficiently in temperatures ranging from -55°C to +105°C, it is rated at moisture sensitivity level (MSL) 1 and is packaged in tape and reel (T&R) format. Additionally, the component is fungal inert, ensuring durability in various environments.
