Gowanda’s 8M681G 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 Series 8M. 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 6.8 µH and a minimum Q factor of 55, it operates at a test frequency of 7.9 MHz. The coil has a direct current resistance (DCR) of 3.2 ohms and a self-resonant frequency (SRF) of 69 MHz, supporting a current rating of 0.122 A DC. It is designed to withstand dielectric withstanding voltages (DWV) 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 component 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.
