Gowanda’s 15M681G is a high-quality molded unshielded RF coil designed for reliable performance in various applications. Weighing 0.65 grams and measuring 9.525 × 3.962 × 3.962 mm, this component is part of the 15M series and features through-hole technology (THT) mounting. It is suitable for commercial off-the-shelf (COTS) applications, offering an inductance of 6.8 µH with a minimum Q factor of 50 at a test frequency of 7.9 MHz. The coil has a direct current resistance (DCR) of 0.5 Ω and a self-resonant frequency (SRF) of 55 MHz, with a current rating of 0.395 A DC. It can withstand a dielectric withstanding voltage (DWV) of 1000 volts and maintains a tolerance of ±3%. The termination type is lead-based with a Sn63Pb37 finish, and the core is made of powdered iron. Operating efficiently between -55°C and +125°C, the component is rated with a moisture sensitivity level (MSL) of 1 and is packaged in tape and reel (T&R) format. Additionally, it is fungal inert, ensuring durability and reliability in demanding environments.
