Gowanda’s 17S821M is a high-quality molded shielded RF coil designed for reliable performance in various electronic applications. Weighing 0.7 grams and measuring 10.414 × 4.115 × 4.115 mm, this component is part of the 17S series and features through-hole technology (THT) mounting. It is suitable for commercial off-the-shelf (COTS) applications, offering an inductance of 8.2 µH with a minimum Q factor of 50 at a test frequency of 7.9 MHz. The coil has a DC resistance of 1.32 ohms and a self-resonant frequency of 50 MHz, with a current rating of 0.25 A DC. It can withstand a dielectric withstanding voltage (DWV) of 1000 volts and has a tolerance of ±20%. The termination type is lead-based with a Sn63Pb37 finish, and the core is made of powdered iron, providing effective shielding. It operates within a temperature range of -55°C to +105°C and has a moisture sensitivity level (MSL) of 1. The product is packaged in tape and reel (T&R) format, though it is not fungal inert.
