Gowanda’s 17S221M is a high-quality molded shielded RF coil designed for reliable performance in various applications. Weighing 0.7 grams, this component features dimensions of 10.414 × 4.115 × 4.115 mm and belongs to the 17S series. It is suitable for through-hole technology (THT) mounting and is classified under commercial off-the-shelf (COTS) application grade. The coil offers an inductance of 2.2 µH with a minimum Q factor of 44, tested at a frequency of 7.9 MHz. It has a direct current resistance (DCR) of 0.19 Ω and a self-resonant frequency (SRF) of 100 MHz, with a current rating of 0.65 A DC. The dielectric withstanding voltage (DWV) is 1000, and it maintains 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, has a moisture sensitivity level (MSL) of 1, and is available in tape and reel (T&R) packaging. However, it is not fungal inert.
