Gowanda’s 21M121G is a high-quality molded unshielded RF coil designed for reliable performance in various applications. With a weight of 1.7 grams and dimensions of 14.224 × 5.588 × 5.588 mm, this component is part of the 21M series and features through-hole technology (THT) mounting. It is suitable for commercial off-the-shelf (COTS) applications, offering an inductance of 1.2 µH and a minimum Q factor of 40 at a test frequency of 7.9 MHz. The coil has a direct current resistance (DCR) of 0.19 ohms and a self-resonant frequency (SRF) of 180 MHz, with a current rating of 1.12 A DC. It can withstand dielectric withstanding voltages (DWV) of 1000 and 200 volts, with a tolerance of ±2%. The termination type is lead-based (Pb) with a Sn63Pb37 finish, and it features a phenolic core. The component is not shielded and operates within a temperature range of -55°C to +125°C. It is moisture sensitivity level (MSL) 1 rated, packaged in tape and reel (T&R), and is fungal inert.
