Gowanda’s 18M220K is a molded unshielded RF coil designed for high-quality, reliable performance in electronic applications. Weighing 0.95 grams and measuring 11.125 × 4.775 × 4.775 mm, this component is part of the 18M series and features through-hole technology (THT) mounting. It is suitable for commercial off-the-shelf (COTS) applications, offering an inductance of 0.22 µH with a minimum Q factor of 50 at a test frequency of 25 MHz. The coil has a DC resistance of 0.035 ohms, a self-resonant frequency of 415 MHz, and a current rating of 2.8 A DC. It can withstand a dielectric withstanding voltage (DWV) of 200 volts and operates within a temperature range of -55°C to +125°C. With a tolerance of ±10%, the coil features leaded (Pb) termination with a Sn63Pb37 finish and a phenolic core. It is packaged in tape and reel (T&R) format, has a moisture sensitivity level (MSL) of 1, and is fungal inert.
