Gowanda’s 15M121K is a high-quality, molded unshielded RF coil designed for reliable performance in various electronic 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) for easy mounting. It is suitable for commercial off-the-shelf (COTS) applications, offering an inductance of 1.2 µH with a minimum Q factor of 33 at a test frequency of 7.9 MHz. The coil has a DC resistance of 0.42 ohms and a self-resonant frequency of 180 MHz, with a current rating of 0.65 A DC. It can withstand a dielectric withstanding voltage (DWV) of 1000 volts and operates within a temperature range of -55°C to +125°C. The component is lead-terminated with a Sn63Pb37 finish and features a phenolic core. It is fungal inert, has a moisture sensitivity level (MSL) of 1, and is available in tape and reel (T&R) packaging.
