Gowanda’s 8M221J is a high-quality molded unshielded RF coil designed for reliable performance in various electronic applications. Weighing just 0.25 grams and measuring 5.08 × 1.98 × 1.98 mm, this component is part of the 8M series and features through-hole technology (THT) for easy mounting. It is suitable for commercial off-the-shelf (COTS) applications, offering an inductance of 2.2 µH with a minimum Q factor of 45 at a test frequency of 7.9 MHz. The coil has a direct current resistance (DCR) of 0.72 ohms and a self-resonant frequency (SRF) of 130 MHz, with a current rating of 0.257 A DC. It is built with a powdered iron core and operates effectively within a temperature range of -55°C to +105°C. The component is rated with a dielectric withstanding voltage (DWV) of 1000, 200, and features a termination type of Pb with a Sn63Pb37 finish. It is packaged in tape and reel (T&R) format, is fungal inert, and has a moisture sensitivity level (MSL) of 1, ensuring durability and reliability in demanding environments.
