Gowanda’s 22M274G is a high-quality, reliable electronic component designed for demanding applications. This molded unshielded RF coil weighs 1.7 grams and measures 14.224 × 5.461 × 5.461 mm. Part of the 22M series, it features through-hole technology (THT) mounting and is suitable for commercial off-the-shelf (COTS) applications. With an inductance of 2700 µH and a minimum Q factor of 70, it operates at a test frequency of 0.25 MHz. The coil has a DC resistance of 33 ohms and a self-resonant frequency of 1.8 MHz, with a current rating of 0.062 A DC. It can withstand dielectric withstanding voltages of 180 and 700, and offers a tolerance of ±2%. The termination type is lead-based with a Sn63Pb37 finish, and the core is made of powdered iron. It is not shielded, operates within a temperature range of -55°C to +105°C, and has a moisture sensitivity level (MSL) of 1. Packaged in tape and reel (T&R), it is also fungal inert, ensuring durability and reliability in various environments.
