Gowanda’s 28M392M Molded Unshielded RF Coils are high-quality electronic components designed for reliable performance in various applications. These coils weigh 2.65 grams and have dimensions of 22.86 × 7.137 × 7.137 mm. Part of the 28M series, they feature a through-hole mounting type and are suitable for commercial off-the-shelf (COTS) applications. With an inductance of 39 µH and a minimum Q factor of 55, they operate at a test frequency of 2.5 MHz. The coils have a DC resistance of 0.65 ohms, a self-resonant frequency of 18 MHz, and a current rating of 0.485 A DC. They can withstand a dielectric withstanding voltage of 1000, 200 and have a tolerance of ±20%. The termination type is lead-based with a Sn63Pb37 finish, and the core is made of powdered iron. These components are not shielded, operate within a temperature range of -55°C to +125°C, and have a moisture sensitivity level of 1. Packaged in tape and reel, they are also fungal inert.
