Gowanda’s 28M392MLF is a high-quality, reliable electronic component designed for demanding applications. This molded unshielded RF coil weighs 2.65 grams and measures 22.86 × 7.137 × 7.137 mm. Part of the 28M series, it features through-hole technology (THT) mounting and is suitable for commercial off-the-shelf (COTS) applications. With an inductance of 39 µH and a minimum Q factor of 55, it operates at a test frequency of 2.5 MHz. The coil has a DC resistance of 0.65 Ω, a self-resonant frequency of 18 MHz, and a current rating of 0.485 A DC. It is designed to withstand dielectric withstanding voltages of 1000 and 200, with a tolerance of ±20%. The termination type is RoHS compliant with a Sn/Cu finish, and it uses a powdered iron core. The component is not shielded and operates within a temperature range of -55°C to +125°C. It has a moisture sensitivity level of 1 and is packaged in tape and reel (T&R) format. Additionally, it is fungal inert, ensuring durability and reliability in various environments.
