Gowanda’s 28M681MLF is a high-quality, reliable molded unshielded RF coil designed for various electronic applications. This component weighs 2.65 grams and measures 22.86 × 7.137 × 7.137 mm, making it suitable for through-hole technology (THT) mounting. It belongs to the 28M series and is classified as a Commercial Off-The-Shelf (COTS) application grade. With an inductance of 6.8 µH and a minimum Q factor of 60, it operates efficiently at a test frequency of 7.9 MHz. The coil has a DC resistance of 1.05 ohms and a self-resonant frequency of 75 MHz, supporting a current rating of 0.635 A DC. It features a dielectric withstanding voltage (DWV) of 1000, 200 and a tolerance of ±20%. The termination is RoHS compliant with a Sn/Cu finish, and the core is made of phenolic material. Operating within a temperature range of -55°C to +105°C, it is fungal inert and comes in tape and reel (T&R) packaging with a moisture sensitivity level (MSL) of 1.
