Gowanda’s 28M103M Molded Unshielded RF Coils are high-quality electronic components designed for reliable performance in various applications. These coils feature a compact design with dimensions of 22.86 × 7.137 × 7.137 mm and a weight of 2.65 g. They belong to the 28M series and are mounted using Through-Hole Technology (THT). With an inductance of 100 µH and a minimum Q factor of 75, these coils operate at a test frequency of 2.5 MHz. They have a DC resistance of 2.5 Ω and a self-resonant frequency of 12 MHz, supporting a current rating of 0.245 A DC. The dielectric withstanding voltage is rated at 1000, 200, and they offer a tolerance of ±20%. The termination type is lead-based with a Sn63Pb37 finish, and the core is made of powdered iron. These coils are not shielded but are fungal inert and can operate in temperatures ranging from -55°C to +125°C. They have a moisture sensitivity level of 1 and are packaged in tape and reel format.
