Gowanda’s 18M821M Molded Unshielded RF Coils are high-quality electronic components designed for reliable performance in various applications. These coils weigh 0.95 grams and have dimensions of 11.125 × 4.775 × 4.775 mm. They belong to the 18M series and are mounted using Through-Hole Technology (THT). Suitable for Commercial Off-The-Shelf (COTS) applications, they offer an inductance of 8.2 µH with a minimum Q factor of 30 at a test frequency of 7.9 MHz. The coils have a DC resistance of 0.44 ohms and a self-resonant frequency of 48 MHz, with a current rating of 0.54 A DC. They are designed to withstand a dielectric withstanding voltage of 200 volts 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 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, with the added benefit of being fungal inert.
