Gowanda’s 18M121M 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. Part of the 18M series, they feature a through-hole mounting type and are suitable for commercial off-the-shelf (COTS) applications. With an inductance of 1.2 µH and a minimum Q factor of 30, they operate at a test frequency of 7.9 MHz. The coils have a DC resistance of 0.4 ohms and a self-resonant frequency of 180 MHz, supporting a current rating of 0.785 A DC. They are designed with a dielectric withstanding voltage of 200 and a tolerance of ±20%. The termination type is lead-based with a Sn63Pb37 finish, and the core material is phenolic. These coils are not shielded and can operate in temperatures ranging from -55°C to +125°C. They have a moisture sensitivity level of 1, are packaged in tape and reel, and are fungal inert.
