Gowanda’s 18M220M 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 0.22 µH and a minimum Q factor of 50, they operate at a test frequency of 25 MHz. The coils have a DC resistance of 0.035 ohms and a self-resonant frequency of 415 MHz, supporting a current rating of 2.8 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 is made of phenolic material. These components are not shielded, operate within a temperature range of -55°C to +125°C, and have a moisture sensitivity level of 1. They are packaged in tape and reel format and are fungal inert.
