Gowanda’s 18M561M 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 5.6 µH and a minimum Q factor of 30, these coils operate at a test frequency of 7.9 MHz. They have a DC resistance of 0.28 ohms, a self-resonant frequency of 50 MHz, and a current rating of 0.645 A DC. The dielectric withstanding voltage is 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, with an operating temperature range from -55°C to +125°C and a moisture sensitivity level of 1. They are packaged in tape and reel format.
