18M221M

Gowanda’s 18M221M Molded Unshielded RF Coils are a testament to their commitment to high-quality electronic components. These coils weigh 0.95 grams and have dimensions of 11.125 × 4.775 × 4.775 mm. Part of the 18M series, they are designed for through-hole technology (THT) mounting and are suitable for commercial off-the-shelf (COTS) applications. With an inductance of 2.2 µH and a minimum Q factor of 30, these coils operate at a test frequency of 7.9 MHz. They feature a DC resistance of 0.97 ohms and a self-resonant frequency of 140 MHz, with a current rating of 0.505 A DC. The dielectric withstanding voltage is 200, and they have a tolerance of ±20%. The termination type is lead-based with a Sn63Pb37 finish, and the core is made of phenolic material. These coils are not shielded but are designed to operate in temperatures ranging from -55°C to +125°C, with a moisture sensitivity level of 1. Packaged in tape and reel (T&R) format, they are also fungal inert, ensuring reliability in various environments.
