Gowanda’s 28M271M Molded Unshielded RF Coils are high-quality electronic components designed for reliable performance in various applications. These coils weigh 2.65 grams and have dimensions of 22.86 × 7.137 × 7.137 mm. Part of the 28M series, they are mounted using Through-Hole Technology (THT) and are suitable for Commercial Off-The-Shelf (COTS) applications. With an inductance of 2.7 µH and a minimum Q factor of 60, they operate at a test frequency of 7.9 MHz. The coils have a DC resistance of 0.22 ohms and a self-resonant frequency of 115 MHz, with a current rating of 1.35 A DC. They feature a dielectric withstanding voltage of 1000, 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 +105°C, have a moisture sensitivity level of 1, and are packaged in tape and reel format. Additionally, they are fungal inert, ensuring durability and reliability in various environments.
