Gowanda’s 15M331M Molded Unshielded RF Coils are high-quality electronic components designed for reliable performance in various applications. These coils weigh 0.65 grams and have dimensions of 9.525 × 3.962 × 3.962 mm. They belong to the 15M series and are mounted using Through-Hole Technology (THT). With an inductance of 3.3 µH and a minimum Q factor of 33, these coils operate at a test frequency of 7.9 MHz. They feature a DC resistance of 2 ohms and a self-resonant frequency of 110 MHz, with a current rating of 0.3 A DC. The dielectric withstanding voltage is 1000, and they have 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 but are fungal inert and can operate in temperatures ranging from -55°C to +125°C. They have a moisture sensitivity level of 1 and are available in tape and reel packaging.
