Gowanda’s 21M560M Molded Unshielded RF Coils are high-quality electronic components designed for reliability and performance. Weighing 1.7 grams and measuring 14.224 × 5.588 × 5.588 mm, these coils are part of the 21M series and feature a Through-Hole Technology (THT) mounting type. They are suitable for Commercial Off-The-Shelf (COTS) applications, offering an inductance of 0.56 µH with a minimum Q factor of 65 at a test frequency of 25 MHz. The coils have a DC resistance of 0.08 ohms and a self-resonant frequency of 270 MHz, with a current rating of 1.85 A DC. They are designed to withstand dielectric withstanding voltages of 1000 and 200, with 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.
