Gowanda’s 28M122M 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, making them suitable for through-hole technology (THT) mounting. Part of the 28M series, they are classified as Commercial Off-The-Shelf (COTS) grade, with an inductance of 12 µH and a minimum Q factor of 40 at a test frequency of 2.5 MHz. The coils feature a DC resistance of 2.65 Ω, a self-resonant frequency of 53 MHz, and a current rating of 0.395 A DC. They are designed to withstand dielectric withstanding voltages (DWV) of 1000 and 200, with a tolerance of ±20%. The termination type is lead-based (Pb) 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 +105°C. They have a moisture sensitivity level (MSL) of 1 and are available in tape and reel (T&R) packaging.
