Gowanda’s 28M152M series offers high-quality molded unshielded RF coils designed for reliable performance in various applications. These components weigh 2.65 grams and have dimensions of 22.86 × 7.137 × 7.137 mm, making them suitable for through-hole technology (THT) mounting. With an inductance of 15 µH and a minimum Q factor of 40, they operate efficiently at a test frequency of 2.5 MHz. The coils feature a DC resistance of 3.25 Ω and a self-resonant frequency of 50 MHz, supporting a current rating of 0.355 A DC. They are constructed with a phenolic core and have a dielectric withstanding voltage (DWV) of 1000, 200. The components are rated for operation in temperatures ranging from -55°C to +105°C and are packaged in tape and reel (T&R) format. With a tolerance of ±20% and a termination finish of Sn63Pb37, these coils are classified as commercial off-the-shelf (COTS) and are fungal inert, ensuring durability and reliability in demanding environments.
