Gowanda’s 28M182M Molded Unshielded RF Coils are high-quality electronic components designed for reliable performance in various applications. These coils feature a weight of 2.65 grams and dimensions of 22.86 × 7.137 × 7.137 mm, making them suitable for through-hole technology (THT) mounting. With an inductance of 18 µH and a minimum Q factor of 40, they operate at a test frequency of 2.5 MHz. The coils have a direct current resistance (DCR) of 4.15 ohms and a self-resonant frequency (SRF) of 45 MHz, supporting a current rating of 0.315 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 with a Sn63Pb37 finish, and the core is made of phenolic material. These coils are not shielded, operate within a temperature range of -55°C to +105°C, and have a moisture sensitivity level (MSL) of 1. Packaged in tape and reel (T&R) format, they are also fungal inert, ensuring durability and reliability in commercial off-the-shelf (COTS) applications.
