Gowanda’s 21M151M Molded Unshielded RF Coils are designed for high-quality, reliable performance in electronic applications. These coils weigh 1.7 grams and have dimensions of 14.224 × 5.588 × 5.588 mm. Part of the 21M series, they feature through-hole technology (THT) mounting and are suitable for commercial off-the-shelf (COTS) applications. With an inductance of 1.5 µH and a minimum Q factor of 40, they operate at a test frequency of 7.9 MHz. The coils have a DC resistance of 0.28 ohms and a self-resonant frequency of 160 MHz, supporting a current rating of 0.925 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 +125°C, and have a moisture sensitivity level (MSL) of 1. Packaged in tape and reel (T&R), they are also fungal inert, ensuring durability and reliability in various environments.
