Gowanda’s 21M122M Molded Unshielded RF Coils are a part of the Series 21M, designed for high-quality, reliable electronic applications. These coils weigh 1.7 grams and have dimensions of 14.224 × 5.588 × 5.588 mm, with a Through-Hole Technology (THT) mounting type. They are suitable for Commercial Off-The-Shelf (COTS) applications, offering an inductance of 12 µH and a minimum Q factor of 45 at a test frequency of 2.5 MHz. The coils have a DC resistance of 0.45 ohms and a self-resonant frequency of 34 MHz, with a current rating of 0.465 A DC. They feature a dielectric withstanding voltage (DWV) of 1000, 200 and a tolerance of ±20%. The termination type is lead-based with a Sn63Pb37 finish, and the core is made of powdered iron. These coils are not shielded and operate within a temperature range of -55°C to +105°C, with a moisture sensitivity level (MSL) of 1. They are packaged in tape and reel (T&R) and are fungal inert.
