Gowanda’s 18M222M Molded Unshielded RF Coils are designed for high reliability and performance in electronic applications. Weighing 0.95 grams and measuring 11.125 × 4.775 × 4.775 mm, these coils are part of the 18M series and are mounted using Through-Hole Technology (THT). They are suitable for Commercial Off-The-Shelf (COTS) applications, offering an inductance of 22 µH with a minimum Q factor of 60 at a test frequency of 2.5 MHz. The coils have a DC resistance of 2.2 ohms and a self-resonant frequency of 24 MHz, with a current rating of 0.24 A DC. They are designed to withstand a dielectric withstanding voltage of 200 volts and have 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 effectively within a temperature range of -55°C to +125°C. They have a moisture sensitivity level of 1 and are packaged in tape and reel format. Additionally, they are fungal inert, ensuring durability in various environments.
