Gowanda’s 18M470M Molded Unshielded RF Coils are high-quality electronic components designed for reliable performance in various applications. Weighing 0.95 grams and measuring 11.125 × 4.775 × 4.775 mm, these coils are part of the 18M series and feature a through-hole technology (THT) mounting type. They are suitable for commercial off-the-shelf (COTS) applications, offering an inductance of 0.47 µH with a minimum Q factor of 50 at a test frequency of 25 MHz. The coils have a direct current resistance (DCR) of 0.085 Ω, a self-resonant frequency (SRF) of 300 MHz, and a current rating of 1.7 A DC. With a dielectric withstanding voltage (DWV) of 200, they maintain a tolerance of ±20%. The termination type is lead-based with a Sn63Pb37 finish, and the core material is phenolic. 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) format, they are also fungal inert, ensuring durability and reliability in demanding environments.
