Gowanda’s 10M431M Molded Unshielded RF Coils are high-quality electronic components designed for reliable performance in various applications. With a weight of 0.3 grams and dimensions of 6.35 × 2.413 × 2.413 mm, these coils are part of the 10M series and feature a through-hole mounting type (THT). They are suitable for commercial off-the-shelf (COTS) applications, offering an inductance of 4.3 µH and a minimum Q factor of 45 at a test frequency of 7.9 MHz. The coils have a DC resistance of 1.1 ohms, a self-resonant frequency of 77 MHz, and a current rating of 240 mA DC. With a dielectric withstanding voltage (DWV) of 300, they maintain a tolerance of ±20%. The termination type is lead-based with a Sn63Pb37 finish, and the core is made of powdered iron. These components are not shielded and operate within a temperature range of -55°C to +105°C, with 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.
