Gowanda’s 15M391M Molded Unshielded RF Coils are high-quality electronic components designed for reliable performance in various applications. These coils weigh 0.65 grams and have dimensions of 9.525 × 3.962 × 3.962 mm. Part of the 15M series, they feature a through-hole mounting type (THT) and are suitable for commercial off-the-shelf (COTS) applications. With an inductance of 3.9 µH and a minimum Q factor of 33, they operate at a test frequency of 7.9 MHz. The coils have a DC resistance of 2.3 ohms, a self-resonant frequency of 100 MHz, and a current rating of 0.28 A DC. They can withstand a dielectric withstanding voltage (DWV) of 1000 volts and have a tolerance of ±20%. The termination type is lead-based (Pb) with a Sn63Pb37 finish, and the core is made of phenolic material. These components are not shielded, have an operating temperature range from -55°C to +125°C, and are rated 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 various environments.
