Gowanda’s 19M303M Molded Unshielded RF Coils are high-quality electronic components designed for reliable performance in various applications. These coils weigh 1.3 grams and have dimensions of 11.176 × 4.826 × 4.826 mm. Part of the 19M series, they feature a Through-Hole Technology (THT) mounting type and are suitable for Commercial Off-The-Shelf (COTS) applications. With an inductance of 300 µH and a minimum Q factor of 65, they operate at a test frequency of 0.79 MHz. The coils have a DC resistance of 8.7 ohms, a self-resonant frequency of 5.3 MHz, and a current rating of 0.107 A DC. They are designed with a dielectric withstanding voltage (DWV) of 180 and 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, have an operating temperature range from -55°C to +105°C, and are rated at moisture sensitivity level (MSL) 1. They are packaged in tape and reel (T&R) and are fungal inert.
