Gowanda’s 19M433M 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. They belong to the 19M series and are mounted using Through-Hole Technology (THT). With an inductance of 430 µH and a minimum Q factor of 65, these coils are suitable for COTS application grades. They operate at a test frequency of 0.79 MHz, with a DC resistance of 10.6 ohms and a self-resonant frequency of 4.3 MHz. The current rating is 0.097 A DC, and they can withstand a dielectric withstanding voltage (DWV) of 180. The coils have a tolerance of ±20% and feature Pb termination with a Sn63Pb37 finish. Constructed with a powdered iron core, they are not shielded but are fungal inert, ensuring durability in various environments. They operate within a temperature range of -55°C to +105°C, have a moisture sensitivity level (MSL) of 1, and are packaged in tape and reel (T&R) format.
