Gowanda’s 21M392M Molded Unshielded RF Coils are high-quality electronic components designed for reliable performance in various applications. These coils weigh 1.7 grams and have dimensions of 14.224 × 5.588 × 5.588 mm, making them compact yet efficient. They belong to the 21M series and are mounted using Through-Hole Technology (THT). With an inductance of 39 µH and a minimum Q factor of 70, these coils are suitable for COTS-grade applications. They operate at a test frequency of 2.5 MHz, with a DC resistance of 2 ohms and a self-resonant frequency of 18 MHz. The current rating is 0.224 A DC, and they can withstand a dielectric withstanding voltage of 1000, 200. The coils have a tolerance of ±20% and feature a Pb termination type 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 of 1, and are available in tape and reel packaging.
