Gowanda’s 19M623M Molded Unshielded RF Coils are high-quality electronic components designed for reliable performance in various applications. With a weight of 1.3 grams and dimensions of 11.176 × 4.826 × 4.826 mm, these coils are part of the 19M series and feature through-hole technology (THT) mounting. They are classified as Commercial Off-The-Shelf (COTS) grade, offering an inductance of 620 µH and a minimum Q factor of 60. Tested at a frequency of 0.79 MHz, they have a DC resistance of 13 ohms and a self-resonant frequency of 3.5 MHz. The current rating is 0.088 A DC, with a dielectric withstanding voltage (DWV) of 180. These coils have a tolerance of ±20% and use leaded (Pb) termination with a Sn63Pb37 finish. Constructed with a powdered iron core, they are not shielded and operate within a temperature range of -55°C to +105°C. They have a moisture sensitivity level (MSL) of 1 and are packaged in tape and reel (T&R) format, ensuring they are fungal inert.
