Gowanda’s 19M333M is a high-quality molded unshielded RF coil designed for reliable performance in various electronic applications. Weighing 1.3 grams and measuring 11.176 × 4.826 × 4.826 mm, this component is part of the 19M series and is mounted using through-hole technology (THT). It is suitable for commercial off-the-shelf (COTS) applications, offering an inductance of 330 µH with a minimum Q factor of 65 at a test frequency of 0.79 MHz. The coil features a direct current resistance (DCR) of 9.1 Ω and a self-resonant frequency (SRF) of 5 MHz, with a current rating of 0.105 A DC. It is constructed with a powdered iron core and has a dielectric withstanding voltage (DWV) of 180. The component is lead-terminated with a Sn63Pb37 finish and operates effectively within a temperature range of -55°C to +105°C. It is packaged in tape and reel (T&R) format, is moisture sensitivity level (MSL) 1, and is fungal inert, ensuring durability and reliability in demanding environments.
