Gowanda’s 19F503M is a high-quality molded unshielded RF coil designed for reliable performance in various applications. Weighing 1.3 grams, this component features dimensions of 11.176 × 4.826 × 4.826 mm and belongs to the 19F series. It is a through-hole technology (THT) component with a commercial off-the-shelf (COTS) application grade, offering an inductance of 500 µH and a direct current resistance (DCR) of 8.6 ohms. The coil has a self-resonant frequency (SRF) of 3.7 MHz and a current rating of 0.18 A DC, with a dielectric withstanding voltage (DWV) of 200. It has a tolerance of ±20% and uses a lead-based termination type with a Sn63Pb37 finish. The core is made of ferrite, and the component is not shielded. It operates effectively within a temperature range of -55°C to +125°C and is packaged in tape and reel (T&R) format. The 19F503M is not fungal inert.
