Gowanda’s 50PX4703H is a radial-leaded horizontal mount toroidal choke designed for high reliability and performance in electronic applications. This component, part of the PX series, features a compact design with dimensions of 15.75 × 15.75 × 8.64 mm and a weight of 5.75 g. It is suitable for through-hole technology (THT) mounting and is classified under the COTS+ application grade, ensuring it meets commercial off-the-shelf standards with enhanced reliability. The choke offers an inductance of 470 µH, a direct current resistance (DCR) of 0.4 Ω, and a self-resonant frequency (SRF) of 1 MHz. It supports a current rating of 1.1 A DC, with incremental current limits of 300 mA DC for a 10% inductance change and 500 mA DC for a 20% change. The component has a tolerance of ±15% and features lead (Pb) termination with a Sn63Pb37 finish. It operates efficiently across a wide temperature range from -55°C to +130°C, has a moisture sensitivity level (MSL) of 1, and is available in bulk packaging.
