Gowanda’s 50PX4703V is a radial-leaded vertical mount toroidal choke, part of the PX series, designed for high-quality, reliable electronic applications. This component weighs 5.7 grams and measures 15.75 × 15.75 × 8.64 mm, with a through-hole technology (THT) mounting type. It is suitable for COTS+ application grades, offering an inductance of 470 µH and a direct current resistance (DCR) of 0.4 Ω. The self-resonant frequency (SRF) is 1 MHz, with a current rating of 1.1 A DC. The choke can handle incremental current levels of 300 mA DC at a 10% inductance change and 500 mA DC at a 20% change, with a tolerance of ±15%. It features a lead (Pb) termination type with a Sn63Pb37 finish, and operates within a temperature range of -55°C to +130°C. The moisture sensitivity level (MSL) is rated at 1, and it is available in bulk packaging.
