Beckman Industrial 72XWR20K is a through-hole trimmer potentiometer with a nominal resistance of 20 kΩ and a ±10% tolerance, intended for fine, repeatable calibration on printed circuit boards. This cermet trimmer uses a three-terminal through-hole package and is adjusted with a small screwdriver to trim reference voltages, offsets, and signal-path resistances in instrumentation, control electronics, and power-supply circuitry. Distributors commonly offer the 72XWR20K in packs, such as 100 pieces per pack, making it a standard choice for routine calibration tasks that require a reliable 20 kΩ adjustment.
