The 3252W-1-503 is a 1/2" square Trippet® multiturn trimming potentiometer manufactured by Bourns with cermet element and sealed construction. This device features a resistance range of 10 to 2 megohms with ±10% standard tolerance, infinite resolution, and 25 turns of effective travel for precise voltage and resistance adjustability (±0.01% voltage, ±0.05% resistance). It operates across a wide temperature range of -65°C to +150°C with a temperature coefficient of ±100 PPM/°C, and is rated for 0.75 watt at 85°C with a maximum voltage of 400 volts. The potentiometer is listed on the QPL for style RJ22 per MIL-R-22097, features solderable printed circuit pins with flexible leads, and is available in RoHS compliant versions, making it suitable for precision trimming applications in instrumentation, signal processing, and industrial control systems.
