The 3299X-1-504LF is a 3/8" square multiturn cermet trimming potentiometer (Trimpot) designed for industrial applications requiring precision adjustment and sealed operation. This model features a resistance value of 500 kO (code 504), with ±10% standard tolerance and infinite resolution across 25 turns of effective travel. The potentiometer operates over a temperature range of -55°C to +125°C with a temperature coefficient of ±100 ppm/°C, and is rated for 0.5 watts at 70°C with a maximum voltage of 300 volts. The X-style terminal configuration provides solderable pins with 100% tin-plated (RoHS compliant) termination, and the device meets UL 94V-0 flammability standards. This sealed, multiturn design is ideal for precision tuning applications in industrial equipment, instrumentation, and control systems where reliable, repeatable adjustment is essential.
