The 3299Y-1-102LF is a 3/8" square multiturn cermet trimming potentiometer (Trimpot) designed for industrial sealed applications. This model features a nominal resistance of 1,000 ohms (102 code), with ±10% standard tolerance and infinite resolution across 25 turns of effective travel. The device 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 Y-style terminal configuration includes 100% tin-plated (RoHS compliant) solderable pins, and the unit meets UL 94V-0 flammability standards with sealed construction for reliability in harsh environments. Common applications include precision circuit tuning, signal conditioning, and calibration adjustments in industrial control systems and instrumentation.
