The 3299Z-1-102LF is a 3/8" square multiturn cermet trimming potentiometer (Trimpot) designed for industrial sealed applications requiring precision resistance adjustment. This model features a 1 kO nominal resistance value with ±10% tolerance, infinite resolution, and 25 turns of effective travel for fine-tuning control. It operates across 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 device is RoHS compliant with 100% tin-plated (LF) terminations, offers excellent dielectric strength of 1,000 MO minimum, and includes mechanical stops with a wiper set at 50% of actual travel resistance. Common applications include circuit calibration, signal conditioning, and precision tuning in industrial control systems and instrumentation where reliable, sealed operation is essential.
