The 67XR1KLF is a Model 67 cermet trimming potentiometer designed for applications requiring adjustability and calibration. It features a 3/8" square multiturn design with 20 turns nominal electrical travel and is sealed with 85°C Fluorinert to ensure compatibility with aqueous PCB cleaning processes. The potentiometer supports a standard resistance range from 10 Ohms to 2 Megohms with ±10% tolerance (±20% for values below 100 Ohms), operates at up to 200 Vdc maximum input voltage, and delivers 0.5 Watts power rating at 85°C. With an operating temperature range of -55°C to +125°C, dielectric strength of 900 Vrms, and insulation resistance of 1,000 Megohms minimum, this component provides highly reliable performance for medical, consumer electronics, and industrial calibration applications.
