描述

The RT26C2X202 is a 1/4" square Trimpot® trimming potentiometer designed for precision adjustment in industrial sealed applications and listed on the QPL per MIL-PRF-27208. This multiturn wirewound device features a 2,000 ohm resistance with ±5% tolerance, 11 turns nominal adjustment angle, and a nominal resolution of 0.45%. It operates over a temperature range of -55°C to +150°C with a temperature coefficient of ±50 ppm/°C, and delivers 0.25 watts at 85°C. The potentiometer exhibits excellent environmental durability with 1,000 megohms minimum insulation resistance at 500 VDC, withstands 20 G vibration and 100 G shock, and maintains performance through 200 rotational cycles and 1,000 hours of load life testing. Its sealed construction, low torque requirement (3.0 oz-in. max.), and MIL-spec compliance make it ideal for aerospace, military, and high-reliability instrumentation applications requiring precise, stable resistance adjustment.
