68WR1M General Description

The 68WR1M is designed as one kind of 3/8" square multiturn cermet trimming potentiometer.The electrical characteristics of it can be summarized as:(1)standard resistance range,Ohms:10 to 2Meg;(2)standard resistance tolerance:±10% (<100 Ohms=±20%);(3)input voltage,maximum:200 Vdc or rms not to exceed power rating;(4)slider current,maximum:100mA or within rated power, whichever is less;(5)power rating, watts:0.5 at 85°C derating to 0 at 125°C;(6)end resistance,maximum:2 Ohms;(7)actual electrical travel,turns,nominal:20;(8)dielectric strength:900 Vrms;(9)insulation resistance,minimum:1,000 megohms;(10)resolution:essentially infinite;(11)contact resistance variation,maximum:1% or 1 Ohm, whichever is greater.

The environmental of the 68WR1M are:(1)temperature coefficient,maximum:±100ppm/°C;(2)seal:85°C fluorinert® (no leaks);(3)temperature range:-55°C to +125°C;(4)thermal shock:5 cycles,-55°C to +125°C (1% RT,1% VR);(5)moisture resistance:ten 24 hour cycles (1% RT,IR 1,000 Megohms min.);(6)shock, 6ms sawtooth:100G's (1% RT, 1% VR);(7)vibration:20G's, 10 to 2,000 Hz (1% RT, 1% VR);(8)high temperature exposure:250 hours at 125°C (2% RT, 2% VR);(9)rotational life:200 cycles (3% RT);(10)load life at 0.5 watts:1,000 hours at 70°C (2% RT);(11)resistance to solder heat:260°C for 10 sec. (1% RT).

And three points of mechanical characteristics of 68WR1M are:(1)mechanical stops:clutch action, both ends;(2)torque, starting maximum:5 oz.-in. (0.035 N-m);(3)weight, nominal.If you want to know more information such as the electrical characteristics about the 68WR1M,please download the datasheet in www.seekic.com or www.chinaicmart.com .
