62 features: ? rugged, low cost, very high reliability ? operation from -50?c up to 300?c ? values from 2186 to 1.38m at 25?c ? standard tolerance of 3% at rated temp ? temperature measurement and control ? fast response time ? high temperature stability ? glass encapsulation provides resistance to moisture and other environmental factors ? available in ceramic reinforced glass body or glass bead confgurations description: ms radial leaded glass encapsulated thermistors provide a low cost option for applications that require superior stability and high temperature operation. the therm - istors are glass encapsulated to allow for operation in a wide array of environments including high humidity and rapid thermal cycling. the small size allows the sensor to react quickly to small temperature changes. contact the factory for specifc design or application information or the availability of options. ceramic reinforced glass bead thermistor glass bead thermistor standard resistance tolerance is 3% at rated temperature *see r/t tables on page 63. basic p/n material tol. code point-match temperature (c) (only used if other than 25c) ms part number resistance @25?c (ohms) resistance specifcation (3%) ms matl 25/85 (kelvin) GC2183T-3-0 2186 6,000 @ 0?c t 3420 2% gc5373u-3-0 5369 15,000 @ 0?c u 3480 2% gc1074u-3-0 10,739 30,000 @ 0?c u 3480 2% gc4914a-3-100 49,120 3,300 @ 100?c a 3992 2% gc9864n-3-200 98,633 550 @ 200?c n 4066 3% gc2315r-3-200 231,440 1,000 @ 200?c r 4240 3% gc1396v-3-200 1,388,100 4,000 @ 200?c v 4557 3% dissipation factor ( ) is 1.5mw/?c time constant ( ) is 18 sec nominally max operating temperature is 300?c ms part number resistance @25?c (ohms) resistance specifcation (3%) ms matl 25/85 (kelvin) gb2183t-3-0 2186 6,000 @ 0?c t 3420 2% gb5373u-3-0 5369 15,000 @ 0?c u 3480 2% gb1074u-3-0 10,739 30,000 @ 0?c u 3480 2% gb4914a-3-100 49,120 3,300 @ 100?c a 3992 2% gb9864n-3-200 98,633 550 @ 200?c n 4066 3% gb2315r-3-200 231,440 1,000 @ 200?c r 4240 3% gb1396v-3-200 1,388,100 4,000 @ 200?c v 4557 3% dissipation factor ( ) is 0.75mw/?c time constant ( ) is 6 sec nominally max operating temperature is 300?c examples: gc1074u-3-0 .............. curve u material, 3% at 0?c gb1396v-3-200 ........... curve v material, 3% at 200?c radial leaded glass encapsulated style temperature sensor products 1028 graphite road, st. marys, pa 15857 8-7-13 precisionsensors.meas-spec.com ph: 814.834.1541 fax: 814.834.1556 www.meas-spec.com
