Radial Leaded Glass Encapsulated Style Features: • • • • • • • • • Description: MS radial leaded glass encapsulated thermistors provide a low cost option for applications that require superior stability and high temperature operation. The thermistors 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 specific design or application information or the availability of options. Rugged, low cost, very high reliability Operation from -50˚C up to 300˚C Values from 2186Ω to 1.38MΩ 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 configurations CERAMIC REINFORCED GLASS BEAD THERMISTOR MS Part Number Resistance @25˚C (Ohms) Resistance Specification (±3%) GLASS BEAD THERMISTOR MS Matl (Kelvin) MS Part Number b25/85 Resistance @25˚C (Ohms) Resistance Specification (±3%) MS Matl (Kelvin) b25/85 GC2183T-3-0 2186 6,000Ω @ 0˚C T 3420 ± 2% GB2183T-3-0 2186 6,000Ω @ 0˚C T 3420 ± 2% GC5373U-3-0 5369 15,000Ω @ 0˚C U 3480 ± 2% GB5373U-3-0 5369 15,000Ω @ 0˚C U 3480 ± 2% GC1074U-3-0 10,739 30,000Ω @ 0˚C U 3480 ± 2% GB1074U-3-0 10,739 30,000Ω @ 0˚C U 3480 ± 2% GC4914A-3-100 49,120 3,300Ω @ 100˚C A 3992 ± 2% GB4914A-3-100 49,120 3,300Ω @ 100˚C A 3992 ± 2% GC9864N-3-200 98,633 550Ω @ 200˚C N 4066 ± 3% GB9864N-3-200 98,633 550Ω @ 200˚C N 4066 ± 3% GC2315R-3-200 231,440 1,000Ω @ 200˚C R 4240 ± 3% GB2315R-3-200 231,440 1,000Ω @ 200˚C R 4240 ± 3% GC1396V-3-200 1,388,100 4,000Ω @ 200˚C V 4557 ± 3% GB1396V-3-200 1,388,100 4,000Ω @ 200˚C V 4557 ± 3% Dissipation factor (d) is 1.5mW/˚C Time constant (t) is 18 sec nominally Max operating temperature is 300˚C Dissipation factor (d) is 0.75mW/˚C Time constant (t) is 6 sec nominally Max operating temperature is 300˚C Standard resistance tolerance is ±3% at rated temperature Basic P/N Examples: Material Tol.

MS uses the Steinhart-Hart equation to calculate the nominal Rt/ R25 value. 1°C tables are available upon request. Temperature Sensor Products precisionsensors.meas-spec.com • α25 - Negative Temperature Coefficient of Resistance at 25˚C expressed in %/˚C. This is the percentage change in thermistor resistance for a 1°C change in its' body temperature at 25˚C. α is particularly useful in calculating the required resistance tolerance necessary to guarantee sensor accuracy. α at temperatures other than 25˚C is available upon request as tables in 1˚C increments. 1711 139th Lane NW Andover, MN 55304 Ph: +1 800.899.9783 12-04-14 63 www.meas-spec.com NTC Thermistors MS Type
