T200 Series NTC Thermistors, Insulated Leads
The T200 Series NTC thermistors with insulated leads are ready for use as is or for encapsulation in either plastic or metal housings for added protection. Insulated leads eliminate the costly task of individually insulating the leads with insulation tubing prior to encapsulation in a probe housing. The T200 Series is not only available in the standard two leaded, single thermistor construction; it is also available in the 6k/30k three leaded, dual thermistor composite. The T200 Series thermistor construction is noted for its ruggedness, reliability, and stability. Custom products are available.

•Twenty-three basic styles
•Insulated leads
•Radial, twisted pair, parallel bonded, twisted triplet [6k/30k composite] lead configurations
•Typical overall lead lengths 3 in [76.2 mm] to 36 in [914.4 mm]
•Epoxy coating and phenolic coatings
•Standard R25 values from 2252 Ω to 100,000 Ω
•Available in point matched and interchangeable tolerances
•Custom and semi-custom products may be specified
•Ideal for use in temperature probes
