Flexible Lead NTC Thermistors

Flexible Thermistors are NTC thermistors which have flexible insulation to help simplify product assembly or provide unique monitoring solutions. Using flexible thermistors will help to speed up assembly and thus minimise production handling costs.  Their small bead size give faster, accurate sensing and/or temperature control in numerous domestic and commercial applications.

Our range options include:

  • Semitec JT range ultra-thin flexible film NTC thermistors
  • Semitec ET series NTCs with thin lead-wires enabling very fast response times
  • Semitec AT-4 thermistors with flexible PVC insulated wire for simplified assembly
  • Semitec 103AT-11 thermistor sensors offer IP67 integrity and industry standard temperature control

These basic thermistors can also be customised to meet exacting requirements and supplied with connectors or various housings.  Widely used in commercial refrigeration, e-vehicle batteries and home automation products, Semitec flexible thermistors provide the ultimate temperature sensor /probe solution.

If higher levels of accuracy are required, please review our range listed within Precision NTC  Thermistors.
