Flexible 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 size give fast, 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 solution.

 

Call us today on 01606 871680 to discuss your application’s thermal sensor requirements.  Using our extensive technical knowledge and innovative supplier base, we will work with you to provide the optimum solution for your product.

 

 

  • Semitec AT-2 High Accuracy NTC Thermistor

    The Semitec AT-2 range of NTC thermistors were the first to use lead-frame technology to create consistently accurate 1% tolerance NTC’s at a significant lower-cost than other NTC products. Their unified shape enables automatic assembly.

    • Lead frame technology
    • Consistent accuracy. 1% tolerance
    • Unified shape for automatic assembly.
    • Seven R25 range values
    • Stock Available ; 102AT-2, 202AT-2, 502AT-2, 103AT-2, 203AT-2,503AT-2, 104AT-2
  • Semitec AT-4 HIgh Accuracy Lead Wire NTC Thermistors

    Semitec AT-4 thermistors have flexible, PVC insulated lead-wires and so they offer all the technical benefits of the AT-2 ntc thermistor and also help to simplify the battery assembly process.
    There are two main wire gauges available (30AWG or 26AWG) with the following 10kohm versions readily available from stock;
    103AT-4-70374 (50mm 30AWG PVC leads)
    103AT-4-70261 (100mm 30AWG PVC leads)
    103AT-4-10228 (150mm 30AWG PVC leads)
    103AT-4-61046 (175mm 26AWG PVC leads)
    Call us to discuss any specific requirements.

  • Semitec AT-5 Lead In NTC Thermistor

    Semitec 103AT-5 thermistors incorporate the same NTC element as the 103AT-2 but are fitted with 30mm long solid bare lead-wires (0.5mm dia) and can be supplied in bulk form or tape & reel or ammo-pack.

    Call us to discuss any auto-insertion requirements you have for NTC thermistors.

  • ATC Semitec ATC3 Radial High Accuracy NTC Thermistor
    • High accuracy 1% tolerances
    • High accuracy over wide temperatures -40°C/+125°C
    • Epoxy coated lead formed thermistor
  • Semitec 103 AT-11 IP67 Temperature Sensors

    Semitec AT-11 thermistor sensors are TPE encapsulated sensors suitable for temperatures from -50°C/+110°C, and offers excellent and accurate low-cost solution for general temperature sensing applications.

    • Fast response to thermal change – sensing portion 5mm x 6mm x 15mm,
    • Sensor tip is sealed to the lead wires during the moulding process to ensure IP67 integrity – can be used where moisture ingress is normally a problem,
    • Insulation strength to 3.75kV.
    • Uses our highly reliable 103AT-2 thermistor (accuracy ±0.3°C at 25°C)
    • Other R25/B value combinations using our AT-2 and AP-2 series thermistors are also available for volume applications.

     

    Available from stock is the standard 600mm long 103AT-11, as well as 1.5m and 3m long versions.

  • Semitec JT Ultra-Thin Film NTC Thermistor

    Semitec’s JT series of thermistors are ultra-thin flexible film NTCs that give a very fast response to temperature change. Whilst increasingly used within medical device application, it is a versatile thermistor which is used within battery packs, mobile devices and surface/air  temperature sensors.
