Rigid Lead Wire NTCs

We have an array of thermistors suitable for medical temperature sensing, with our F-Micro Miniature Thermistor having a multitude of applications due to its small size and precise design. These allow it to be easily supplied in tubes as small as 0.28mm, and combined with a high thermal accuracy of 0.14K at 37°C make it our most advanced thermistor available.                                                                                                           

For non-contact applications, the NC temperature sensor utilises the latest FT thermistor technology to sense infrared energy with a high signal strength.

There is no easy formula in deciding which is the best NTC thermistor for your application as there are many different factors to take into consideration.

Factors to take into consideration include levels of accuracy, resistance values, shapes and size.

At ATC Semitec we have more than 25 years of experience in providing thermal solutions for industry. Give us a call today for expert technical advice, and to request samples.

NTC thermistors can be supplied in different configurations/housings depending on your applications:

Epoxy coated generally for lower temperature use (-60°C to +150°C)

Glass encapsulated ideal for use in high temperature applications ( -50°C to +300°C)

Within temperature probe assemblies – with IP67 or IP68 ratings if required.

SMD (surface mount) packages down to 0201 size

Threaded or boss mounted, metal encapsulated temperature sensors.

NTC thermistors are used in a large number of temperature sensors in everyday life and include :-

• Home appliances (Temperature control of ovens and fridges)
• Personal care (Hair-dryers, stylers)
• Medical devices (Catheters, thermometers, glucose monitors)
• Smart devices/IOT products (Home automation, domotics)
• Battery monitoring (Overcharge, over-discharge)
• Automotive/E-Vehicles (Cabin temp, battery monitoring, EGR)
• HVAC appliances (Air temperature, condenser temps)
• Fire & security (Heat detectors, smoke detectors)
• Office automation (Copier & laser printer fuser rollers)

Some larger disc NTC thermistors (or power thermistors) are used for current inrush limiting.  They offer a neat, cost-effective solution to surge currents arising from switching on some electronic or electrical products, e.g. Switch Mode Power Supplies, LED drivers and halogen lamps or heaters.

NTC thermistors have a high temperature coefficient of resistance (TCR), are very stable and have excellent repeatability.

Readily available in numerous form factors, they are also;

• Highly accurate (± 1% tolerance or better)
• Thermally very fast (Tc ~1s)
• Very compact (SMD, thin-film and tiny beads)
• Low-cost (highly competitive)
• Interchangeable – No re-calibration required
• Point matching – Can be calibrated at a specific working temperature
• Wide temperature operating range (-60°C/+300°C).

They are also highly customisable to suit your application.

NTC Thermistors (Negative Temperature Coefficient) are basically thermal resistors whose resistance drops when the temperature increases.  When the term thermistor is used, engineers often mean NTC thermistors.

An NTC thermistor has a high resistance at low temperature, and as the temperature increases the resistance decreases rapidly. Therefore NTCs offer the benefit of highly accurate and quick response times to very small changes in temperature.

These are generally used for temperature measurement as their RT (Resistance – Temperature) characteristic is very well defined and can be readily programmed.

Thermistors are manufactured from metal oxide semiconductor materials encapsulated in impermeable materials such as epoxy or glass. These coatings protect the thermistor bead and lead-wire connections mechanically whilst also providing protection against humidity.

Thermistors are very simple to incorporate electronically (and physically) as they exhibit a large change in resistance/°C when compared with other sensor types.

So they are very robust, available in numerous form factors and can be readily used from -60°C to +300°C.

Typical applications for thermistors include: 

• Temperature Measurement
• Temperature Control
• Temperature Compensation
• Inrush Current Limiting
• Over-Temperature Solid-State Switches

Thermistors are thermally sensitive resistors, which show a precise and predictable resistance change in direct proportion to their change in temperature.

There are 2 main types of Thermistor:

NTC Thermistors (Negative Temperature Coefficient) whose resistance drops as the temperature increases.

PTC Thermistors (Positive Temperature Coefficient) whose resistance increases rapidly as the temperature increases.

The differences are readily explained in the below diagram;
