Good Stability Quick Response 22D15 NTC Thermal Resistor Small Residual Resistance
Principle:
The principle of measuring temperature with a thermistor is that its resistance changes with temperature. Most thermistors differ from ordinary resistors in that they have a negative resistivity, meaning that resistance decreases as temperature increases. Negative (NTC) thermistors are more common, although positive (PTC) thermistors can be used.
Material, type and size:
Thermistors are bulk semiconductor devices and as such can be manufactured in a variety of forms. More common ones include discs, beads and rods. Sizes do vary from 1mm beads to discs a few centimeters in diameter and thickness.
There are different types of thermistors, most of which respond differently to changes in temperature. Thermistors are not linear and their response curves vary from type to type. Some thermistors have a nearly linear temperature-resistance relationship, others have a sharp change in slope (sensitivity) at a specific characteristic temperature.
The main advantage
The main feature of a thermistor is its high sensitivity. Its temperature coefficient of resistance is 10-100 times that of metal. It can detect temperature changes of 10-6°C; the working temperature range is wide, the normal temperature device is suitable for -55°C ~ 315°C, the high temperature device is suitable for temperatures above 315°C (before 2000°C), and the low temperature device is suitable for- 273°C ~ 55°C; small size, can measure the temperature of the voids, cavities and blood vessels in the human body, which cannot be measured by other thermometers; easy to use, the resistance value is in the range of 0.1 ~ 100kΩ; any choice between them; easy to process into Complex shape, mass production; good stability, strong overload capacity.
Applications:
Can be installed into the power circuits of:
• Power supplies and inverters
• Uninterruptible Power Supplies
• Energy saving lamps
• Electronic Ballasts
• Filament Protection of various types of lamps
• Some types of heaters
• For higher power circuits ask about the MF73
and MF74 series surge suppressors.
