Temperature Sensors - PTC Thermistors

PTC thermistors (positive temperature coefficient thermistors), also referred to as self-regulating heaters, are thermally activated semiconductor devices designed to automatically maintain and control a specific temperature in a given application. The most common type of PTC thermistor is the P5010D135S401H, these devices provide reliable temperature protection and control while offering adjustment free performance and high accuracy in a wide range of applications.

P5010D135S401H Application Field

The P5010D135S401H is a surface mount thermistor chip that is used in a variety of applications, but works best in industrial temperature control and monitoring applications. The temperature range this device is effective for is from -40°C to +150°C, which makes it suitable for many areas, such as consumer electronics, domestic appliances, and high-end industrial processes. The P5010D135S401H is also used in medical imaging, robotics, and other high-temperature equipment, all while providing reliable temperature protection.

P5010D135S401H Thermal Switch Working Principle

The P5010D135S401H is a thermal switch with a temperature limit that automatically activates or deactivates devices depending on thermal conditions. This is done through two paired junctions connected in series on the chip, each of which has a different temperature sensitivity. One junction is sensitive to low temperatures and will become conductive at lower temperatures while the other junction is sensitive to higher temperatures, and will become conductive at higher temperatures. The temperature limit at which the switch operates is determined by the resistance between the two junctions.

The thermal switch works by using the two paired junctions to detect temperatures that are outside the programmed temperature range, and will then activate the tested devices to either increase or decrease the temperature. If the temperature rises above the set limit, the switch will switch off the device in order to reduce the temperature, while if the temperature falls below the set limit, the switch will switch on the device in order to increase the temperature.

The major advantage of using the P5010D135S401H chip is that it requires no calibration, and provides reliable temperature protection for high-end applications. The chip is also capable of providing accurate temperature protection for a wide range of temperatures, making it suitable for many areas.
