Polymer Positive Temperature Coefficient PTC Thermistor 6V-600V With TUV UL IATF 16949 Approval
Fundamental Of The Positive Temperature Coefficient PTC Thermistor 6V-600V
Polymer PTC stands for "Polymer Positive Temperature Coefficient Thermistor", which has excellent overcurrent protection function due to the special properties of its material. The polymer PTC is connected in series in the circuit (as shown in Figure 1). Under normal circumstances, it is in a low resistance state and the working current can pass smoothly; when an abnormally large current appears in the circuit, its impedance increases rapidly (in a high resistance state) ), which effectively restricts the passage of large currents and protects the circuit from damage (see Figure 2). When the fault current is eliminated, the resistance of the polymer PTC drops rapidly and returns to a low resistance state.
Features Of The Positive Temperature Coefficient PTC Thermistor 6V-600V
* Low-resistance, small in size,wide working current
* Overcurrent and over-temperature protection are fast
* The initial state can be automatically restored after troubleshooting.
Application Of The Positive Temperature Coefficient PTC Thermistor 6V-600V
It is widely used in circuits with medium withstand voltage capability, such as micro-motors, computer interfaces, mice, CPUs, transformers, security equipment, test and measurement equipment, satellite receiving systems, toy industries and other fields.
Computer and peripheral equipment, mobile phone,
Batteries, telecommunication and network equipment, transformers.
Industrial control equipment, automobile and other electronic products

Terminology Of The Positive Temperature Coefficient PTC Thermistor 6V-600V
| Non-operating current: | Rated current or holding current, Refers to the current that does not cause the value of PPTC thermistor to exceed the specified range under specified time and temperature conditions. |
| Action current: | The current that increases the resistance of PPTC thermistors in a step - up manner |
| Trigger current: | Minimum action current |
| Actuation time: | When the action current passes PPTC, the time it takes for the current to fall from the initial value to the lower limit value |
| Action characteristics: | The relationship between PPTC action current and action time |
| Voltage resistance: | The capacity of PPTC to withstand the specified maximum power frequency voltage |
| Current resistance: | Capacity of PPTC to withstand specified maximum power frequency current or shock current |
| Operating power: | The maximum power consumed by PPTC in its operating state |
| Rmin: | Minimum resistance at 25 C |
| Rmax: | Max resistance at 25 C |
Typical Time To Trip at 25+/-2 deg
Selection guide Of The Positive Temperature Coefficient PTC Thermistor 6V-600V
The use of polymer PTC is safe and convenient, and is a win-win strategy. When selecting, first consider that the working voltage should be less than or equal to the maximum voltage that the polymer PTC can follow; secondly, match the size of the working current. The working current (IH) listed in the specification refers to the current value when the working environment temperature is 25℃ If the actual working environment temperature is different from it, the temperature and current reduction factors should also be considered. Refer to Figure 3 for details. Finally, the installation method (such as plug-in, optical film insertion) must be considered. For other technical indicators, please refer to the specification. If you have any special circumstances, please contact our company directly for special processing.

Working principle Of The Positive Temperature Coefficient PTC Thermistor 6V-600V
Positive Temperature Coefficient PTC Thermistor is composed of specially treated polymer resin (Polymer) and conductive particles (CarbonBlack) distributed in it. Under normal operation, the polymer resin tightly binds the conductive particles outside the crystalline structure to form a chain-like conductive electrical path. At this time, the resettable fuse is in a low resistance state (a), and the current flows through the resettable fuse. The heat energy is small and will not change the crystal structure. When the circuit is short-circuited or overloaded, the heat generated by the large current flowing through the self-recovery fuse melts the polymer resin, and the volume increases rapidly to form a high-resistance state (b), and the operating current decreases rapidly, thereby limiting and protecting the circuit. When the fault is eliminated, the resettable fuse cools and crystallizes again, the volume shrinks, the conductive particles form a conductive path again, and the resettable fuse returns to a low resistance state, thus completing the protection of the circuit without manual replacement.
