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

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.
