Product Description

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.
Non-operating current:
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
Actuation time:
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
