Radial Leaded Polymer Switch PTC Resettable Fuse 6V 1.2A For Computer And Multimedia

Description Of The Polymer Switch PTC Resettable Fuse 6V 1.2A

A: JK6 series PTC self-recovery fuses have a rated working voltage of 6-16V and a rated holding current of 0.75A-3.0A. The series products are suitable for circuits with low working voltage and relatively small working current, such as computers, computer peripheral toy industries, etc. field.

B: JK6 series of Polymer PTC self-resettable fuse (Polymer PTC Restoring Fuse) is a new-generation of overcurrent protection product, its function corresponds to the self-resettable and repeatedly-usable fuse,being used to protect circuit from damage by high current and having such superiorities as automatic reset,high security, short restoring time, fine performance of low resistance to strong current as well as little volume.they can be used in communication exchanger, main distributing frame, computer mouse, keyboard, micromotor,transformer, audio, battery and other electrical equipment as well as circuits, to play the role overcurrent protection.

C: The resistance of PTCs rises as the temperature rises. With this feature, the value change of resistance is not obvious when the safe current passes, the resistance value changes drastically when abnormal current passes, this reaches the purpose of limiting abnormal current, the resistance value will “reset” automatically when the abnormality is eliminated and temperature returns to a safe level . It is an ideal choice for equipment with frequent abnormal over-current flowing area. PPTC often used in consumer electronics, power lines, telecommunications, I/O connectors, process control and medical equipment.

Selection Methods Polymer Switch PTC Resettable Fuse 6V 1.2A

Using the following methods can help you select the suitable JKPPTC resettable fuses:
1. List the average working current (I) and voltage (V.) of the circuit.
2. Select the JKPPTC series according to the I, V , product’s type and the form of installation.
3. If the inner temperature of device is over 25°C, the current through the JKPPTC element will decrease along with the temperature rise. The holding current can calculate as follows according to discount rate: IH=operating current (I) ÷ discount rate .
4. According to the JKPPTC series ,which selected in step 2 and the IH calculated in step 3,choose the proper element in the catalogue,the IH of the selected JKPPTC must be equal or greater than the IH calculated in step 3.
If there is any demand for room temperature resistance and the operation time of overcurrent protection on the line use the above method to select relevant series.
5. If you need some special products and can not find the relevant element in our products table,please contact us,we will make a free special development for your need.
