PPTC Description Of The PTC Thermistor 60V 72V 1.35A FRX135-60F PPTC Reset Fuse

AFT Polymeric Positive Temperature Coefficient (PPTC) devices are used to help protect against harmful
overcurrent surges and overtemperature faults. Like traditional fuses, these devices limit the flow of
dangerously high current during fault conditions. The PolySwitch device, however, resets after the fault is
cleared and power to the circuit is removed, thereby reducing warranty, service and repair costs.

Working Principle of PPTC Device

Polymeric PTC material and devices technology synergistically integrate the advanced polymer material
technologies, conductive material science, novel processing engineering, and fundamental electronic and
electrical theory. Electrical resistance of such material and devices increases with temperature increases and
vice versa. When experiencing “overcurrent and/or over voltage”, the device generates thermal energy
(Energy = I*V) and heats up itself. This makes the polymer matrix’s morphology change from crystalline to
amorphous phase, and results in a resistance increase of thousand orders of magnitude such that “trips” the
electricity. The device will remain hot and stay “tripped” until the fault is cleared and power is removed.

Selection Guide Of The PTC Thermistor 60V 72V 1.35A FRX135-60F PPTC Reset Fuse

SMD fuses are mainly used in electronic products such as digital cameras, notebooks, and mobile phones.

From traditional glass tube fuses to miniature fuses and chip fuses, due to the differences in product technology,

the focus of their selection is slightly different. The selection of chip fuses involves the following factors:

1. Normal working current of the circuit

2. Pulse, inrush current, surge current, starting current and circuit transient value

3. The magnitude of the overload current of the circuit and the shortest and shortest time of the overload current

4. Resistance

5. Ambient temperature of the fuse

6. Applied voltage applied to the fuse

7. Product certification
