PTC Resettable Fuses are widely used in electronic products and are applied in various industries, such as computers, automobiles, audio-visual products, household appliances, etc. YPCL0150T is one type of PTC Resettable Fuses, which has lots of advantages, such as fast response, reliable operation, wide range of voltage regulation, and much more. PTC Resettable Fuses is now commonly used to provide over-current protection, under-voltage protection, over-voltage protection, without-load protection and earth fault protection.

YPCL0150T is a self-recovery type of over-voltage protector. When the voltage reaches or exceeds its rated voltage level, the fuse element will break down. The normal grounding current flows through another grounding ring and the thermal release element connection point and then to the ground. The over-current generated by the device is absorbed by the fuse element, causing it to heat up and melt. During melting, it cuts off the over-voltage protection circuit.

When the rated voltage is restored, the reset process of YPCL0150T automatically begins. After the temperature gradually decreases, the fuse element cools down and restores itself from the previous state. This process can repeat itself many times, allowing YPCL0150T to provide a type of “open protective” functionality. As the temperature increases, the heat-release element connected at the grounded point will break down and pass the current when the operating voltage is zero.

The current flow of YPCL0150T gradually decreases when the supply voltage reaches its rated voltage. Since PTC resettable fuses, such as YPCL0150T, can cut off the current flow, it can effectively protect the system from over-current and over-voltage. YPCL0150T can be applied in many areas, such as power supplies, automotive systems, sensors, circuits, home appliances and many others.

In terms of working principle, the YPCL0150T has the typical operating characteristics of a PTC fuse. The fuse element of the YPCL0150T is composed of a PTC polyvinyl carbazole material (often referred to as PTC) and copper wire. When the rated operating voltage is reached, it immediately cuts off the current due to the increase in the temperature of the PTC material. When the temperature reaches the melting point of the PTC material, the fuse element melts, causing the circuit to break. The current passing through the PTC material is reduced by the weakening of the conducting material, and the temperature also gradually decreases as the current decreases.

The resetting process of YPCL0150T is very fast and efficient. After the temperature of PTC material decreases, the current flow through the PTC will gradually increase, and the fuse element will return to its former state. When the operating voltage reaches the set voltage level, the resetting process is complete.

In conclusion, YPCL0150T is a self-resetting type of PTC resettablefuse, which has wide application fields and working principle. YPCL0150T can provide over-current protection, under-voltage protection, over-voltage protection, without-load protection and earth fault protection. With its fast response, reliable operation, and wide range of voltage regulation, YPCL0150T is widely used in different industries and electronic products.
