PTC Resettable Fuses have been widely used around the world in all kinds of industries and applications, ranging from consumer electronics to industrial equipment. HVR250P180UF is one of the most popular PTC resettable fuses, and it has excellent over-current, over-temperature and over-voltage protection performance.

HVR250P180UF application field includes automotive electronics, industrial equipment, home appliances, telecommunications systems, computer peripheral devices, and more. HVR250P180UF is especially suitable for automotive electronics and industrial equipment due to its high current carrying capability, excellent over-voltage protection, and high temperature resistance.

The working principle of the HVR250P180UF is as follows: when the current through the fuse is greater than the rated current, the thermal reaction temperature of the PTC element will be higher than the rated temperature, and the internal resistance will increase suddenly. This will generate a large amount of heat to reduce the current, thereby protecting the circuit or equipment from over-current damage.

Further, when the operating temperature of the HVR250P180UF reaches its rated thermal temperature, the internal PTC element will start to conduct the over-current away from the circuitry, thus protecting the equipment from damage. When the temperature returns to its normal status, the PTC element will reset automatically, and the fuse can return to its normal operation.

In addition, HVR250P180UF also offers excellent over-voltage protection. It is equipped with two sets of internal resistors, which cooperate with the PTC element to form a voltage regulation circuit. When the external voltage exceeds its rated value, the contacts of the voltage regulation circuit will open, thus protecting the equipment from over-voltage damage.

Furthermore, HVR250P180UF has excellent high temperature resistant capability. It is capable of withstanding up to 125℃ operating temperature, and it can still operate stably in high temperature environment. HVR250P180UF also has a wide operating voltage range, making it suitable for all kinds of equipment and applications.

In summary, HVR250P180UF is one of the most popular PTC resettable fuses, and it is widely used in automotive electronics, industrial equipment, home appliances, telecommunications systems, computer peripheral devices, and more. The HVR250P180UF has excellent over-current, over-temperature and over-voltage protection performance, making it an ideal choice for any application that requires reliable protection against these types of hazards.
