PTC resettable fuses provide circuit protection for electronic devices from the harmful effects of electrical surges and sudden increases in current. The MF-USHT050KX-2 is a PTC resettable fuse with overcurrent and overtemperature protection. It is a reliable and cost-efficient way to protect sensitive electronic components from damage caused by excessive current or temperature fluctuations.

The MF-USHT050KX-2 is typically used in consumer products such as personal computers, cell phones, digital cameras, and other portable electronic devices. It is also used in automotive, medical, and industrial applications. The fuse is designed to detect both temperature and overcurrent events and respond accordingly. When a current surge or temperature increase is detected, the PTC resettable fuse will trip, interrupting the current and protecting the device from further damage.

The MF-USHT050KX-2 has a rated current of 0.5A and a reset current of 0.2A. Its operating voltage is 5V, with a maximum voltage of 10V. It has a maximum ambient temperature of 85°C and a reset operation temperature of 75°C. At these temperatures, the fuse will trip and reset within 1 to 5 seconds. It also has a maximum overload capacity of 1.2 times its rated current.

The working principle of the MF-USHT050KX-2 is straightforward and highly reliable. The fuse is a semiconductor device made up of a positive temperature coefficient (PTC) material. The PTC material increases in resistance with increasing temperature, which allows it to detect and respond to overcurrent and overtemperature events. When an overcurrent or overtemperature event is detected, the PTC material increases in resistance and prevents current flow. This trips the fuse, and the current flow is interrupted.

Once the temperature decreases or the overcurrent event subsides, the PTC material returns to its original state and the fuse will reset. The MF-USHT050KX-2 is designed to reset quickly and reliably, protecting circuits even when exposed to frequent current surges or temperature fluctuations.

The MF-USHT050KX-2 PTC resettable fuse offers a highly reliable and cost-effective way of protecting sensitive electronic components from current surges and temperature fluctuations. It is an ideal choice for consumer, automotive, medical, and industrial applications, and provides reliable overcurrent and overtemperature protection.
