PTC resettable fuses, also known as polyfuses, are electrical protection devices used to protect electric circuits from damage caused by overcurrents. The PTR016V0185-BK is a resettable fuse designed to protect circuits from temporarily high current demands. It is a two-position device consisting of a PTC element and a holder. When the current surpasses the tripping current of the PTC element, it will be tripped and break the circuit. When the overcurrent situation is cleared, the PTC element can be reset by simply pushing down the holder until the clicking sound is heard.

Application Field

The PTR016V0185-BK is commonly used in industrial control systems, intelligent instrumentation and vehicular electronics. It can also be used as over-current protection in consumer electronic products, such as mobile phones, laptops, digital cameras, MP3 players, and tablet PCs.

Working Principle

The PTR016V0185-BK uses a PTC element to protect circuits from overcurrent. The PTC element consists of a ceramic body and a pair of conductive internal leads. Its tripping current is marked on the inner surface of the holder. When overcurrent flows through the device, the temperature of the PTC increases rapidly, causing it to become resistive, thus increasing the resistance to the tripping current. The heat causes the material to melt, deforming the ceramic body and separating the internal leads, thereby breaking the circuit and preventing further overcurrent.

When the source of the overcurrent is eliminated, the temperature of the PTC element diminishes and the device can be reset by pushing the holder down. This will cause the PTC element to return to its previous shape, thus closing the circuit again.

In conclusion, the PTR016V0185-BK is a resettable fuse designed for use in a wide variety of applications. Its working principle is based on the PTC element, which is responsible for sensing overcurrent, dissipating the heat generated by the overcurrent, and tripping the circuit when a predetermined current is exceeded. Therefore, the PTR016V0185-BK is perfect for industrial and vehicular applications in need of efficient overcurrent protection.
