PTC Resettable Fuses, also known as a polyfuse or a positive temperature coefficient fuse, are one of the most common forms of overcurrent protection. They are used to protect circuits from short-circuits and surges, and can detect and limit current flow. The PTR016V0700-BK1 is a plastic encapsulated PTC Resettable Fuse from Bourns with a voltage rating of 16V. This PTC fuse has a fast operating time of 1s or less.

The PTR016V0700-BK1 is designed for use in automotive, industrial, and communications systems. It can provide over-current protection for a variety of applications, from motor drives and power converters, to Inverters and chargers. The PTC is also suitable for protecting sensitive circuits from surge current events. It is designed for harsh environments, and is UL approved for use in the US and Canada.

The PTR016V0700-BK1 has a current rating of 700mA, with a trip threshold current of 1.3 x I/N (I = rated current, N = rated current + 30%). At the rated current, the PTC provides fast operating time, and provides an LED indication when the fuse trips.

The working principle of a PTC Resettable Fuse is based on the electrical, thermal, and mechanical properties of a polymeric material. This material is heat sensitive, and acts as a resistor when current passes through it. When excessive current passes through the material, it heats up, increasing its resistance. This causes a continuous rise in temperature and eventually causes the material to melt, thus interrupting the current flow. After the fault condition is cleared, the material cools down and returns back to its original state.

The PTR016V0700-BK1 is a reliable and cost-effective device for a variety of applications. It has a fast response time, is easy to install and maintain, and provides overcurrent protection in a wide range of environments. Additionally, its resettable feature allows it to be used multiple times without the need to replace it. This makes the PTC Resettable Fuse a great option for protecting valuable devices and circuits from damage in the event of an electrical surge.
