PTGL05AR181M7P52A0

PTC Resettable Fuses are a form of overcurrent protection that combine small physical size with reliability and low-cost. They are basically components that limit and detect a current above the rated value for protection purposes and eventually trip after a certain period of time to protect against any further overcurrent.

The PTGL05AR181M7P52A0 is a popular PTC Resettable Fuse that is specifically used for electro-magnetic interference (EMI) filtering applications. It provides instantaneous detection of fault conditions and features an internal fast action to limit current surges or faults, while providing quick recovery. The PTGL05AR181M7P52A0 is designed to protect against potentially hazardous fault conditions and meet the requirements of products such as personal computers, computer peripherals, consumer electronics, automotive circuit boards, and telecommunication systems.

The PTGL05AR181M7P52A0 is a two-terminal, open-style, temperature-stable, self-resetting PTC fuse. It is available in various package sizes, ranging from 0805 to 2917. It has a current rating of 1A and a rated voltage of 127V. The fuse has a response time of 10ms, a resistance of 39.8mOhms, and a power dissipation of 1.2W. The approximate dimensions in millimeters for the 0805 package are 2.0Lx1.25Wx0.90H.

The PTGL05AR181M7P52A0 works using the principle of positive temperature coefficient (PTC) technology. When the current passing through the fuse exceeds the rated current, the resistance of the fuse rises dramatically, thus limiting the current flowing through it. The PTC element instantly trips at the rated current. After some time has passed, the resistance of the fuse returns to its nominal value. This allows the element to be recycled for further protection against overcurrent.

The PTGL05AR181M7P52A0 is used in various applications including power supplies, automotive, network equipment, telecom, and audio/video. It is widely used to act as a surge protector, preventing currents that exceed its rated value from occurring. It is also used as a protection device to protect against short-circuiting and other effects of current surges. Additionally, it is used as a current limiter in applications such as electro-magnetic interference (EMI) filters.

In summary, the PTGL05AR181M7P52A0 is a two-terminal, open-style, temperature-stable, self-resetting PTC fuse. It is specifically used for electro-magnetic interference (EMI) filtering applications as a surge protector, current limiter, and protection device. It features an internal fast action that limits current surges and faults, while providing quick recovery. The PTGL05AR181M7P52A0 is widely used in various applications such as power supplies, automotive, network equipment, telecom, and audio/video.
