PTC Resettable Fuses are a key part of the power supply system. This system is designed to protect the power supply from overload and over temperature. A PTC resettable fuse is a type of fuse that when the current reaches a certain threshold, the fuse heats up and trips. It then needs to be manually reset in order to be used again. The specific model PTGL09AS7R6K6B51A0 is a type of polymeric positive temperature coefficient (PPTC) of resettable fuse.

Application Field

The PTGL09AS7R6K6B51A0 PTC fuse is used in a wide range of applications, such as automotive electronics, consumer electronics, computers, telecommunications, industrial automation, medical devices and automotive charging systems. It can also be used in AC/DC general-purpose circuit protection for low voltage, high current applications. The features and small size of the PTC makes it useful for applications where space is limited.

Working Principle

The PTGL09AS7R6K6B51A0 PTC Resettable Fuse uses a solid-state material which has a positive temperature coefficient of resistance (PTCR), meaning that when the current through the material increases, the resistance of the material also increases. This creates a self-regulating thermal switch which is designed to trip and open the circuit when the current reaches the trip point. After the current is reduced, the thermal switch will reset itself and the fuse will reset itself to the original resistance once the temperature of the device is below the reset level.

When the current through the PTC exceeds the rated value, the heat increases dramatically, causing the resistance to increase proportionally. The high resistance limits the current and prevents damage to the power supply source or connected devices. The reset time of the device depends on the temperature of the environment, as well as the load conditions.

The PTGL09AS7R6K6B51A0 PTC Resettable Fuse offers a number of advantages over other types of fuses. The device has a lower initial cost, as well as a much longer life span since it can be reset multiple times. The device is also smaller in size than most other types of fuses. In addition, the device offers a much faster response time to any fault, making it ideal for applications where safety is a priority.

The PTGL09AS7R6K6B51A0 PTC Resettable Fuse is a reliable and affordable way to protect equipment against over current and/or over temperature. The device provides a reliable and safe way to protect power supplies and connected devices from damage. The device is easy to install and use, and is perfect for use in a wide range of applications, including automotive electronics, consumer electronics, industrial automation, medical devices and automotive charging systems.
