PTC Resettable Fuses are invaluable components in many electrical systems, providing short-circuit protection by disrupting current flow while still allowing a restart after the fault has been cleared. The PTGL09AR4R7M3B51A0 is at the leading edge of PTC Resettable Fuses technology, providing overcurrent protection in lower voltage applications.

Application Field

The PTGL09AR4R7M3B51A0 is designed for voltage conditions between 6-32 volts hertz AC or DC. It is most commonly used to protect low voltage circuits in automobiles, consumer electronics, medical equipment, computers, and other low-voltage applications. Its versatile design allows it to be implemented easily and quickly in new and existing systems, saving time and money.

Working Principle

The PTGL09AR4R7M3B51A0 is a type of polymeric positive temperature coefficient thermal (PPTC) switch. This means that the device, when activated, shifts its resistance to an infinite value, effectively stopping current flow. When the fault is cleared, the device returns to its low resistance state, allowing current to flow once again. The process is temperature-dependent which avoids unreliable mechanical resetting. The device is self-regulating, so it can sense different temperature levels and self-reset at whichever level it was triggered at.

The PTGL09AR4R7M3B51A0 is designed with a range of current ratings. In general, it is rated at a power dissipation up to 0.15W and can carry a current up to 0.8A. It features reliable switching and quick response times, typically around one second. It is also accurate and self-resetting, meaning it requires no manual intervention and can act as a failsafe to protect your systems.

Safety Features

Safety is a key concern with any electrical system, and the PTGL09AR4R7M3B51A0 allows for the highest degree of safety available on the market. Its robust design meets established UL94V-0 and CSA standards for fire and flammability, and it can be used in devices up to class II. In addition, the device is highly resistant to moisture and corrosion, and its construction protects against electrical shock.

The PTGL09AR4R7M3B51A0 is an excellent choice for any application where overcurrent protection is needed. Its state-of-the-art design makes it a reliable and economical solution to a wide range of low voltage applications.
