PTC Resettable Fuses, also known as Polymeric Positive Temperature Coefficient (PPTC) fuses, provide unique protection for electronic devices and optimizing product life frequency. PTGL07AR250H4B51A0 is a PTC Resettable Fuse designed specifically for handheld applications, offering superior performance in terms of current protection, power protection, and temperature specification.

The application field of PTGL07AR250H4B51A0 is mainly intended to use in the low-voltage electrical products of handheld devices such as digital cameras, portable music players, and cordless phones, and medical devices, as well as industrial application such as industrial controllers, power supply circuit boards, lighting fixtures, and automotive application. These fuses offer an ideal way to protect devices against hazardous currents.

The working principle of the PTGL07AR250H4B51A0 is based on the characteristic of the PPTC Resettable Fuse features of self-restoring characteristics. When thermal energy builds up in the PPTC Resettable Fuse as the current increases beyond the rated current, its resistance increases rapidly, sharply reducing the current flow and creating a zener-like effect. This significantly reduces the risk of overheating and other equipment-damaging conditions.

PTGL07AR250H4B51A0 offers a wide selection of mounting options for various electrical and electronic applications, making it easy to install and maintain. It also features a small profile with low insertion force that requires minimal space. The integrated design supports easy design-in, and its superior heat-dissipating construction allows for maximum protection of other application components.

In addition, PTGL07AR250H4B51A0 features a wide variety of current ratings and reset voltages, so it can be used in various applications. This provides designers with greater flexibility when selecting components for their designs. Its reset current ranges from 5A to 20A, and its reset voltage ranges from 0.08 to 0.2V.

Integrated with a Controlled Surge Current Capability (CSCC) feature, the PTGL07AR250H4B51A0 can accurately detect and protect against short-term surges and is designed to protect devices even in harsh environments. It is also designed with a wide operating temperature range from -40°C to 85°C, ensuring reliable performance in even the most demanding applications.

Overall, PTGL07AR250H4B51A0 is a reliable, easy-to-use PTC Resettable Fuse that provides superior current protection, power protection, and temperature specifications for handheld device applications. With its small profile, easy installation, and wide selection of current ratings and reset voltages, it is an ideal choice for both small and larger applications.
