PTC Resettable Fuses have been created to provide safe current protection in a variety of electrical circuits in the industrial, commercial, consumer, and automotive markets. The 1210L150PR is a medium power, cost-effective PTC Resettable Fuse used to protect devices from both over-voltage and over-current conditions. It is designed to OCP or OVP circuit applications from 2A-10A.

Application Field
The 1210L150PR is the ideal choice for mobile communication systems such as phones, cameras, and portable devices. Its low profile with little to no power dissipation allows it to be used in multiple portable applications. It is also suitable for high power LED lighting designs. It also has the ability to be used in automotive powertrain, application while providing efficient overload protection.

Working Principle
The 1210L150PR utilizes a polymeric Positive Temperature Coefficient (PPTC) material which acts as the electrical switch. When the current going through the device exceeds a certain value (Ihold), the PPTC material will heat up and act to open or close the circuit depending on the application. This action lowers the current and it can only be reset once the temperature has dropped enough. For this reason, PTC Resettable Fuses are also known as “self-resetting” or “self-recovering” fuses.

The 1210L150PR is an ideal choice for applications that require reliable current protection and the ability to reset after an over-current event. It is designed with an extremely tractable response and rejections that greatly reduce nuisance tripping. The device provides superior protection and maintains flexibility in installation.

Overall, the 1210L150PR is a versatile, cost-effective, and reliable PTC Resettable Fuse for a variety of applications. It protects from both over-voltage and over-current conditions in LED lighting designs, handheld devices, and automotive powertrain applications. The device is designed with a rapid response time, minimal power dissipation, and superior protection at an affordable cost.
