Resettable Overheat Protectors for USB Type-C Connectors & Batteries - China Suppliers & Factory Solutions
USB Type-C connectors have been increasingly widely used in smartphones, Tablet PCs, notebooks, power banks, smart wearables, and other devices. Users benefit from its thin shape, up to 100W power transmission, and support for forward and reverse plug advantages. However, overheating of the connector often leads to smoke or even burning during use. For example, once foreign bodies such as metal shavings, water stains, or hair enter the connector's narrow needle design, they can cause Vbus and GND to form a micro-short circuit. Therefore, Type-C overheat protection becomes very necessary. Lucky Pioneer has launched both the SBP and PPTC overheating protection solutions.
- Accurate temperature protection
- Thousands of protection cycles
- Compatible with 100W power circuits
PPTC is a type of electric transient current protection component, widely used in telecommunications, consumer electronics, computers, multimedia, batteries, industrial automotive industries, and other fields. Connected in series within a circuit, when an unusually large current occurs, the heat generated by the PPTC product increases sharply. The internal resistance limits the circuit current to a minimum level in a short time, avoiding damage to other components and preventing hazards. The protection effect is similar to a one-time fuse, but with a self-recovery characteristic — once the abnormal circuit issue is resolved, the PPTC resistance returns to its initial level in a short period, restoring the circuit to normal operation.
- Compact product
