China Suppliers Factory: Resettable Protectors for USB Type-C Connectors & Battery Overheat Protection Solutions
Small Battery Protector (SBP)
Product Description:
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 — however, connector overheat issues frequently occur during use, easily leading to smoke or even burning. For example, foreign bodies such as metal shavings, water stains, or hair inside the narrow-pin connector can cause Vbus and GND to form a micro-short circuit. Therefore, Type-C overheat protection has become very necessary. Lucky Pioneer has launched both SBP and PPTC overheating protection solutions.
★ Product Characteristics
- Accurate temperature protection
- Thousands of protection cycles
- Compatible with 100W power circuits
Electric Transient Current Protection Components (PPTC)
Product Description:
PPTC products are a kind of electric transient current protection component, widely used in telecommunications, consumer electronics, computers, multimedia, batteries, industrial automotive, and other fields. PPTC products are connected in series in the circuit. When an unusually large current occurs, the heat generated by the PPTC products increases sharply, limiting the circuit current at a minimum level within a short time — avoiding damage to other components and preventing dangerous situations. The protection effect is close to a one-time melting fuse, but with self-recovery characteristics. Once the abnormal circuit fault is cleared, the resistance of the PPTC product returns to the initial level in a short period of time, restoring the circuit to normal operation.
★ Product Characteristics
- Compact product design
- Ultra-low resistance
- Over-temperature and over-current dual protection
Frequently Asked Questions (FAQ)
Q
What is the main function of the Small Battery Protector (SBP)?
The SBP is designed to protect USB Type-C connectors from overheating. It monitors the temperature of the connector and triggers protection when abnormal heat is detected, preventing potential smoke or fire hazards caused by micro-short circuits from foreign bodies or improper use.
Q
What types of devices are compatible with the SBP solution?
The SBP solution is compatible with a wide range of devices that use USB Type-C connectors, including smartphones, tablet PCs, notebooks, power banks, and smart wearable devices. It supports power circuits up to 100W.
Q
How does a PPTC component protect a circuit from overcurrent damage?
When an abnormally large current flows through the circuit, the PPTC component generates heat rapidly, causing its internal resistance to increase sharply. This limits the current to a very low level, effectively protecting other circuit components from damage — similar in effect to a fuse, but without the need for replacement.
Q
Does the PPTC component need to be replaced after it triggers protection?
No. Unlike traditional fuses, PPTC components feature a self-recovery characteristic. Once the abnormal condition is resolved and the circuit returns to normal, the PPTC's resistance automatically recovers to its initial level within a short period of time, restoring normal circuit operation.
Q
What industries commonly use PPTC protection components?
PPTC components are widely applied across multiple industries, including telecommunications, consumer electronics, computers, multimedia devices, battery systems, industrial equipment, and the automotive industry — anywhere that requires reliable transient overcurrent protection.
Q
What are the key differences between the SBP and PPTC protection solutions?
The SBP (Small Battery Protector) focuses primarily on temperature-based overheat protection for USB Type-C connectors, offering accurate thermal monitoring and thousands of reusable protection cycles. The PPTC solution, on the other hand, provides dual protection against both over-temperature and overcurrent conditions, featuring ultra-low resistance and a compact design suitable for broader circuit protection applications.
