Resettable Protectors for USB Type-C Connectors & Batteries - China Factory Suppliers for Overheat Protection

USB Type-C connectors are becoming increasingly popular in smartphones, tablet PCs, notebooks, power banks, smart wearables, and other devices. The sleek design and capabilities, such as up to 100W power transmission and reversible plug orientation, offer users significant advantages. However, overheating issues in connectors can lead to dangerous situations, including smoke and even fire hazards. Foreign objects like metal shavings, water stains, or hair can create micro-short circuits between Vbus and GND in the narrow needle design of these connectors. This highlights the critical need for Type-C overheating protection. Lucky Pioneer, a leading factory in China, has introduced innovative overheating protection solutions, including SBP and PPTC, ensuring safety and reliability for your devices. As trusted suppliers in the industry, we prioritize the durability and functionality of USB Type-C connectors

    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-in. However, connector overheating often occurs during use and can easily lead 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)
    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 industries, and other fields. When an unusually large current occurs in the circuit, the heat generated by the PPTC product increases sharply, and the internal resistance limits the circuit current to a minimum level in a short time, avoiding damage to other components and preventing danger. The protection effect is close to that of a one-time melting fuse, but with self-recovery characteristics — once the abnormal circuit is resolved, the PPTC product's resistance returns to its initial level in a short period of time, and the circuit returns to normal.

    Product Characteristics
    • Compact product design
    • Ultra-low resistance
    • Over-temperature and over-current dual protection
    Frequently Asked Questions
    What is a Small Battery Protector (SBP) and how does it work?
    The Small Battery Protector (SBP) is a thermal protection device designed for USB Type-C connectors. It monitors the temperature of the connector in real time and activates protection when overheating is detected — preventing smoke, burning, or damage caused by micro-short circuits from foreign bodies such as metal shavings, water, or debris inside the connector.
    Is the SBP compatible with 100W fast-charging circuits?
    Yes. The SBP is specifically designed to be compatible with 100W power circuits, making it suitable for high-power USB Type-C applications including laptops, tablets, and fast-charging power banks.
    What is PPTC and what makes it different from a standard fuse?
    PPTC (Polymeric Positive Temperature Coefficient) is a resettable overcurrent and over-temperature protection component. Unlike a standard one-time fuse that must be replaced after tripping, PPTC automatically recovers and restores its low resistance state once the fault condition is removed, allowing the circuit to return to normal operation without replacement.
    In which industries and applications are PPTC components commonly used?
    PPTC components are widely used across a broad range of industries including telecommunications, consumer electronics, computers, multimedia devices, battery packs, industrial equipment, and the automotive industry — anywhere that electric transient current protection is required.
    Can SBP and PPTC be used together in the same circuit?
    Yes. Lucky Pioneer offers both SBP and PPTC as a combined overheating protection solution. Using them together provides dual protection — the SBP handles thermal protection at the connector level, while the PPTC protects the broader circuit from overcurrent and over-temperature events.
    How many protection cycles can the SBP withstand?
    The SBP is engineered for durability and can withstand thousands of protection cycles, ensuring long-term reliability in devices that frequently experience temperature fluctuations or connector stress during daily charging and data transfer use.
