In today’s era of booming electronic products, battery safety has become a core concern for consumers and manufacturers alike. As a key component in the battery management system, the safety and reliability of the battery management system (BMS) directly determines the quality and reputation of the end product. To meet the specific needs of BMSs, Lute Technology offers low-resistance resettable fuses in 0805 and 1206 package sizes, with current holding ranges from 1.5A to 4A and voltage withstand values from 6V to 16V. These fuses perfectly meet the safety protection needs of various lithium-ion batteries, polymer batteries, and energy storage battery packs.
In battery protection board applications, overcurrent and short-circuit protection are crucial safety links. The working principle of the resettable fuse is that when an abnormal overcurrent occurs in the circuit, its own impedance increases rapidly, thereby effectively limiting the current and cutting off the circuit. When the fault is eliminated and the power is disconnected, the PPTC component automatically cools down and returns to a low-resistance state, without the need for manual replacement, which greatly improves the maintainability and user experience of the product and reduces production and after-sales costs. Compared with standard PPTC products, LuTe Technology’s low-resistance resettable fuse can achieve higher holding current in a smaller size and thinner package, while maintaining the excellent electrical characteristics and performance of standard PPTC products, while providing ultra-low internal resistance characteristics. Its 0805 and 1206 packages are small and compact, making them very suitable for high-density battery protection board designs with limited space. Precise current grading from 1.5A, 3A, to 4A, along with a wide range of withstand voltage options, including 6V, 9V, 12V, and 16V, allows engineers to precisely select the appropriate model for battery packs of varying capacities and string counts (e.g., power tools, smart wearables, Bluetooth headsets, power banks, portable medical devices, etc.), ensuring a quick and accurate response to any anomalies.
LuTe Technology’s resettable fuses feature low internal resistance, fast trip time, and long cycle life. They effectively prevent overheating, fire, and even explosion hazards caused by faults such as overcharge, over-discharge, and external short circuits, comprehensively enhancing the safety level of end products. All products comply with environmental directives such as RoHS and REACH and are certified for quality management systems, ensuring reliable quality. Choosing LuTe Technology means choosing not only a reliable component but also a trusted safety partner. We provide comprehensive technical support and sample services to help your battery products become more competitive in the market.
