with its unique design concept and manufacturing process, the self recovering fuses (PPTC) from Jidian Electric have demonstrated the following core advantages in the market:
Excellent reliability and stability:
Core material advantages: Jidian usually uses high-quality polymer matrices and highly conductive fillers, optimized formulas and processing techniques to ensure that its PPTC products maintain extremely low resistance (internal resistance) under normal working conditions, reducing power loss and heat generation.
Accurate action characteristics: The product has precise triggering current (` Ihold `/` Itrip `) and action time characteristics, which can respond quickly and reliably in the event of overcurrent or short circuit in the circuit, effectively protecting sensitive electronic components.
Excellent voltage resistance: The product design focuses on dielectric strength and voltage resistance, which can withstand high open circuit voltage after protective action, prevent breakdown failure, and improve the overall safety of the system.
Long service life: Under rated working conditions, it can withstand multiple overcurrent protection recovery cycles with slow performance degradation, providing long-lasting circuit protection.
Fast response and protection performance:
Optimization for different scenarios: Jidian provides a variety of response speed product lines (such as standard type, fast break type, etc.) to meet the protection speed requirements of different application scenarios. For precision circuits or data line protection that require quick disconnection, their quick disconnect products perform excellently.
Thermal coupling optimization: The design focuses on the thermal coupling efficiency between PPTC components and protected circuits/components, enabling faster sensing of temperature rise and action in the event of a fault.
Miniaturization and low internal resistance design:
Adapting to high-density PCBs: Following the trend of miniaturization in electronic devices, Jidian provides a wide range of surface mount (SMD) package sizes (such as 0402, 0603, 0805, 1206, etc.), occupying minimal PCB space, especially suitable for portable devices and compact circuit board designs with limited space.
Low internal resistance advantage: Through continuous improvement in material technology and structural design, its PPTC achieves lower initial resistance (Rmin) while maintaining a small volume, effectively reducing voltage drop and power loss during normal operation, improving system efficiency, and reducing unnecessary temperature rise.
Wide product selection and flexibility:
Wide parameter coverage: Provides a wide range of holding current (` Ihold `), rated voltage (` Vmax `), and action time, covering circuit protection needs in many fields from consumer electronics (such as USB ports, battery packs), communication equipment, industrial control to automotive electronics (compliant with relevant standards).
Diverse packaging forms: In addition to mainstream SMD packaging, we also offer different packaging forms such as radial leads (plugs), disks, modules, etc., to meet the requirements of different installation methods and application scenarios.
High cost-effectiveness and localized service advantages:
Cost competitiveness: Relying on the advantages of localized production and supply chain management, Jidian can usually provide more competitive prices while ensuring product performance and reliability, effectively controlling costs for customers, especially in large-scale applications where the advantages are obvious.
Agile technical support and services: As a domestic brand, we are able to provide faster and more customer-centric technical support, sample requests, and customized services (within feasible limits), with faster response times and smoother communication.
In summary, the core advantage of Jidian's self recovery fuse lies in its ability to meet the needs of modern electronic devices through miniaturization and low internal resistance design, while ensuring high reliability and precise protection. With a rich product line, it provides flexible solutions and, combined with localized high cost-effectiveness and agile services, offers engineers an excellent and cost-effective option for circuit overcurrent protection.
