The RUILON SMD2920 Series Positive Thermal Coefficient (PTC) resettable fuses are high-power overcurrent protection devices designed for demanding electronic and industrial applications. These components automatically increase resistance during fault conditions, effectively limiting current flow and protecting sensitive circuitry from damage caused by short circuits, overloads, or surge events.

With a larger 2920 SMD footprint, this series offers higher current handling capability, improved thermal stability, and reliable self-resetting performance, making it ideal for power-intensive systems.

🔹 Key Features

• High current resettable overcurrent protection (PTC technology)
• Large 2920 SMD package for higher power handling
• Fast response to overload and short-circuit conditions
• Stable trip characteristics and reliable reset behavior
• Low resistance during normal operation
• Automatic recovery after fault removal
• High durability for repeated surge events

🔹 Applications

• Power supply and adapter protection
• Battery management systems (high current)
• Industrial automation equipment
• Telecom and networking power lines
• Automotive electronic protection circuits
• Motor control and power modules
• PCB-level overcurrent safety protection
