Designed for reliable circuit protection, the Polymer PPTC PTC Resettable Fuse JK250-080U 80mA provides consistent performance for applications up to 250V. It responds quickly to overcurrent events by temporarily limiting current flow and then returns to its original state once normal conditions resume, enabling automatic recovery without replacement.
80mA holding current for precise current limiting of sensitive electronic components.
250V voltage rating suitable for a wide range of electrical applications.
Low resistance to minimize power loss and reduce heat during normal operation.
Polymer-based construction that delivers durable reset capability over multiple fault cycles.
Compact size for easy integration into various circuit designs without occupying excessive space.
Compared with traditional single-use fuses, the JK250-080U resettable fuse eliminates the need for replacement after a trip, reducing maintenance time and long-term cost. The polymer PTC technology used in this device offers rapid reaction to overcurrent conditions and improved endurance in demanding electrical environments. Its design increases resistance quickly when current exceeds safe levels, protecting circuits from damage, and then returns to a low resistance state after the fault is cleared, supporting repeated protection cycles and reliable long-term operation.
