FRU800-30F

Ptc Resettable Fuses Overview

The FRU800-30F is a radial leaded PTC resettable fuse belonging to the FRU series, manufactured by RFE International and Fuzetec. This component functions as a polymeric positive temperature coefficient device designed for overcurrent protection in electronic circuits. It utilizes a conductive polymer composite that transitions from a low-resistance state to a high-resistance state upon excessive current flow or elevated temperature. The device automatically resets to its original low-resistance state once the fault condition is removed and the unit cools down, providing reusable circuit protection without requiring manual replacement.

Ptc Resettable Fuses Feature Summary

• Provides automatic circuit recovery after overcurrent events
• Utilizes conductive polymer technology for rapid response
• Features radial leaded construction for through-hole mounting

Ptc Resettable Fuses Applications

• Overcurrent protection for portable electronic devices
• Circuit safeguarding in consumer audio equipment
• Protection of battery-powered appliance power inputs

Ptc Resettable Fuses Procurement Notes

Verify the specific manufacturer designation, as both RFE International and Fuzetec produce components under this part number format. Confirm that the procurement source provides official datasheets detailing the hold current, trip current, and maximum voltage ratings. Ensure the supplier can authenticate the component origin to distinguish between potential variations in material composition or manufacturing standards across different producers.

Ptc Resettable Fuses Selection Notes

Select this component based on the required holding current and trip current specifications for the target application circuit. Evaluate the maximum voltage rating to ensure it exceeds the system's operating voltage. Consider the physical size constraints imposed by the radial leaded package and verify compatibility with standard through-hole assembly processes. Assess the thermal environment to ensure the device maintains reliable performance under expected operating temperatures.

Ptc Resettable Fuses Part Context

The FRU800-30F belongs to the FRU series of resettable fuses, which are widely used for protecting sensitive electronics from damage due to short circuits or overloads. These devices serve as an alternative to traditional one-time fuses by offering repeated use. The series is characterized by its compact radial leaded form factor, making it suitable for space-constrained applications where reliable, self-resetting protection is required.
