FRG400-16F

Ptc Resettable Fuses Overview

The FRG400-16F is a radial leaded PTC resettable fuse from the FRG series, designed for through-hole mounting. It features a maximum voltage rating of 16V and a hold current (Ih) of 4A. The device has a maximum initial resistance of 20 mOhms and a maximum post-trip resistance of 63 mOhms. It supports a maximum trip current of 100A with a maximum time to trip of 3.5 seconds. The component operates within a temperature range of -40°C to +85°C and dissipates up to 2.4W. The lead spacing is 5.10mm.

Ptc Resettable Fuses Feature Summary

• Provides automatic circuit protection against overcurrent conditions by increasing resistance when tripped.
• Resettable functionality allows restoration of normal operation after fault clearance without replacement.
• Radial leaded package design facilitates standard through-hole PCB mounting processes.

Ptc Resettable Fuses Applications

• Overcurrent protection in consumer electronics circuits
• Battery pack protection systems
• Peripheral interface port safeguarding

Ptc Resettable Fuses Procurement Notes

Verify that the specific part number matches the required electrical ratings, particularly the 16V voltage limit and 4A hold current. Confirm the radial lead spacing of 5.10mm aligns with the target PCB footprint. Ensure the operating temperature range of -40°C to +85°C meets the environmental requirements of the final assembly. Cross-reference manufacturer documentation to confirm compliance with safety standards applicable to the end product.

Ptc Resettable Fuses Selection Notes

Select this component when a low-voltage, high-current resettable fuse is required for through-hole applications. The 4A hold current and 16V rating suit low-power digital circuits. Consider the 3.5-second trip time for applications tolerant of brief overcurrent events. Evaluate the thermal dissipation characteristics relative to surrounding components on the PCB layout.
