PTCCL05H111FTE

Ptc Resettable Fuses Overview

The PTCCL05H111FTE is a ceramic PTC resettable fuse manufactured by Vishay BC Components. It features a radial leaded, disc package designed for through-hole mounting. The device has a maximum DC voltage rating of 145V and a hold current (Ih) of 110 mA. Its trip current (It) is specified at 220 mA, with a maximum fault current capacity of 500 mA. The resistance at 25°C is typically 40 Ohms with a tolerance of 20%. The component operates within a temperature range of 0°C to +70°C and measures 10 mm in height.

Ptc Resettable Fuses Feature Summary

• Provides automatic circuit protection against overcurrent conditions by increasing resistance when heated.
• Features a self-resetting mechanism that restores conductivity after the fault condition is removed and the device cools down.
• Constructed from ceramic materials to ensure stability and reliability in overload protection applications.

Ptc Resettable Fuses Applications

• Overload protection for electronic circuits
• Current limiting in power supply lines
• Protection of sensitive components against short circuits

Ptc Resettable Fuses Procurement Notes

Verify the specific suffix FTE against the official Vishay datasheet to confirm lead plating and packaging specifications. Ensure the selected variant matches the required hold current and voltage ratings for the target application. Cross-reference the manufacturer part number with authorized distributors to confirm authenticity and compliance with RoHS standards.

Ptc Resettable Fuses Selection Notes

Select this component based on the 110 mA hold current requirement and 145 VDC maximum voltage rating. Consider the 40 Ohm initial resistance and 500 mA maximum fault current capability. Evaluate the thermal environment to ensure operation remains within the 0°C to +70°C range. Confirm that the radial through-hole package fits the PCB layout constraints.

Ptc Resettable Fuses Part Context

Ptc Resettable Fuses FAQ

What is the difference between hold current and trip current for this device?

Hold current (110 mA) is the maximum current the device can carry without tripping. Trip current (220 mA) is the minimum current that causes the device to switch to a high-resistance state.

Can this component be used in place of a traditional fuse?

Yes, it serves as a resettable alternative to traditional fuses, providing overcurrent protection that automatically resets after cooling.
