MF-R005-0-99

Ptc Resettable Fuses Overview

The Bourns MF-R005-0-99 is a resettable polymeric positive temperature coefficient (PPTC) device from the MF-R Series. It functions as a self-resetting overcurrent protector designed to safeguard electronic circuits against excessive current conditions. The component utilizes a polymer composite that increases resistance significantly upon heating, thereby limiting current flow until the fault is removed and the device cools down.

Ptc Resettable Fuses Feature Summary

• Self-resetting functionality eliminates the need for manual replacement after an overcurrent event.
• Polymer composite construction provides reliable trip characteristics under sustained overload conditions.
• Compact form factor allows for integration into space-constrained circuit board layouts.

Ptc Resettable Fuses Applications

• Portable electronic devices requiring battery protection
• Consumer electronics circuit boards
• Industrial control system input/output modules

Ptc Resettable Fuses Procurement Notes

Verify the specific suffix code against official manufacturer documentation to confirm exact holding current and trip parameters. Ensure the selected variant matches the required voltage rating and package style for the target application. Cross-reference the part number with the latest datasheet revision to avoid discrepancies in electrical specifications or compliance status.

Ptc Resettable Fuses Selection Notes

Select this component based on the required hold current and maximum operating voltage for the specific circuit design. Evaluate the thermal environment of the installation site to ensure proper heat dissipation. Confirm that the device's time-current characteristics align with the protection requirements of the downstream sensitive components without causing nuisance tripping during normal operation.

Ptc Resettable Fuses Part Context

This part belongs to the MF-R Series of PPTC devices manufactured by Bourns Inc.
