MF-RX135-AP-99

Ptc Resettable Fuses Overview

The MF-RX135-AP-99 is a resettable fuse from Bourns' Multifuse series, designed for overcurrent protection in electronic circuits. It features an axial leaded package with a thermoplastic housing and tin-plated copper leads. The device operates by increasing resistance when excessive current flows, generating heat that triggers a phase change to a high-resistance state. Once the fault is removed and the unit cools, it resets to its original low-resistance state automatically.

Ptc Resettable Fuses Feature Summary

• Automatic reset functionality eliminates the need for manual replacement after fault clearance.
• High reliability and long service life under normal operating conditions.
• Compact axial leaded design suitable for through-hole mounting applications.

Ptc Resettable Fuses Applications

• Overcurrent protection in consumer electronics
• Circuit protection in industrial control systems
• Battery pack protection in portable devices

Ptc Resettable Fuses Procurement Notes

Verify the specific suffix 'AP-99' against the official Bourns datasheet to confirm packaging details and compliance status. Ensure the selected variant matches the required voltage and current ratings for the target application. Cross-reference the part number with the manufacturer's latest documentation to avoid obsolete or discontinued stock issues.

Ptc Resettable Fuses Selection Notes

Select this component based on the circuit's maximum operating voltage and continuous current requirements. Ensure the trip current rating exceeds the normal operating current while remaining below the fault threshold. Consider the ambient temperature range and thermal dissipation capabilities of the PCB layout to guarantee reliable performance during overcurrent events.

Ptc Resettable Fuses Part Context

This part belongs to Bourns' Multifuse family of resettable fuses, which are widely used for circuit protection. The series offers various packages and ratings to suit different application needs. These devices provide a cost-effective alternative to traditional fusible links by offering automatic recovery from fault conditions without requiring physical intervention.

Ptc Resettable Fuses Replacement Considerations

Consult the official Bourns substitution guide for compatible alternatives. Verify that any substitute part matches the electrical characteristics, including holding current, trip current, and maximum voltage. Ensure the replacement component fits the existing footprint and meets all regulatory requirements for the end product.
