Ptc Resettable Fuses Procurement Notes

Verify the exact part number against official Murata documentation due to potential suffix variations affecting packaging or tolerance. Confirm availability status as distribution channels may list obsolete or discontinued inventory. Ensure the specified voltage and current ratings match the target application requirements before procurement to avoid performance mismatches.

Ptc Resettable Fuses Selection Notes

Select this component for low-voltage branches requiring high hold currents with minimal power loss. Compare the 1.5 mΩ resistance against standard PTCs to ensure compatibility with sensitive load voltages. Validate that the radial through-hole package fits the PCB layout constraints and that the 60 V rating exceeds the system's peak operating voltage.

Ptc Resettable Fuses Part Context

This part belongs to the POSISTOR PTGL series, designed for general-purpose overcurrent protection. It complements other PTGL variants by offering higher current capacity with lower resistance. The series is widely used in automotive and industrial sectors where reliable, reusable protection is critical for maintaining system uptime during transient faults.
