Ptc Resettable Fuses Procurement Notes
Verify the specific electrical parameters against the official datasheet before integration. Confirm that the 120V rating and 120mA hold current align with the target circuit requirements. Check for availability status as this part may be classified as obsolete or end-of-life by the manufacturer.
Ptc Resettable Fuses Selection Notes
Select this component when a radial PTC fuse with a 120V maximum voltage is required. Ensure the circuit's normal operating current remains below the 120mA hold current threshold to prevent nuisance tripping. Verify that the 50Ω initial resistance is compatible with the system's startup characteristics.
Ptc Resettable Fuses Part Context
This device belongs to the Thermometrics line of PTC resettable fuses from Amphenol Advanced Sensors. These components are designed for surface mount or through-hole applications where reliable overcurrent protection is critical. The series offers various voltage and current ratings to suit different industrial and consumer electronics needs.
Ptc Resettable Fuses Replacement Considerations
Consult the manufacturer's official substitution guide for direct replacements. Verify that any alternative part matches the 120V voltage rating, 120mA hold current, and radial disc form factor to ensure mechanical and electrical compatibility.
