• Utilizes radial lead mounting for printed circuit board integration

Applications

• Consumer electronics power supply protection
• Industrial control circuit safeguarding
• Automotive electrical system overcurrent prevention

Procurement Notes

Verify the specific YM series designation and radial package configuration against official Amphenol documentation. Confirm that the 300 Ohm resistance value and 265V rating align with the target application requirements before procurement.

Selection Notes

Select this component when a resettable overcurrent protection mechanism is required for low-current applications. Ensure the operating environment supports the thermal characteristics necessary for the PTC switching action to function correctly within the circuit design.

Part Context

This part belongs to the YM series of PTC thermistors manufactured by Amphenol Advanced Sensors (Thermometrics). The series focuses on providing reliable circuit protection solutions using polymer-based positive temperature coefficient materials for various industrial and consumer applications.

Replacement Considerations

Cross-reference with other YM series radial PTC thermistors having similar 300 Ohm resistance and 265V ratings. Verify mechanical footprint compatibility and thermal response times to ensure equivalent performance in the existing assembly.
