- Motor startup assistance
Procurement Notes
Verify availability status as the YQS8068 is listed as obsolete or discontinued in public records. Confirm end-of-life status with the manufacturer before design finalization. Check for valid RoHS compliance documentation if required for specific regulatory environments. Ensure replacement components meet identical electrical and mechanical specifications.
Selection Notes
Select this component when a 100 Ohm PTC characteristic is required for circuit protection or sensing. Verify that the 65 mA current rating aligns with the application's operational limits. Consider the radial package size for board space constraints. Evaluate thermal performance within the specified 0°C to +55°C operating range.
Part Context
The YQS8068 belongs to the YM series of PTC thermistors produced by Amphenol Advanced Sensors under its Thermometrics brand. This series is designed for general-purpose electronic protection and sensing tasks. The component represents a standard discrete solution for managing current surges and monitoring temperature in consumer and industrial electronics.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided data. Consult Amphenol Advanced Sensors directly for recommended cross-reference parts. Ensure any alternative component matches the 100 Ohm resistance, 65 mA rating, and radial form factor.
