Overview
The YQS8066 is a Positive Temperature Coefficient (PTC) thermistor manufactured by Amphenol Advanced Sensors. This component features a resistance of 1 kilohm at standard conditions with a tolerance of 20%. It is rated for an RMS voltage of 265V and has a current rating of 128 mA. The device operates within a temperature range of 0°C to 55°C. It utilizes a radial disc package configuration designed for through-hole mounting, suitable for industrial circuit protection applications.
Feature Summary
- Positive Temperature Coefficient (PTC) behavior for overcurrent protection
- Radial disc form factor for through-hole integration
- High voltage rating capability up to 265V RMS
Applications
- Overcurrent protection in electronic circuits
- Self-resetting fuse replacement
- Industrial control system components
Procurement Notes
Verify the specific datasheet version for precise switching characteristics and hold current parameters before integration. Confirm that the 128 mA current rating aligns with the target circuit requirements. Ensure the 0°C to 55°C operating range meets environmental constraints. Check RoHS compliance status if required by project specifications.
Selection Notes
Select this component when a self-resetting PTC fuse is required for low-current DC or AC line protection. The 1kOhm baseline resistance and 265V RMS rating define its electrical boundaries. Consider the radial disc package for standard PCB drilling patterns. Evaluate thermal dissipation needs relative to the 128 mA limit.
Part Context
This part belongs to the Amphenol Advanced Sensors portfolio, specifically under their sensor and protection component lines. Amphenol designs interconnect systems and sensors for demanding regulatory applications. The YQS8066 represents a standard discrete protection element within their broader industrial offering.
Replacement Considerations
Cross-reference with other radial PTC thermistors from Amphenol or competitors having matching 1kOhm resistance and 265V RMS ratings. Verify identical current ratings of 128 mA and compatible operating temperature ranges for direct substitution.
