YS5675

Overview

The YS5675 is a PTC thermistor manufactured by Amphenol Advanced Sensors under the Thermometrics brand. It belongs to the YS series and is designed for PCB mount applications with radial termination. The component features a nominal resistance of 25 ohms at 25°C with a tolerance of 20%. It is supplied in bulk packaging.

Feature Summary

• Positive temperature coefficient behavior for circuit protection
• Radial leaded construction for through-hole mounting
• Bulk packaging format for high-volume assembly

Applications

• Overcurrent protection circuits
• Self-resetting fuse applications
• Temperature sensing elements

Procurement Notes

Verify the specific datasheet for the YS5675 to confirm detailed electrical characteristics such as trip current, hold current, and maximum voltage ratings. Ensure the 20% resistance tolerance aligns with design requirements. Confirm that the bulk packaging quantity matches production needs. Check RoHS compliance status if required by project specifications.

Selection Notes

Select this component when a self-resetting overcurrent protection device with low resistance is required. The 25-ohm value suits applications needing minimal voltage drop during normal operation. Consider the radial package for standard PCB layouts. Evaluate thermal performance against ambient conditions to ensure reliable tripping behavior.

Part Context

This part is part of the YS series of PTC thermistors from Amphenol Advanced Sensors. It serves as a resettable fuse alternative to traditional fuses. The product falls under the broader category of environmental sensors and thermistors within the manufacturer's portfolio.

Replacement Considerations

Consult official substitution lists for equivalent PTC thermistors with similar resistance and tolerance values. Verify pin compatibility and thermal characteristics before replacing.
