Overview
The YQS5898PTO is an uncoated PTC thermistor from the Amphenol Advanced Sensors (Thermometrics) product line. It features a switching temperature of 120°C and a resistance of 25 ohms at 25°C. The component utilizes a radial leaded termination style for PCB mounting. It is supplied in bulk packaging, with a standard factory quantity of 1000 units per reel or tube as indicated by similar series data.
Feature Summary
- Uncoated construction for direct thermal contact
- Positive temperature coefficient behavior for overcurrent protection
- Radial leaded configuration for through-hole mounting
Applications
- Overcurrent protection circuits
- Self-resetting fuse applications
- Temperature sensing interfaces
Procurement Notes
Verify the specific switching current rating against the official datasheet before integration. Confirm that the uncoated body material is compatible with the target assembly environment. Ensure the radial lead spacing matches the printed circuit board layout requirements to prevent mechanical stress during soldering.
Selection Notes
Select this component when a self-resetting protection mechanism is required at 120°C. The 25-ohm baseline resistance suits low-voltage signal lines. Compare holding current specifications against other PTO series variants to ensure adequate margin for normal operating conditions without nuisance tripping.
Part Context
This part belongs to the Thermometrics PTC thermistor family manufactured by Amphenol Advanced Sensors. It serves as a passive electronic component designed for circuit protection. The PTO suffix typically denotes specific lead and coating variations within the broader product portfolio.
Replacement Considerations
Consult the manufacturer's cross-reference guide for verified substitutes. Generic equivalents may differ in switching tolerance or physical dimensions.
