Overview
The YQZ120N1.80 is a PTC thermistor manufactured by Amphenol Advanced Sensors (Thermometrics). It belongs to the YQ series and features a resistance of 1.8 ohms with a tolerance of 25%. The component utilizes radial leads for PCB mounting and operates within a temperature range of 0°C to +60°C. It has a current rating of 650 mA and is supplied in bulk packaging.
Feature Summary
- Radially-wired construction with green silicone resin coating
- RoHS compliant design
- Standard tolerance configuration
Applications
- Circuit protection applications
- Overcurrent protection circuits
- Temperature sensing in low-temperature environments
Procurement Notes
Verify the specific resistance value and tolerance against the official datasheet, as variations exist within the YQ series. Confirm that the operating temperature range of 0°C to +60°C aligns with your application requirements. Ensure the radial lead style is compatible with your PCB layout and assembly process.
Selection Notes
Select this component when a low-resistance PTC thermistor is required for circuit protection or sensing. Consider the 650 mA current rating and the specific 0°C to +60°C operating window. Compare with other YQ series variants if different resistance values or higher temperature ratings are needed.
Part Context
This part is part of the Thermometrics YQ series of PTC thermistors. These components are characterized by their radially-wired design and green silicone resin coating. They are designed for standard tolerance applications and comply with RoHS standards, fitting into the broader category of industrial sensors and circuit protection devices offered by Amphenol Advanced Sensors.
Replacement Considerations
Other parts in the YQ series may serve as substitutes if they share similar radial mounting and silicone coating characteristics. Verify electrical parameters such as resistance and current rating before substitution.
