YQD120N0025

Overview

The YQD120N0025 is a PTC reset fuse manufactured by Amphenol Advanced Sensors (Thermometrics). It features a ceramic construction with a nominal resistance of 25 ohms and a diameter of 9mm. The component has a 20% tolerance rating and operates as a radial lead device. It is designed for circuit protection applications requiring resettable fuse functionality.

Feature Summary

Provides overcurrent protection through positive temperature coefficient behavior
Features self-resetting capability after fault condition removal
Utilizes ceramic material for robust thermal stability

Applications

Circuit protection in electronic assemblies
Overcurrent safeguarding in power supply lines
Resettable fuse implementation in consumer electronics

Procurement Notes

Verify the specific voltage and current ratings against application requirements before procurement. Confirm that the radial lead configuration matches the PCB layout constraints. Ensure the ceramic package type aligns with thermal management needs. Cross-reference the 25-ohm nominal resistance with circuit design specifications to guarantee proper operation within the intended system parameters.

Selection Notes

Select this component when a resettable fuse solution is required for overcurrent protection. Consider the 25-ohm resistance value for minimal impact on normal circuit operation. Evaluate the 9mm diameter for available board space. Verify compatibility with the 265V rating if used in higher voltage environments. Assess the need for automatic recovery after fault clearance versus one-time fuse replacement.

Part Context

This part belongs to the Thermometrics line from Amphenol Advanced Sensors, specializing in temperature sensing and protection components. The YQ series represents their range of PTC thermistors designed for resettable fuse applications. These components are distinct from standard NTC thermistors used primarily for temperature measurement, focusing instead on circuit protection functions.
