YQD100N0150

Overview

The YQD100N0150 is a PTC reset fuse manufactured by Amphenol Advanced Sensors under the Thermometrics brand. It features a radial disc package with a resistance of 150 Ohms at 25°C and a tolerance of ±25%. The component has a rated RMS voltage of 230 V, a maximum operating voltage of 265 V, and a maximum withstanding voltage of 350 V. It includes a current rating of 22 mA and is RoHS compliant.

Feature Summary

• Provides overcurrent protection through positive temperature coefficient behavior
• Functions as a resettable fuse for circuit safeguarding
• Utilizes a radial leaded disc form factor for through-hole mounting

Applications

• Consumer electronics power supply circuits
• Industrial control system protection
• AC line input filtering stages

Procurement Notes

Verify the specific thermal environment requirements against the component's trip characteristics before procurement. Confirm that the radial lead configuration matches the target PCB layout constraints. Ensure the 265 V maximum operating voltage rating exceeds the peak line voltage present in the application to prevent premature failure or insulation breakdown during normal operation.

Selection Notes

Select this component when a resettable overcurrent protection device is required for AC mains applications. The 150 Ohm initial resistance and 22 mA current rating define the holding current threshold. Consider the physical size of the radial disc package for space-constrained designs. Validate that the 350 V withstanding voltage provides adequate safety margin for the specific network topology.

Part Context

This part belongs to the YQD series of PTC thermistors from Amphenol Advanced Sensors. These components are designed for high-reliability applications requiring automatic reset after fault conditions. The Thermometrics branding indicates specialized sensor and protection technology within the Amphenol portfolio.

Replacement Considerations

Cross-reference other YQD series variants with matching 150 Ohm resistance and 265 V ratings. Verify that substitute parts maintain identical radial lead spacing and voltage withstand capabilities to ensure mechanical and electrical compatibility without redesign.
