YQD100N150

Overview

The YQD100N150 is a PTC resettable fuse manufactured by Amphenol Advanced Sensors under the Thermometrics brand. It features a radial disc form factor designed for through-hole mounting applications. The component operates within an ambient temperature range of 0°C to 60°C. It provides circuit protection with a voltage rating of 265V. The device utilizes a lead spacing of 5.10mm (0.201 inches). This part belongs to the YQD100 series, serving as a reusable overcurrent protection solution for electronic circuits requiring reliable thermal cutoff capabilities.

Feature Summary

• Provides reusable overcurrent and overtemperature protection via positive temperature coefficient characteristics
• Features a radial disc package design suitable for standard through-hole PCB mounting processes
• Maintains stable performance within a defined operating temperature range of 0°C to 60°C

Applications

• Consumer electronics power supply input protection
• Battery pack overcurrent safeguarding
• General industrial control board circuit protection

Procurement Notes

Verify the specific datasheet revision when sourcing, as electrical characteristics such as trip current and hold current may vary between manufacturing batches. Confirm that the required voltage rating of 265V aligns with your system's maximum potential. Ensure the operating environment stays within the 0°C to 60°C limit to guarantee proper reset functionality and longevity of the protective element.

Selection Notes

Select this component when a self-resetting protection mechanism is preferred over single-use fuses to reduce maintenance requirements. The radial disc style facilitates automated insertion or manual assembly on standard printed circuit boards. Consider the thermal environment carefully, as the device relies on ambient heat dissipation to trip; high ambient temperatures near the upper limit may affect response times.

Part Context

This component is part of the Thermometrics YQD100 series, which focuses on compact, surface-mountable or through-hole resettable fuses. The brand specializes in sensor technologies and measurement solutions, extending into protective components for harsh environments. The YQD100N150 specifically addresses needs for reliable, non-latching protection in space-constrained electronic assemblies.

Replacement Considerations

Direct substitutes must match the 265V rating and radial disc footprint. Verify that alternative PTC fuses from other manufacturers support similar hold and trip currents. Ensure the replacement component also accommodates the 0°C to 60°C operational range without derating issues.
