YQS8070

Overview

The YQS8070 is a radial leaded PTC resettable fuse manufactured by Amphenol Advanced Sensors under the Thermometrics brand. It features a ceramic construction with a nominal resistance of 600 ohms and a maximum voltage rating of 265V. The device operates within a temperature range of 0°C to +55°C and has a hold current of 22mA with a trip current of 40mA. Physical dimensions include a diameter of 4.00mm and a height of 5.00mm, with a lead spacing of 5.00mm.

Feature Summary

Provides overcurrent protection through automatic reset functionality upon fault removal
Utilizes ceramic technology for stable thermal performance in circuit applications
Designed for through-hole mounting with radial leads for PCB integration

Applications

Overcurrent protection in electronic circuits
Battery pack protection systems
Consumer electronics power input stages

Procurement Notes

Verify the specific series designation (YM) and tolerance requirements against official datasheets before procurement. Confirm that the operating environment remains within the specified 0°C to +55°C range to ensure reliable tripping characteristics. Ensure the selected component matches the required hold and trip current specifications for the target application circuit design.

Selection Notes

Select this component when a resettable fuse with a 600-ohm baseline resistance is required. Consider the 265V maximum voltage rating and 22mA hold current limits during circuit design. Evaluate the physical footprint constraints regarding the 4.00mm diameter and 5.00mm height for PCB layout compatibility.
