YQS5876PTF

Overview

The YQS5876PTF is a radial-wired PTC thermistor from the Thermometrics PTF series, functioning as a solid-state resettable fuse. It operates at a voltage of 240 V with a width of 6.9 mm. The component supports an operating temperature range from +10°C to +55°C and is supplied in bulk packaging.

Feature Summary

• Functions as a low-cost solid-state resettable fuse
• Utilizes bare PTC disc thermistor technology
• Features radial wire leads for through-hole mounting

Applications

• Overcurrent protection circuits
• Electronic device thermal management
• Resettable fuse applications

Procurement Notes

Verify the specific datasheet version for precise trip current and hold current ratings, as these are critical for circuit protection design. Confirm that the radial lead configuration matches the target PCB layout requirements. Ensure the maximum operating temperature of +55°C aligns with the environmental conditions of the intended application to prevent premature tripping or failure during normal operation.

Selection Notes

Select this component when a cost-effective, non-latching overcurrent protection solution is required. The radial form factor simplifies assembly compared to surface-mount alternatives. Consider the 240 V rating for compatibility with mains-connected or high-voltage auxiliary circuits. Evaluate the thermal environment to ensure the +55°C limit is not exceeded under steady-state load conditions.

Part Context

This part belongs to the Amphenol Advanced Sensors (Thermometrics) PTF series, which specializes in radially-wired bare PTC disc thermistors. The series is designed to provide reliable, low-cost solid-state fusing capabilities for various electronic systems, distinguishing it from standard NTC temperature sensors within the same manufacturer portfolio.
