YS5678

Overview

YS5678 is a PTC resettable fuse manufactured by Amphenol Advanced Sensors (Thermometrics). It features a radial disc package designed for through-hole mounting. The component functions as a current protection device, providing overcurrent protection in electronic circuits. As a positive temperature coefficient thermistor, it automatically resets after the fault condition is cleared and the device cools down.

Feature Summary

Provides automatic circuit protection against overcurrent conditions
Self-resetting functionality eliminates the need for manual replacement after fault clearance
Radial disc form factor enables standard through-hole PCB integration

Applications

Overcurrent protection in consumer electronics assemblies
Circuit safeguarding in industrial control systems
Protection of power supply inputs in automotive applications

Procurement Notes

Verify the specific trip current and hold current ratings required for your application against the official datasheet specifications. Confirm that the radial lead spacing matches your PCB footprint design. Ensure the voltage rating meets the maximum operating voltage of the protected circuit to prevent dielectric breakdown during normal operation or transient events.

Selection Notes

Select this component when a self-resetting protection mechanism is preferred over traditional fuses to maintain system availability. Consider the thermal environment of the installation site, as ambient temperature affects the holding current performance. Evaluate the maximum fault current capability to ensure the device can safely interrupt the fault without damage.

Part Context

This part belongs to the Thermometrics line of advanced sensors and protection devices from Amphenol. The YS series specifically addresses thermal management and circuit protection needs. These components are engineered for reliability in demanding environments, supporting various industrial and commercial electronic applications requiring robust overcurrent safeguards.
