Designed for overcurrent protection, this component operates at rated voltages of 100V and 120V. It features a hold current specification of 5A and a trip current of 10A. The device utilizes a standard package configuration suitable for surface mount or through-hole integration in electronic circuits requiring reliable thermal and electrical safety mechanisms.
Feature Summary
- Provides automatic circuit recovery after fault clearance without manual replacement
- Offers dual voltage rating capability for versatile application integration
- Features a coated construction to enhance environmental durability
Applications
- Consumer electronics power supply protection
- Industrial control system circuit safeguarding
- Battery pack overcurrent prevention
Procurement Notes
Verify the specific voltage rating requirement (100V or 120V) against the target circuit design before procurement. Confirm that the hold current and trip current specifications align with the operational parameters of the protected load. Ensure compatibility with the manufacturing process regarding the coated finish and mounting method. Cross-reference the manufacturer's latest datasheet for any updates on compliance standards or mechanical dimensions prior to finalizing the purchase order.
Selection Notes
Select this component when a self-resetting protection mechanism is required for low-voltage DC or AC circuits. Consider the thermal environment of the installation site, as ambient temperature affects the trip characteristics of PTC devices. Evaluate the physical space constraints to ensure the standard package fits the PCB layout. Compare the response time and maximum current capacity against alternative fuses to determine if the resettable nature provides a distinct advantage for the specific application lifecycle.
Part Context
This part belongs to the YQS5 series of PTC resettable fuses from Amphenol Advanced Sensors. This series is engineered for general-purpose overcurrent protection in various electronic assemblies. The product line emphasizes reliability and ease of use in consumer and industrial applications where repeated fault events may occur, reducing maintenance costs associated with traditional one-time fuses.
Replacement Considerations
Direct substitutes must match the 100/120V rating and 5A hold current. Verify that alternative components offer similar trip current characteristics and compatible mounting styles. Ensure that any replacement maintains the same safety certifications and coating properties for environmental resistance.
