YQD120N0010

Overview

The YQD120N0010 is a ceramic PTC resettable fuse manufactured by Amphenol Advanced Sensors. It features a nominal resistance of 10 ohms with a tolerance of ±25%. The component supports a maximum voltage of 265V and a maximum current rating of 1.8 A, with a hold current (Ih) of 250 mA. Designed for through-hole radial mounting, it utilizes tin-coated copper lead wires. The device operates within standard industrial temperature ranges and is supplied in bulk packaging.

Feature Summary

• Provides automatic circuit protection against overcurrent conditions via positive temperature coefficient characteristics
• Functions as a self-resetting safety device eliminating the need for manual fuse replacement after fault clearance
• Constructed from ceramic materials ensuring durability and stable electrical performance under thermal stress

Applications

• Overcurrent protection in consumer electronic devices
• Circuit safeguarding in industrial control systems
• Power supply input protection for low-voltage applications

Procurement Notes

Verify the specific datasheet version to confirm exact trip times and residual voltage characteristics for your circuit design. Ensure the radial lead spacing matches your PCB footprint requirements. Confirm that the 265V maximum voltage rating exceeds your system's peak operating voltage to prevent dielectric breakdown during transient events.

Selection Notes

Select this component when a self-resetting protection mechanism is preferred over traditional fuses. The 10-ohm baseline resistance and 250 mA hold current define the operating window. Consider the physical size constraints due to the disc form factor. Validate thermal dissipation capabilities in enclosed environments to ensure reliable tripping behavior.

Part Context

This part belongs to the YQ series of PTC thermistors from Amphenol Advanced Sensors. The series is designed for general-purpose circuit protection. It complements other components in the manufacturer's portfolio focused on thermal management and safety. The radial package facilitates easy integration into standard manufacturing processes.

Replacement Considerations

The YQZ120N1.00 shares the same YQ series family but differs significantly in resistance value and current ratings. Verify compatibility before substitution as electrical parameters are not interchangeable. No direct equivalent part numbers are publicly confirmed for identical specifications.
