YQD120N0070

Overview

The YQD120N0070 is a PTC disc thermistor manufactured by Amphenol Advanced Sensors (Thermometrics). It features a nominal resistance of 70 ohms at 25°C with a tolerance of ±25%. The device operates within a temperature range of 0°C to 60°C. Physical dimensions include a diameter of 6.5 mm and a thickness of 5.00 mm, mounted on tin-coated copper lead wires with a spacing of 5 mm. Electrical ratings specify a maximum voltage of 265V, a maximum current of 300mA, a hold current (Ih) of 65mA, and a trip current (It) of 130mA.

Feature Summary

Positive Temperature Coefficient (PTC) behavior for circuit protection
Resettable fuse functionality upon cooling
Disc form factor with axial leads

Applications

Overcurrent protection in electronic circuits
Self-regulating heating elements
Motor start assistance

Procurement Notes

Verify the specific electrical parameters against the official datasheet before integration. Confirm that the operating environment remains within the 0°C to 60°C range to ensure proper function. Check lead wire specifications and physical mounting requirements for compatibility with the target PCB or assembly design.

Selection Notes

Select this component when a resettable overcurrent protection device is required with a 70-ohm baseline resistance. Ensure the application current does not exceed the 300mA maximum rating. Consider the thermal environment constraints relative to the specified operating temperature range.

Part Context

This part belongs to the YQ series of PTC thermistors from Thermometrics. These components are designed for applications requiring reliable, resettable protection or self-regulation. The series offers various resistance values and physical sizes to suit different circuit requirements.
