TL4050B10QDCKR

Overview

The TL4050B10QDCKR is a precision micropower shunt voltage reference manufactured by Texas Instruments. It provides a fixed output voltage of 10V with an initial accuracy of ±0.2%. The device features a temperature coefficient of 50ppm/°C and supports a maximum shunt current of 15mA. It operates within a temperature range of -40°C to +125°C and is housed in a SC-70-5 surface-mount package.

Feature Summary

• Precision micropower shunt voltage reference design
• High initial accuracy for stable reference performance
• Automotive qualification compliant with AEC-Q100 standards

Applications

• Automotive electronic systems requiring precise voltage references
• Data acquisition systems needing high stability
• Industrial control circuits utilizing shunt regulation

Procurement Notes

Verify the specific suffix 'Q' indicates automotive grade qualification (AEC-Q100) distinct from standard industrial variants. Confirm the package type matches the SC-70-5 footprint requirements for your PCB layout. Ensure the 10V output voltage aligns with your system's reference needs, as this model is fixed and not adjustable.

Selection Notes

Select this component when automotive reliability and high precision are required in a compact form factor. The 10V output is suitable for applications needing higher reference levels without external scaling. Consider the 50ppm/°C temperature coefficient for thermal stability requirements across the extended operating temperature range.

Part Context

This part belongs to the TL4050 family of precision voltage references. The 'B' designation typically denotes the ±0.2% accuracy class, while 'Q' signifies automotive qualification. The 'DCKR' suffix identifies the SC-70-5 package and reel packaging configuration used for surface-mount assembly processes.

Replacement Considerations

TL4050B10IDCKR serves as the industrial-grade equivalent with identical electrical specifications but lacks automotive qualification.
