TL4050B41QDCKT

Overview

The TL4050B41QDCKT is a precision micropower shunt voltage reference manufactured by Texas Instruments. It provides a fixed output voltage of 4.096 V with an initial accuracy of ±0.2%. The device features a temperature coefficient of 50 ppm/°C and supports a maximum cathode current of 15 mA. 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

• Delivers high-precision voltage regulation with tight initial tolerance specifications for accurate circuit referencing.
• Designed for low-power applications through micropower operation characteristics suitable for battery-powered systems.
• Engineered for automotive environments with AEC-Q100 qualification ensuring reliability under harsh conditions.

Applications

• Automotive sensor signal conditioning circuits
• Data acquisition systems requiring stable reference voltages
• Portable instrumentation with space constraints

Procurement Notes

Verify the specific suffix QDCKT against the official Texas Instruments datasheet to confirm package type, tape-and-reel configuration, and automotive grade status. Ensure compatibility with your PCB footprint and reflow soldering profile requirements before finalizing procurement orders.

Selection Notes

Select this component when a fixed 4.096 V reference with ±0.2% accuracy is required in a compact SC-70-5 package. Consider the 50 ppm/°C temperature coefficient for thermal stability needs and verify that the 15 mA load capability meets the downstream circuit demands.

Part Context

This part belongs to the TL4050 family of precision shunt voltage references from Texas Instruments. The family offers various fixed output voltages and accuracy grades, with the 'Q' designation indicating automotive qualification. The SC-70-5 package provides a small form factor ideal for dense board layouts.

Replacement Considerations

Check for TL4050B41IDCKT or other TL4050 variants with matching voltage and accuracy if automotive qualification is not strictly required. Verify pinout compatibility and thermal performance before substituting.
