TL4050B41QDCKR

Overview

The TL4050B41QDCKR 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 shunt current of 15 mA. It operates within a temperature range of -40°C to +125°C and holds AEC-Q100 qualification for automotive applications. The component is housed in a compact SC-70-5 surface-mount package.

Feature Summary

• AEC-Q100 qualified for automotive reliability standards
• High precision with ±0.2% initial accuracy
• Micropower operation suitable for space-constrained designs

Applications

• Automotive data acquisition systems
• Portable instrumentation requiring stable references
• Battery-powered measurement devices

Procurement Notes

Verify the specific suffix 'Q' confirms AEC-Q100 automotive qualification and 'DCKR' denotes the SC-70-5 tape-and-reel packaging. Confirm the 'B' grade indicates the required ±0.2% accuracy tier. Ensure the 4.096V output matches the system design requirements before procurement.

Selection Notes

Select this part when automotive certification is mandatory alongside high precision. The SC-70-5 package offers a small footprint compared to larger alternatives. Consider the 15mA current limit for load driving capabilities and verify thermal management needs for the specified operating temperature range.

Part Context

This component belongs to the TL4050 family of precision shunt voltage references. The family includes various output voltages and accuracy grades. The 'Q' suffix specifically identifies automotive-grade versions that meet rigorous reliability standards, distinguishing them from standard commercial variants within the same product line.

Replacement Considerations

Check for TL4050B41IDCKR for commercial grade equivalents or TL4050B41QDBZR for SOT-23-3 package alternatives. Verify pinout compatibility and electrical parameter alignment before substitution.
