TL4050B41IDCKR

Overview

The TL4050B41IDCKR 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 junction temperature range of -40°C to +125°C. The component is housed in a compact SC-70-5 surface-mount package, suitable for space-constrained designs requiring stable voltage regulation.

Feature Summary

• Delivers high-precision voltage regulation with tight initial accuracy tolerances
• Maintains stable performance across wide industrial temperature ranges
• Optimized for low power consumption through micropower shunt architecture

Applications

• Portable battery-powered instrumentation systems
• Handheld measurement devices requiring stable references
• Data acquisition systems needing precise analog front-ends

Procurement Notes

Verify the specific suffix IDCKR corresponds to the SC-70-5 package and tape-and-reel configuration. Confirm RoHS compliance status and ensure the ordering part number matches the required accuracy grade. Check for any recent product change notifications regarding packaging or material composition updates before finalizing procurement.

Selection Notes

Select this component when a fixed 4.096 V reference with ±0.2% accuracy is required in a small footprint. Consider the 50 ppm/°C temperature coefficient for thermal stability needs. Ensure the application can accommodate the SC-70-5 package dimensions and that the 15 mA maximum shunt current meets the circuit biasing requirements.

Part Context

This device belongs to the TL4050 family of precision shunt voltage references from Texas Instruments. It shares architectural similarities with other members like the TL4050A series but offers specific accuracy and noise characteristics defined by the 'B' grade. It serves as a compact alternative to larger package references in modern portable electronics.

Replacement Considerations

The TL4050B41IDCKRG4 is a verified lead-free variant of this component. Other family members such as the TL4050A41IDCKR offer different accuracy grades. Verify pinout compatibility and electrical specifications before substituting with LM4040 series devices.
