TL4050C50IDCKR

Overview

The TL4050C50IDCKR is a precision micropower shunt voltage reference manufactured by Texas Instruments. It provides a fixed output voltage of 5 V with an initial accuracy of 0.5%. 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 is housed in a compact SC-70-5 surface-mount package.

Feature Summary

• Provides stable 5 V reference output with 0.5% initial accuracy
• Operates over extended industrial temperature range up to 125°C
• Compact SC-70-5 surface-mount package for space-constrained designs

Applications

• Portable instrumentation requiring precise voltage references
• Battery-powered measurement systems
• Data acquisition channels needing stable reference voltages

Procurement Notes

Verify the specific suffix IDCKR corresponds to the SC-70-5 package and standard commercial grade specifications. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets before integration into production designs.

Selection Notes

Select this component when a 5 V shunt reference with 0.5% accuracy is required in a small footprint. Consider the 50 PPM/C temperature coefficient for thermal stability needs. Ensure the design accommodates the 15 mA maximum shunt current capability for proper biasing.
