Procurement Notes

Verify the specific ordering suffix required for your manufacturing process. Confirm RoHS compliance status and lead-free plating requirements directly with the manufacturer or authorized distributor before placing orders. Ensure the component meets all environmental regulations applicable to your region.

Selection Notes

Select this component when a 5.6 V reference is needed with standard DO-41 through-hole mounting. Evaluate thermal management capabilities as power dissipation reaches 1.0 W at elevated ambient temperatures. Consider the temperature coefficient range of 0 to +0.045 %/°C for circuit stability requirements.
