• Industrial control panels

LED Indication - Discrete Procurement Notes

Verify the specific suffix (e.g., TX, TXV) required for your application, as standard OVM4R variants may differ in screening levels. Confirm RoHS compliance status and lead times directly with the manufacturer or authorized distributors, as availability varies by process level. Ensure the selected part matches the required military screening specifications for your project.

LED Indication - Discrete Selection Notes

Select this component when hermetic sealing and high reliability are critical. Choose between TX and TXV suffixes based on the necessary screening levels defined by MIL-STD-750. Consider the 18-degree viewing angle and 630 nm wavelength for visibility requirements. Verify thermal management capabilities given the wide operating temperature range.
