IN-S121DASRYG

LED Indication - Discrete Overview

The IN-S121DASRYG is a dual-color surface-mount LED from Inolux, featuring red and yellow-green emission in a 3210 package. It utilizes a common anode configuration with a clear, domed rectangular lens. The device operates at a typical forward voltage of 2.2V for the red diode and 2.6V for the yellow-green diode. Peak wavelengths are specified at 622nm for red and 573nm for yellow-green. Luminous intensity reaches 110mcd for red and 30mcd for yellow-green at a test current of 20mA. The component supports an operating temperature range of -30°C to +85°C.

LED Indication - Discrete Procurement Notes

Verify the specific package dimensions against PCB layout requirements, as datasheets may list conflicting size specifications. Confirm the forward voltage ratings match the driving circuit capabilities to ensure proper operation. Check moisture sensitivity level handling procedures during assembly to prevent damage. Ensure the common anode polarity aligns with the schematic design before finalizing procurement orders.

LED Indication - Discrete Selection Notes

Select this component when a compact dual-color indicator is required for space-constrained designs. The common anode setup reduces pin count compared to independent cathode configurations. Consider the luminous intensity requirements, noting the lower output of the yellow-green element. Verify thermal management needs given the specified operating temperature range for the intended environment.
