Yellow mid-power indicator LED in the 3528 package (3.5 × 2.8 × 1.75mm). Delivers 400–600mcd at 20mA for reliable warning-state visibility in high-ambient industrial environments. Yellow at this output level maintains clear perceptual separation from adjacent red and green indicators even under strong ambient lighting — critical in three-state systems where color distinctiveness must be preserved at distance. Reflow solderable. Operating temperature −40°C to +85°C.
Detailed electrical and optical characteristics
At higher luminous intensity levels, bin variation is more perceptible. CMH's controlled production of the 3528 series holds the 400–600mcd output range tightly, maintaining the high-contrast visibility the application requires across all production batches and replacement orders.
Mid-power 3528 package. Confirm wavelength from CMH datasheet.
