LED Indication - Discrete datasheet and documents for 521-8721F

521-8721F

LED Indication - Discrete Overview

The Dialight 521-8721F is a single-color orange LED lamp designed for through-hole mounting. It features a T-1 3/4 (5 mm) package with a diffused lens and dome shape. The component emits light at a wavelength of 605 nm with a viewing angle of 60 degrees. Electrical characteristics include a forward current of 20 mA, a forward voltage of 2.1 V, and a power rating of 100 mW. The optical intensity is specified as 90 mcd. It operates within a temperature range of -55 C to +100 C.

LED Indication - Discrete Feature Summary

Through-hole mounting style for standard PCB integration
Diffused lens design providing a 60-degree viewing angle
High operating temperature capability up to +100 C

LED Indication - Discrete Applications

Panel indicators
Machine status signaling
Control board visual feedback

LED Indication - Discrete Procurement Notes

Verify the specific datasheet revision and RoHS compliance status directly with the manufacturer or authorized distributor before finalizing procurement. Confirm that the Orange color specification matches the exact wavelength requirements of the application. Ensure the through-hole footprint aligns with the target PCB layout constraints.

LED Indication - Discrete Selection Notes

Select this component when a high-visibility orange indicator is required for general-purpose signaling. Consider the 60-degree viewing angle and diffused lens for broad visibility applications. Evaluate the +100 C maximum operating temperature against the environmental conditions of the intended installation site.
