Applications
The L-2914YD is commonly used as a status or warning indicator on control panels, industrial equipment front panels, and consumer electronics dashboards where a yellow visual signal is needed. Its through-hole radial package makes it suitable for prototype boards and applications requiring robust mechanical mounting. The diffused lens distributes light over a broad angle, making it effective in multi-LED bar-graph displays and alphanumeric indicator assemblies.

Frequently Asked Questions
What is the forward current limit of the L-2914YD, and how should a designer calculate the series resistor for a 5 V supply?
The L-2914YD has a maximum forward current of 30 mA. For a 5 V supply with a typical forward voltage of approximately 2.1 V, the required series resistor is (5 V − 2.1 V) / 0.02 A = 145 Ω when targeting a safe operating current of 20 mA. A standard 150 Ω resistor would keep the LED within its rated current while providing adequate brightness of roughly 13 mcd.
At what wavelength does the L-2914YD emit, and what viewing-angle benefit does the diffused lens provide?
The L-2914YD emits yellow light at a dominant wavelength of 588 nm, which sits squarely in the human eye's high-sensitivity yellow region. The diffused lens scatters the emitted photons over a wide angle, typically greater than 60° half-angle, making the LED visible from oblique directions without requiring the viewer to be directly in front of it. This is especially useful in panel-mount indicator rows where operators view displays from varying angles.
How does the rectangular package shape of the L-2914YD compare to a standard T-1 3/4 round LED for panel-mount cutout design?
The L-2914YD uses a rectangular lens body rather than a 5 mm round T-1 3/4 form factor. Rectangular LEDs allow tighter horizontal pitch in multi-LED arrays and can be snap-fitted into rectangular panel cutouts as small as 2 mm × 4 mm, whereas a T-1 3/4 round LED requires a 5 mm circular drill. This geometric difference lets designers pack more 13 mcd indicator points per unit length on a front-panel bezel.
Which industrial or consumer applications are best served by the L-2914YD's high-reliability rating?
The high-reliability rating of the L-2914YD makes it suitable for applications demanding low field failure rates over extended operational periods, such as industrial machine status panels, test-and-measurement equipment, and medical device indicators. At up to 30 mA continuous forward current, the LED can deliver consistent 588 nm yellow indication for thousands of hours in factory automation controllers, elevator floor indicators, and telecommunications rack-mount alarms.
