3YDL-F is listed in the LED Indication - Discrete range at ChipApex. The manufacturer field lists Bivar Inc.. Its product description is LED YELLOW DIFFUSED T-1 T/H. Review the specifications below when checking this part for your BOM.
The Bivar Inc. 3YDL-F is a single-color yellow LED designed for through-hole mounting in a T-1 (3 mm) package. It features a diffused lens with a domed top and emits light at a wavelength of 590 nm. The component has a typical forward voltage of 2 V and a luminous intensity of 2 mcd. It operates at a forward current of 2 mA with a power rating of 10 mW and offers a viewing angle of 35 degrees.
Verify the specific ordering suffix to confirm lens transparency and color specifications, as variations exist within the product line. Confirm RoHS compliance status directly from the manufacturer datasheet before integration. Ensure the through-hole footprint matches the T-1 package dimensions during layout design. Check current availability as discrete components may have limited stock or end-of-life status depending on the region.
Select this component when a standard 3mm yellow indicator is required for visual signaling. The diffused lens is suitable for applications needing broad visibility rather than focused beams. Verify that the 2V forward voltage aligns with the driving circuit capabilities. Consider the 2mA operating current for power budget calculations. Ensure the mechanical clearance accommodates the radial leads and dome height.
This part belongs to Bivar's discrete LED family, specifically the T-1 series. It serves as a visual feedback element in various electronic assemblies. The 3YDL-F variant specifies the yellow color and diffused lens characteristics. It is distinct from surface-mount or multi-color variants within the broader Bivar portfolio.
