Product Overview
The XL-304UYD from XINGLIGHT is a yellow through-hole LED built in an F3 long-lead package. The package dimensions are specified as 3.8 x 3.0 x 5.2 x 28 mm, with a yellow colloid body and yellow luminous output. Unless otherwise specified, outline dimensions carry a ±0.50 mm tolerance.
At Ta=25°C, the LED is rated for 70 mW power dissipation, 20 mA maximum continuous forward current, and 80 mA peak forward current. Electrical and optical values at IF=20 mA include 1.8 to 2.4 V forward voltage, 200 to 900 mcd luminous intensity, 585 to 595 nm dominant wavelength, 590 nm typical peak wavelength, 20 nm typical spectral half-width, and 30° typical viewing angle.
Assembly limits include 240°C reflow soldering for no more than 6 s and 300°C manual welding for 3 s, with the soldering point more than 2.0 mm from the colloid bottom. The part is specified for -20°C to +85°C operating ambient temperature and -40°C to +85°C storage ambient temperature.

Procurement Notes
When requesting a quote for XL-304UYD, buyers should confirm the manufacturer, package or case, required quantity, target date code, compliance documents, packing method, destination country and expected delivery schedule.
If alternatives are acceptable, buyers should share the approved vendor list, required electrical or optical limits, package constraints and qualification requirements. Any alternative part should be reviewed by the buyer's engineering team before production use.
For LED and optoelectronic sourcing, brightness bin, wavelength or color temperature bin, forward voltage range, viewing angle, moisture sensitivity level and soldering process limits may affect final selection, availability and lead time.

FAQ
What package is used for XL-304UYD?
XL-304UYD uses an F3 long-lead through-hole LED package. The extracted datasheet dimensions are 3.8 x 3.0 x 5.2 x 28 mm, with a general outline dimension tolerance of ±0.50 mm unless otherwise specified.
What are the main optical specifications at 20 mA?
At IF=20 mA and Ta=25°C, the LED has 200 mcd minimum, 500 mcd typical, and 900 mcd maximum luminous intensity. Dominant wavelength is 585 to 595 nm, peak wavelength is 590 nm typical, and viewing angle is 30 degrees typical.
What forward voltage range is specified for this LED?
At IF=20 mA and Ta=25°C, XL-304UYD is specified with 1.8 V minimum, 2.2 V typical, and 2.4 V maximum forward voltage. The datasheet measurement note gives forward voltage tolerance as ±0.1 V.
What soldering limits are listed in the datasheet?
The datasheet lists reflow soldering at 240°C for no more than 6 seconds and manual welding at 300°C for 3 seconds. In both cases, the soldering point must be more than 2.0 mm from the colloid bottom.
How is the packaging of XL-304UYD handled?
The XL-304UYD is packaged in moisture-proof and anti-electrostatic foil bags. As a through-hole device, it is supplied in bags rather than tape and reel. The datasheet specifies MSL 2 moisture sensitivity level for this part.
What is the typical application for the XL-304UYD?
The XL-304UYD is designed for general yellow visual indication in through-hole PCB designs. Common applications include panel status indicators, yellow signal lamps, equipment warning indicators, and control panel annunciators where through-hole assembly is preferred.
