Product Overview
XL-257SYGD-L is a XINGLIGHT yellow green through-hole LED with a 5.0 x 2.0 x 7.0 x 28 mm long-lead appearance dimension. The device has a green colloid color and yellow green luminous output, making it suitable for visual indication where this color point is required.
Electrical and optical characteristics are specified at IF=20 mA and Ta=25°C. The LED is rated for 50-100 mcd luminous intensity, 565-575 nm dominant wavelength, 570 nm typical peak wavelength, 15 nm typical spectral width at half height, and 110° typical viewing angle. Forward voltage is specified as 2.0-2.6 V with 2.2 V typical, and reverse current is limited to <=10 µA at VR=5 V.
Assembly limits include 240°C maximum reflow soldering for <=6 s and 300°C manual welding for 3 s, with the solder point more than 2.0 mm from the colloid bottom. The device is supplied in moisture proof and anti-electrostatic foil bags and carries MSL 2 classification.

Procurement Notes
When requesting a quote for XL-257SYGD-L, 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.
