Product Overview
The XL-0201UYC from XINGLIGHT is a high brightness yellow SMD LED supplied in an 0201 surface-mount package. The package dimensions are 0.65 x 0.35 x 0.4 mm, supporting compact board layouts where a small yellow indicator is required. The device uses transparent colloid and is specified as a high brightness yellow LED.
Electrical and optical characteristics are given at IF=20 mA and Ta=25°C. Luminous intensity is 80 to 180 mcd, dominant wavelength is 580 to 595 nm with 590 nm typical, peak wavelength is 590 nm typical, forward voltage is 1.7 to 2.3 V, half wave width is 20 nm typical, and viewing angle is 120° typical. Reverse current is specified as <=1 µA at VR=5 V.
Assembly guidance includes a maximum of two reflow soldering cycles and a recommended maximum welding temperature of 240 ±5°C for 6 s. For repair or rework, hand soldering is recommended with an iron below 30 W, temperature below 300°C, and less than 3 s per terminal.

Procurement Notes
When requesting a quote for XL-0201UYC, 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.
