XL-524SURUBC is a red-blue bicolor through-hole LED in F5 package (diameter 5.9 mm, height 8.6 mm, lead length 28 mm). It features clear resin and a long-lead design for easy panel mounting or manual soldering, with a non-polar (bipolar) pin configuration that requires no polarity identification.
RoHS compliant with Moisture Sensitivity Level (MSL) 2. It offers low power consumption, long service life and high reliability, with a narrow 30° viewing angle (focused type).
Compared with the F3 version, the F5 package provides a larger emitting area and better heat dissipation, suitable for applications requiring larger light-emitting size or higher reliability.

Optical Characteristics
Red Chip
Dominant Wavelength (λd): 620~640 nm (typical peak: 630 nm)
Luminous Intensity (IV): 100~700 mcd (@20 mA, typical: 500 mcd, see datasheet for binning details)
Blue Chip
Dominant Wavelength (λd): 460~470 nm (typical peak: 465 nm)
Luminous Intensity (IV): 400~1200 mcd (@20 mA, typical: 1200 mcd, see datasheet for binning details)
Viewing Angle (2θ₁/₂): 30°
(Ultra-narrow angle with highly concentrated light output)
Electrical Parameters (Ta=25°C)
Red Chip
Maximum Power Dissipation: 50 mW
Maximum Continuous Forward Current: 20 mA
Forward Voltage: 1.8~2.4 V (@20 mA)
Blue Chip
Maximum Power Dissipation: 70 mW
Maximum Continuous Forward Current: 20 mA
Forward Voltage: 2.8~3.4 V (@20 mA)
Maximum Pulse Peak Forward Current (IFP): 80 mA (Pulse width ≤0.1 ms, Duty cycle ≤1/10)
Reverse Current (IR): ≤10 μA (VR=5 V)
ESD Withstand Capacity: <1000 V (Human Body Model, HBM); ≤100 V (Machine Model, MM). Its rating is lower than SMD LEDs, enhanced electrostatic protection is required during handling.
