📌 Product Overview
The XL-504RGBC is a standard 5mm radial LED designed for full-color illumination in channel letters and indicator panels. It utilizes a transparent epoxy colloid to maximize light output for Red, Green, and Blue chips.
💡 Engineering focus should prioritize thermal management and forward voltage matching due to the varying Vf requirements across the three internal diodes. While compliant with RoHS standards, the device requires strict adherence to moisture sensitivity level (MSL) 2 protocols to prevent popcorning during reflow soldering.
🔦 Typical Applications
Based on the optical parameters (1300 mcd for Green, 700 mcd for Blue, 600 mcd for Red) and the 5mm form factor, the XL-504RGBC is suited for:
- ✅ Channel Lettering & Signage: High-intensity output ensures visibility in outdoor advertising light boxes.
- ✅ Electronic Indicator Lights: Suitable for industrial control panels and status identification.
- ✅ Decorative Lighting: Used in arts, crafts, and special clothing requiring flexible, point-source RGB lighting.
- ✅ ** backlighting:** Effective for small-scale illumination and pilot lights.
⚡ Key Technical Specifications
The optical performance varies significantly by color chip, requiring specific drive calculations for uniformity.
| Parameter | Symbol | Red (Typ) | Green (Typ) | Blue (Typ) | Unit |
|---|---|---|---|---|---|
| Dominant Wavelength | $\lambda_d$ | 620–625 | 515–530 | 460–475 | nm |
| Light Intensity | $I_V$ | 600 | 1300 | 700 | mcd |
| Forward Voltage | $V_F$ | - | - | 2.0 – 5.0 | V |
| Half-Value Angle | $2\theta_{1/2}$ | - | - | 120 | Deg |
| Flash Frequency | $FREQ$ | - | 1.07 ± 30% | - | Hz |
Note: Intensity ($I_V$) is measured at $I_F=20mA$. The wide forward voltage range (2.0–5.0V) implies the need for individual current limiting resistors per color channel.
⚠️ Absolute Maximum Ratings & Process Limits
Exceeding these parameters risks irreversible damage to the LED chip or epoxy encapsulation.
| Parameter | Symbol | Max Rating | Unit | Conditions |
|---|---|---|---|---|
| Max Power Dissipation | $P_M$ | 200 | mW | $T_a=25^\circ C$ |
| Max Continuous Forward Current | $I_F$ | 40 | mA | DC operation |
| Peak Forward Current | $I_{FP}$ | 100 | mA | Pulse width dependent |
| Reverse Voltage | $V_{RM}$ | 5 | V | - |
| Operating Temperature | $T_{OPR}$ | -20 ~ +85 | $^\circ C$ | - |
| Storage Temperature | $T_{STR}$ | -40 ~ +85 | $^\circ C$ | - |
| Soldering (Reflow) | $T_{sol}$ | 240 | $^\circ C$ | $\le 6s$ |
🚨 Critical Warning: Soldering joints must be >2.0mm from the colloid bottom. Manual welding must not exceed 300°C for 3 seconds.
📦 Package, Dimensions & Assembly Notes
- Model: F5/5.95.08.6*29mm
- Tolerance: ±0.50mm (unless noted)
- MSL: Level 2 (Floor life: 1 year at <30°C / 60% RH)
Assembly Guidelines:
- Lead Forming: Bending must occur at least 2mm away from the epoxy body to prevent mechanical stress on the die bond.
- Cleaning: Avoid chemicals containing Trichloroethylene or Acetone. Use Ethanol for <3 minutes at room temperature.
- ESD: Standard anti-static precautions are required during handling.
🚢 Sourcing & Supply Considerations
- Packaging: Supplied in moisture-proof and anti-electrostatic foil bags (EIA standard).
- Consistency: Verify chromaticity binning if large batches are required for uniform signage lighting.
- Authenticity: Confirm supply chain channels to avoid off-spec components that do not meet the 120-degree viewing angle or luminous intensity specs.
- Lead Time: Check availability for high-volume orders involving channel letter applications.
❓ Frequently Asked Questions
Q: What is the forward voltage requirement for the XL-504RGBC?
A: The datasheet lists a broad range of 2.0V to 5.0V. Designers must treat the Red, Green, and Blue diodes as separate loads. Red typically sits near the lower end (2.0V), while Green and Blue may require higher voltages (3.0V+) at 20mA.
Q: Can this LED be reflow soldered?
A: Yes, it supports reflow soldering at 240°C for ≤6 seconds. However, it is classified as Moisture Sensitivity Level (MSL) 2. It must be baked according to J-STD-033 if the moisture-proof bag has been breached and storage time exceeded 72 hours.
Q: What is the viewing angle of this component?
A: The XL-504RGBC features a 120-degree half-light angle. This wide dispersion makes it suitable for backlighting and channel letters where diffuse light is preferred over a focused spot.
Q: How should I handle the leads during assembly?
A: You must use fixtures or professional tools for lead forming. Ensure any bends are at least 2mm away from the colloid bottom. Do not apply mechanical stress to the base after soldering to the PCB.
