## 2. Design Considerations
### Common Design Pitfalls and Solutions
Pitfall 1: Overcurrent Operation
- Problem : Driving LED beyond specified current limits
- Solution : Implement current-limiting resistors or constant current drivers
- Calculation Example : For 24V supply with 30mA target current: R = (24V - Vf) / 0.03A
Pitfall 2: Thermal Management Issues
- Problem : Inadequate heat dissipation leading to premature failure
- Solution : Ensure proper PCB copper pour and consider thermal vias for heat transfer
- Implementation : Minimum 2oz copper weight recommended for power traces
Pitfall 3: Reverse Polarity Damage
- Problem : Incorrect installation causing immediate failure
- Solution : Incorporate reverse polarity protection diodes in series
### Compatibility Issues with Other Components
Power Supply Compatibility:
- Requires stable DC power supply with minimal ripple
- Compatible with 12V, 24V, and 48V industrial standard voltages
- May require voltage regulation when used with switching power supplies
Microcontroller Interface:
- Direct drive possible with microcontroller GPIO pins (verify current sinking capability)
- For higher voltage systems, use transistor drivers or optocouplers
- PWM dimming compatible with appropriate drive circuitry
EMC Considerations:
- May generate electromagnetic interference during switching
- Requires proper filtering for sensitive analog circuits
- Maintain minimum 10mm separation from RF components
### PCB Layout Recommendations
General Layout Guidelines:
- Place indicator within 100mm of viewing surface
- Ensure unobstructed viewing path through enclosure
- Consider anti-glare treatments for high-ambient-light environments
Electrical Layout:
- Use star grounding for multiple indicators
