LT QH9G-Q2S2-25-1

LED Indication - Discrete Overview

The LT QH9G-Q2S2-25-1 is a single-color True Green ChipLED manufactured by ams OSRAM. It utilizes a 0402 (1005 metric) surface-mount package with a rectangular lens measuring 1.2 mm x 0.9 mm. The component emits light at a peak wavelength of 530 nm and features a diffused lens for broad beam distribution. Key electrical parameters include a forward current of 5 mA, a forward voltage of 2.85 V, and a power rating of 14 mW. Optical performance specifications list an intensity of 270 mcd and a luminous flux of 1.09 lm.

LED Indication - Discrete Feature Summary

• True Green emission color optimized for high visibility applications
• Integrated diffused lens design for uniform light distribution
• Compact 0402 form factor suitable for space-constrained PCB layouts

LED Indication - Discrete Applications

• Status indicators in consumer electronics
• Instrument panel illumination
• Backlighting for small displays

LED Indication - Discrete Procurement Notes

Verify the specific ordering suffix against the manufacturer datasheet to ensure correct binning and optical characteristics. Confirm that the 0402 package dimensions align with the target PCB footprint. Check RoHS compliance status and lead times directly with authorized distributors prior to finalizing procurement plans.

LED Indication - Discrete Selection Notes

Select this component when a compact green indicator is required with moderate brightness levels. Ensure the driving circuit supports the specified 5 mA forward current limit. Consider the 2.85 V forward voltage drop when designing series resistor networks or constant current drivers for the application.

LED Indication - Discrete Part Context

This part belongs to the LT QH9G series of True Green ChipLEDs from ams OSRAM. The series is designed for general indication purposes where standard green LEDs may not provide sufficient visual impact. The 0402 package allows for high-density mounting on printed circuit boards compared to larger through-hole alternatives.

LED Indication - Discrete Replacement Considerations

Direct substitutes must match the 0402 package, 530 nm wavelength, and similar forward voltage characteristics. Verify compatibility with existing reflow soldering profiles and check if alternative suppliers offer equivalent luminous intensity ratings.
