LED SMD 3528 amber 180–320 mcd 120° indicator light

SMD 3528 amber LED with a luminous intensity of 180–320 mcd and a 120° viewing angle designed for surface-mount applications. This compact indicator light provides stable amber color output with low power consumption, suitable for PCB-mounted indicators, instrument panel markers, signage accents and low-power backlighting. Its standardized 3528 package allows reflow soldering and automated placement for mass production and quick repair tasks.

Advantages

The LED delivers consistent amber illumination within the specified intensity range, ensuring predictable visual performance across assemblies. Its wide 120° viewing angle offers good off-axis visibility for indicators and status signals. Low power draw reduces thermal load on small PCBs, while the SMD package supports automated pick-and-place and reflow soldering workflows. Stable color rendering and compact size simplify integration into tight layouts and enclosure designs.

Suitable for

• PCB indicator lights and status LEDs
• Instrument panel and control board markers

How to use

Integrate the LED on the PCB footprint designed for the 3528 SMD package, following standard pad dimensions and solder mask recommendations. Drive the diode with an appropriate current-limiting resistor or constant-current source to maintain luminous intensity within the 180–320 mcd range; refer to your circuit’s voltage and current parameters when selecting resistor values. Use standard reflow soldering profiles compatible with SMD components and avoid prolonged exposure to excessive peak temperatures. During assembly, ensure correct polarity alignment and check solder joints for proper wetting.

Usage recommendations

For long-term reliability, operate the LED within its recommended current range and maintain adequate PCB thermal management. When placing multiple LEDs, allow for slight spacing to prevent thermal accumulation and preserve color consistency. When used in visible indicators, verify mounting orientation and viewing angle in the final assembly to ensure the 120° beam covers the intended observation area.
