Key Features
- Yellowish-green emission with milky white diffused lens producing 40 mcd at 20 mA for uniform indicator lighting
- 20 mA maximum forward current in a compact SMD package suitable for high-density PCB indicator arrays
- Single LED configuration with JESD-609 e4 code for lead-free RoHS-compliant reflow soldering assembly
Applications
SML-D12M1WT86 is well-suited for status indicator arrays on industrial control panels, consumer electronics front panels, and embedded system boards where compact yellowish-green SMD LEDs with diffused milky white lenses are needed. Its 40 mcd brightness at 20 mA forward current provides clear visual status indication in moderate ambient light environments, such as networking equipment and appliance control displays. The surface-mount form factor supports automated assembly in LED indicator rows on PCBs for power supply modules, audio equipment, and medical device status displays.

Frequently Asked Questions
What color and luminous intensity does SML-D12M1WT86 produce at rated current?
SML-D12M1WT86 emits yellowish-green light with a typical luminous intensity of 40 mcd at its nominal operating current. The milky white diffused lens provides wide-angle light distribution suitable for status indicator panels visible from viewing angles up to 120 degrees in consumer and industrial electronics.
What is the maximum forward current rating for SML-D12M1WT86 and how should it be driven in indicator circuits?
The maximum forward current for SML-D12M1WT86 is 20 mA. For safe operation, a current-limiting resistor should be selected based on supply voltage; for a 3.3 V rail with approximately 2.1 V forward voltage, a 60 Ω resistor limits current to about 20 mA, while a 100 Ω resistor provides a safer 12 mA drive level for extended component lifetime.
In which SMD package is SML-D12M1WT86 housed and how does it benefit high-density PCB designs?
SML-D12M1WT86 is packaged in a small surface-mount form factor compatible with automated pick-and-place assembly. The compact SMD footprint enables indicator LED arrays with 2 mm or tighter center spacing on PCBs, allowing 10 or more status LEDs per centimeter of board length in front-panel indicator strips for networking switches and industrial PLCs.
How does the milky white diffused lens of SML-D12M1WT86 compare to a clear-lens LED for panel indicator use?
The milky white diffused lens of SML-D12M1WT86 scatters light over a wider viewing angle than a clear-lens LED, typically expanding the half-intensity viewing angle from around 30° for clear-lens types to 60° or more. This makes SML-D12M1WT86 more readable from off-axis viewing positions in equipment panels, reducing the viewing angle sensitivity that clear-lens 40 mcd LEDs exhibit in operator interface applications.
