Lumex SML-LXIL0603 Series: Compact Narrow-Beam LEDs with an Established Quality Record

Lumex SML-LXIL0603 Series: Compact Narrow-Beam LEDs with an Established Quality Record

Focused Indication in a Compact Footprint

The SML-LXIL0603 series measures 1.64 x 0.84 x 1.15 mm and directs light through a focused 75-degree viewing angle. This combination supports a clear, defined visual signal for status, warning, and operating-state indication without increasing the PCB area allocated to the LED.

Its top-view construction directs the indication toward the face of the product, while the water-clear lens supports distinct color visibility and a clean appearance in compact interfaces, control panels, instruments, and portable equipment.

Product Highlights

Key details from the SML-LXIL0603 series

Compact package: 1.64 x 0.84 x 1.15 mm top-view surface-mount format.

Focused output: 75-degree viewing angle for front-directed indication.

Four emitted colors: Red, yellow, green, and blue.

Common platform: Package dimensions and recommended solder-pad layout are consistent across the series.

Current rating: Maximum continuous forward-current rating of 25 mA.

Operating range: -40 to +85 degrees C.

Supply format: 3,000-piece tape-and-reel packaging for automated placement.

Handling: Moisture Sensitivity Level 2 classification.

Compliance: RoHS compliant, EU REACH compliant, and halogen-free per the product datasheets.

Quality record: More than five years of market history with no customer complaints recorded by Lumex.

Four Colors in One Consistent Package

The series provides four common indication colors within the same mechanical platform. This supports consistent PCB layouts across product variants and allows different status functions to be implemented without introducing a separate package format for each color.

Part number Color Peak wavelength Typical intensity Typical forward voltage
SML-LXIL0603SIC-TR Red 630 nm 1,600 mcd 2.1 V
SML-LXIL0603SYC-TR Yellow 585 nm 1,350 mcd 2.1 V
SML-LXIL0603UPGCTR Green 520 nm 2,135 mcd 3.0 V
SML-LXIL0603USBCTR Blue 470 nm 500 mcd 3.0 V

Values are specified at IF = 20 mA and TA = 25 degrees C. Refer to the individual product datasheet for maximum ratings and complete design information.

Designed for Efficient Surface-Mount Assembly

All four versions share the same package dimensions and recommended solder-pad layout, supporting consistent board designs across color variants. The products are supplied in 3,000-piece tape-and-reel packaging for automated pick-and-place assembly, and each datasheet includes a recommended reflow-soldering profile.

The series is classified as Moisture Sensitivity Level 2 and is specified for operation from -40 to +85 degrees C. The supplied datasheets also identify the products as RoHS compliant, EU REACH compliant, and halogen-free, supporting common environmental compliance requirements for electronic component selection.

More Than Five Years of Complaint-Free Customer Performance

Component quality is demonstrated over time. Since the SML-LXIL0603 series was launched more than five years ago, Lumex has not recorded a customer complaint for the family. This complaint-free history provides a practical quality reference for a mature product series and supports confidence when the parts are considered for new or ongoing programs.

Combined with a stable mechanical platform, established color options, and assembly-ready packaging, the series offers more than a compact optical solution - it provides a component family with a documented record in the market.

Applications

The SML-LXIL0603 series is well suited to compact, front-facing indication in applications including:

Portable medical and diagnostic equipment
Industrial controls and instrumentation
Appliance interfaces and compact control panels
Telecommunications and network equipment
Security and access-control devices
Transportation and mobility-related electronics
Status indicators, controls, switches, and localized illumination

Final visibility should be confirmed using the intended drive current, viewing distance, ambient-light conditions, and finished enclosure or interface materials.

Bring Focused Indication to Your Next Design

The Lumex SML-LXIL0603 series combines a compact 0603-class footprint, focused 75-degree output, four color options, automated-assembly packaging, and an established complaint-free quality record. It remains a practical choice for products that need clear front-facing indication without consuming additional PCB space.
