Overview
The 12-21C/W1D-AR1S2/2C is a white surface-mount LED manufactured by Everlight Electronics. It features a right-angle lens design and operates at a forward voltage of 3.3V. The component utilizes InGaN material technology to produce cool white light with a water-clear resin lens. Designed for SMT installation, it supports infrared reflow soldering processes. The device offers a wide viewing angle and low power consumption, making it suitable for compact electronic applications requiring efficient illumination.
Feature Summary
- Right-angle lens configuration for directional light emission
- Low power consumption characteristics
- Wide viewing angle capability
Applications
- Light guide applications
- Decorative lighting
- Entertainment lighting
- Indicator illumination
Procurement Notes
Verify the specific ordering suffixes against the manufacturer's official documentation to ensure correct lens orientation and packaging specifications. Confirm RoHS compliance status and moisture sensitivity levels prior to assembly. Cross-reference the part number with the latest Everlight datasheet to validate current manufacturing availability and any potential product change notifications affecting this specific variant.
Selection Notes
Select this component when a right-angle light output is required for space-constrained designs. The 3.3V forward voltage rating must align with the system's drive circuitry. Ensure the PCB layout accommodates the specific SMD footprint dimensions. Consider the wide viewing angle for uniformity requirements in decorative or indicator applications where direct line-of-sight is not strictly necessary.
Part Context
This part belongs to Everlight's discrete single-color LED portfolio, specifically engineered for surface-mount technology. It represents the company's focus on compact, high-efficiency optical components. The right-angle design distinguishes it from standard top-view LEDs, offering flexibility in optical path routing within tight mechanical enclosures for consumer electronics and lighting modules.
Replacement Considerations
Consult Everlight's official substitution guide for verified alternatives. Generic replacements may differ in luminous intensity, viewing angle, or thermal characteristics. Verify pin compatibility and spectral consistency before integrating substitute parts into existing designs.
