Overview
The 11-21/Y2C-CR2S2B/3T is a single-color surface-mount LED manufactured by Everlight Electronics. It features a rectangular package with a water-clear lens and emits brilliant yellow light at a peak wavelength of 591 nm. The component has a total height of 0.8 mm and operates within a temperature range of -40 °C to 85 °C. It supports a maximum forward current of 0.025 A and provides a nominal luminous intensity of 20.0 mcd. The device is lead-free, RoHS compliant, and supplied in tape and reel packaging for automated placement.
Feature Summary
- Utilizes a compact 0.8 mm height SMD package to enable smaller board sizes and higher packing density.
- Compatible with automatic placement equipment and standard infrared or vapor phase reflow solder processes.
- Features a mono-color design with a water-clear lens for efficient light transmission.
Applications
- Indicator lights for electronic devices
- Panel illumination in consumer electronics
- Status indication in industrial control systems
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct binning and optical characteristics. Confirm that the requested quantity matches the factory pack size requirements. Check regional availability as distribution may vary. Ensure compliance with local environmental regulations regarding lead-free components. Validate the supplier's authorization status before purchase.
Selection Notes
Select this component when a low-profile yellow indicator is required for space-constrained designs. Consider the 0.8 mm height limit for strict vertical clearance specifications. Evaluate the 20.0 mcd intensity against visibility requirements for the intended application environment. Ensure the operating temperature range aligns with the system's thermal profile. Verify compatibility with existing reflow soldering profiles.
