Overview
The Everlight 12-21C/Y2C-AP1Q2L/2C is a single-color surface-mount LED designed for indicator applications. It features a rectangular chip package with a total height of 0.8 mm and utilizes a water-clear lens. The component emits brilliant yellow light with a peak wavelength ranging from 585.5 nm to 594.5 nm. It operates with a maximum forward current of 20 mA and delivers a nominal luminous intensity of 78.5 mcd. The device is lead-free, RoHS compliant, and compatible with standard infrared and vapor phase reflow soldering processes.
Feature Summary
- Compact 0.8 mm height rectangular SMD package enables higher board density and reduced storage space.
- Brilliant yellow emission with water-clear lens provides high visibility for status indication.
- Compatible with automatic placement equipment and standard reflow soldering profiles.
Applications
- Status indicators on electronic circuit boards
- Panel-mounted visual signaling devices
- Consumer electronics status lights
Procurement Notes
Verify the specific binning codes for luminous intensity and wavelength when ordering, as these parameters can vary within the specified ranges. Confirm that the procurement channel is an authorized distributor to ensure component authenticity and traceability. Check for any regional shipping restrictions or supply limitations associated with this specific part number before finalizing purchase orders.
Selection Notes
Select this component when a low-profile yellow indicator is required for space-constrained designs. Ensure the driving circuit supports the 20 mA forward current specification. Verify that the operating temperature range of -40 °C to 85 °C aligns with the environmental conditions of the target application. Consider the rectangular shape factor for PCB layout optimization compared to circular packages.
Part Context
This part belongs to Everlight's 12-21 series of surface-mount LEDs, which are characterized by their compact dimensions and suitability for automated assembly. The series offers various color options and lens types to meet diverse industrial and consumer lighting requirements. The 12-21C variant specifically denotes the rectangular form factor with a 0.8 mm height, distinguishing it from other package styles in the broader product line.
Replacement Considerations
Direct substitutes may include other 0603-sized yellow SMD LEDs from manufacturers such as Kingbright or Osram, provided they match the pin configuration, forward voltage, and mechanical dimensions. Always verify electrical characteristics and thermal performance against the original datasheet before swapping components.
