CL-270YG-C

Overview

The Citizen CL-270YG-C is a surface-mount yellow-green LED with a dominant wavelength of 575nm. It features a typical forward voltage of 2.2V at a test current of 20mA. The component utilizes a 2-SMD, no-lead package with a rectangular lens measuring 1.20mm x 0.60mm and a flat top style. Designed for right-angle mounting, it offers high-density integration capabilities suitable for compact electronic assemblies requiring discrete indication.

Feature Summary

• Compact surface-mount design with right-angle orientation for space-constrained applications
• Yellow-green emission with dominant wavelength of 575nm
• Low power consumption characteristics with standard 20mA test current operation

Applications

• Indicator lights in portable consumer electronics
• Status indication on medical devices
• Control panel signaling in industrial equipment

Procurement Notes

Verify the specific suffix (e.g., -TS) required for tape-and-reel packaging if automated assembly is intended. Confirm that the base part number corresponds to the correct luminous intensity grade and binning requirements for your optical design. Ensure compatibility with reflow soldering profiles specified in the official datasheet to maintain junction integrity during manufacturing processes.

Selection Notes

Select this component when a small form factor with right-angle light emission is necessary. Consider the 575nm wavelength for visibility requirements in ambient lighting conditions. Evaluate the 2.2V forward voltage drop against your circuit's supply rails to ensure proper current limiting resistor calculation. Verify mechanical clearance for the 1.20mm x 0.60mm footprint in the PCB layout.

Part Context

This part belongs to the Citizen CL-270 series, which focuses on ultra-small SMD LEDs. The series provides various color options and lens styles within a standardized miniature footprint. The CL-270YG-C specifically addresses the need for yellow-green indication in high-density mounting scenarios where board space is limited but reliable visual feedback is critical.

Replacement Considerations

Consult official substitution guides for equivalent components from other manufacturers offering similar 2-SMD no-lead packages. Verify dimensional tolerances and spectral output matches before replacing. Cross-reference pinout configurations if alternative suppliers offer different lead arrangements despite identical package codes.
