Overview
The Citizen CL-421-C4-SD-TS is a discrete RGB LED indicator featuring Red, Green, and Blue emitters in a 4-SMD no-lead package. The red emitter operates at 624nm with a forward voltage of 2.2V. The green emitter operates at 530nm with a forward voltage of 3.45V. The blue emitter operates at 470nm with a forward voltage of 3.2V. The component supports an operating temperature range from -25°C to +80°C.
Feature Summary
- Integrates red, green, and blue light sources within a single compact surface-mount device.
- Utilizes a lead-free 4-SMD package design for automated assembly compatibility.
Applications
- Status indication on electronic circuit boards
- Multi-color signaling in consumer devices
- Visual feedback systems in industrial equipment
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct wavelength and electrical characteristics. Confirm that the 4-SMD no-lead package matches your PCB footprint requirements. Check for any recent updates to the datasheet regarding thermal or electrical ratings before finalizing procurement.
Selection Notes
Select this component when a compact RGB solution is required for space-constrained designs. Ensure the driving circuitry can accommodate the distinct forward voltages of the red (2.2V), green (3.45V), and blue (3.2V) channels. Verify that the operating temperature range meets the environmental conditions of the target application.
Part Context
This part belongs to the Citizen CL-421 series of discrete LEDs. It is designed for surface-mount technology applications requiring multi-color output in a small form factor. The series is intended for use in devices where visual status indication is critical.
Replacement Considerations
Consult official substitution guides for compatible RGB SMD LEDs. Verify pinout compatibility and forward voltage tolerances if considering alternative manufacturers. No specific substitute part numbers are confirmed in the provided data.
