Overview
The Citizen CL-340T-SD is a surface-mount RGB LED component with dimensions of 1.70mm x 1.40mm and a maximum height of 0.35mm. It features a rectangular lens with a flat top in a 6-SMD, no-lead package. The device emits red light at 618nm (1.85V forward voltage), green light at 530nm (2.7V forward voltage), and blue light at 470nm (2.75V forward voltage). Brightness levels are rated at 36mcd for red, 180mcd for green, and 40mcd for blue under a 5mA test current. This component is RoHS compliant and classified as obsolete.
Feature Summary
- Integrates red, green, and blue emitters into a single compact surface-mount package
- Features a rectangular lens design with a flat top profile
- Supports independent color configuration within a unified housing
Applications
- LED indicator applications requiring multi-color status display
- Discrete LED signaling in electronic assemblies
- Compact device illumination where space is limited
Procurement Notes
This component is officially listed as obsolete by the manufacturer. Verification of availability should focus on distributor inventory or alternative sourcing channels rather than direct manufacturing orders. Confirm end-of-life documentation details before integration planning to ensure supply chain continuity for existing designs.
Selection Notes
Designers must account for the specific forward voltage requirements of each color channel: 1.85V for red, 2.7V for green, and 2.75V for blue. The physical footprint measures 1.70mm by 1.40mm with a low profile of 0.35mm maximum height. Ensure circuitry supports the distinct wavelength outputs and brightness levels specified for each emitter within the single package.
Part Context
The CL-340T-SD belongs to the Citizen CL-340 series of surface-mount LEDs. This series provides integrated multi-color solutions in small form factors suitable for modern electronics. The component utilizes standard SMD mounting techniques and is designed for automated assembly processes common in consumer and industrial electronic manufacturing.
Replacement Considerations
As this part is marked obsolete, verify if any direct substitute part numbers are publicly confirmed by the manufacturer. No cross-references are provided in the source data.
