Overview
The B3843FCH-20C0001H2U1930 is a surface-mount RGB LED component manufactured by Harvatek Corporation. It features a common cathode configuration within a compact 4-SMD, no-lead package measuring 0.80mm in length and width, with a maximum height of 0.75mm. The device emits red light at a peak wavelength of 630nm, green light at 521nm, and blue light at 467nm. Typical forward voltages are specified as 1.9V for the red channel, and 2.5V for both the green and blue channels. The lens design is square with a flat top, providing a viewing angle of 140 degrees. Intensity ratings include 26mcd for red, 37mcd for green, and 7.5mcd for blue. The component is RoHS compliant and classified under ECCN EAR99.
Feature Summary
- Integrates red, green, and blue emitters into a single compact surface-mount package for unified color control.
- Features a square lens with a flat top design to optimize light distribution and visual appearance.
- Supports wide viewing angles of 140 degrees for broad visibility applications.
Applications
- Status indication in electronic devices requiring multi-color signaling
- Backlighting for small form-factor displays and user interfaces
- Decorative lighting modules in consumer electronics
Procurement Notes
Verify the specific ordering suffix against the manufacturer's current datasheet to ensure compatibility with required binning or packaging specifications. Confirm that the 4-SMD no-lead package dimensions align with the target PCB footprint. Check moisture sensitivity level (MSL 2A) requirements for reflow soldering profiles during assembly planning.
Selection Notes
Select this component when a low-profile RGB solution is required for space-constrained designs. The common cathode architecture simplifies driver circuitry compared to common anode variants. Ensure thermal management strategies account for the combined heat dissipation of three distinct LED chips within the small 0.80mm x 0.80mm footprint.
Part Context
This part belongs to the B3843 series of RGB LEDs from Harvatek Corporation. It shares the same physical package dimensions and general optical characteristics as other variants in the series but differs in electrical parameters such as forward voltage and intensity bins. It serves as a direct replacement for previous generations of similar-sized RGB components where specific wavelength or voltage tolerances are critical.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Verify cross-compatibility with existing PCB silkscreens and footprints if substituting with other Harvatek RGB models. Ensure that any alternative component matches the 4-SMD no-lead package style and 0.80mm x 0.80mm dimensions to maintain mechanical integrity.
