Overview
The AA4040SEKJ3CGKCT10MA is a dual-color surface-mount LED by Kingbright, featuring red and green chips in a right-angle PLCC-2 package. It emits at 625nm (red) and 570nm (green). The device has a forward voltage of approximately 2V for both colors and operates at a standard forward current of 20mA. Dimensions are 4.0mm x 4.0mm with a height of 4mm. It utilizes a water-clear lens with a dome shape and offers a viewing angle of 90 degrees. The component is rated for operation between -40°C and +85°C.
Feature Summary
- Dual-color configuration combining red and green emission within a single compact package
- Right-angle lead design facilitates vertical mounting on printed circuit boards
- Water-clear dome lens provides consistent light transmission and visibility
Applications
- Status indication on electronic control panels
- Indicator lights for consumer appliances
- Visual signaling in compact instrumentation devices
Procurement Notes
Verify the specific suffix 'J3CGKCT10MA' against the manufacturer's official datasheet to confirm pinout orientation and binning specifications. Ensure compatibility with automated pick-and-place equipment due to the right-angle form factor. Confirm RoHS compliance status through the latest production documentation before finalizing supply chain agreements.
Selection Notes
Select this component when space constraints require a dual-color indicator in a standard PLCC-2 footprint. The right-angle orientation is suitable for applications requiring LEDs to face upward from a horizontal board. Verify that the required forward current and voltage levels align with the driving circuit design to ensure optimal brightness and longevity without exceeding thermal limits.
Part Context
This part belongs to Kingbright's AA series of surface-mount LEDs, designed for high-density PCB layouts. The 4040 package size is widely used in modern electronics where minimal profile and reliable performance are critical. The dual-color capability allows for distinct visual states using a single component location.
Replacement Considerations
Direct substitutes include other Kingbright AA4040 series dual-color LEDs with matching right-angle configurations. Verify electrical parameters such as forward voltage and luminous intensity to ensure functional equivalence. Alternative packages may require mechanical redesign of the host device.
