APT1608SURCK
Overview
The APT1608SURCK is a high-brightness Hyper Red LED in a standard 0603 surface-mount package. Utilizing AlGaInP on GaAs substrate technology, it provides a luminous intensity of 80mcd at a 20mA test current with a wide 120-degree viewing angle. Its 1.6mm x 0.8mm footprint and low 0.75mm profile make it ideal for compact status indication in space-constrained designs.
Why Choose This Part
This LED features a low typical forward voltage of 1.95V, allowing for efficient operation from 3.3V or 5V rails with standard current-limiting resistors. The 120-degree viewing angle ensures consistent visibility from various perspectives, while the clear lens maximizes light output for a bright 80mcd rating.
Applications
Key Specifications
Getting Started
Ensure a current-limiting resistor is placed in series with the LED to target the 20mA nominal operating current; for a 3.3V supply, a 68-ohm resistor is recommended. Follow standard SMD reflow profiles, noting the package height of 0.75mm to ensure proper solder paste stencil thickness and pick-and-place nozzle selection.
