Mounting and Soldering Recommendations:

Through-hole displays are not compatible with reflow soldering.
Mild "no-clean" fluxes are recommended for soldering.
Cleaning should be done with water only, avoiding harsh organic solvents.
Packing & Label Specifications:

The DC7G3HWA is packed and labeled according to Kingbright's standard procedures.
Circuit Design Notes:

Protective current-limiting resistors may be necessary for operating LEDs within the specified range.
LEDs mounted in parallel should each have their own current-limiting resistor.
The driving circuit should protect the LED against reverse voltages and transient voltage spikes.
Precautionary Notes:

The information provided is intended for technical reference and is subject to change without notice.
Customers should refer to the latest datasheet for updated specifications before production usage.
