SC39-11SURKWA Hyper Red 0.39 Inch Single Digit Numeric Display
Descriptions
The SC39-11SURKWA numeric display features AlGaInP on GaAs substrate Light Emitting Diode technology, offering a hyper red color output. To prevent damage from electrostatic discharge and power surge, it is recommended to handle the LEDs with anti-static measures and ensure all equipment is electrically grounded.

Features
0.39 inch digit height for clear visibility.
Low current operation for energy efficiency.
Excellent character appearance.
Easy mounting on P.C. boards or sockets.
Mechanically rugged construction.
Standard gray face with white segment.
RoHS compliant for environmental sustainability.
Applications
Home and smart appliances for numeric status indication.
Display time and digital combinations.
Industrial and instrumental applications.

Soldering Profile and General Notes
Through-hole displays are incompatible with reflow soldering.
Mild "no-clean" fluxes are recommended for soldering.
Cleaning should be done with water only, avoiding harsh organic solvents.
Circuit Design Notes
Use protective current-limiting resistors for LED operation within the specified range.
Design the driving circuit to protect against reverse voltages and transient spikes.
Choose the safe operating current considering the maximum ambient temperature.
Precautionary Notes
Refer to the latest datasheet for updated specifications before production usage.
Operate the product within the environmental and electrical limits specified in the datasheet.
For special processes such as potting for LED assembly, consult with Kingbright representative.
