SC10-21SURKWA Hyper Red 1.0 Inch Single Digit Numeric Display
Descriptions
The SC10-21SURKWA numeric display utilizes 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 advised to use anti-static measures when handling the LEDs and ensure all equipment is electrically grounded.

Features
1.0 inch digit height for clear visibility.
Low current operation for energy efficiency.
Excellent character appearance and high light output.
Easy mounting on P.C. boards or sockets.
Mechanically rugged construction.
Standard gray face with white segment for high contrast.
RoHS compliant for environmental sustainability.
Applications
Home and smart appliances for numeric status indication.
Display time and digital combinations.
Industrial and instrumental applications requiring clear numeric display.
Attention
Handle with care to observe precautions for electrostatic discharge sensitive devices.

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.
