Kingbright SA56-11SURKWA Hyper Red Numeric Display

Product Overview:
The Kingbright SA56-11SURKWA numeric display utilizes Hyper Red Light Emitting Diodes (LEDs) made with AlGaInP on a GaAs substrate, offering superior brightness and visibility with low current operation. This display is designed for applications requiring clear and bright digital displays, with a focus on ESD protection and durability.

Key Features:

0.56-inch digit height for high visibility
Low current operation for energy efficiency
Excellent character appearance for easy readability
Simple mounting on PC boards or sockets
Mechanically rugged for reliability
Standard gray face with white segments for high contrast
RoHS compliant for environmental sustainability
Applications:

Home and smart appliances for status indication
Display time and digital combinations in clocks and timers
Industrial and instrumental applications requiring numeric status display
Handling Precautions:

Use wrist bands or anti-electrostatic gloves when handling LEDs.
Ensure all devices, equipment, and machinery are electrically grounded to prevent ESD damage.

Soldering and Cleaning Guidelines:

Through-hole displays are not compatible with reflow soldering.
Use mild "no-clean" fluxes for soldering.
For cleaning, use water only and avoid harsh organic solvents.
Clean at room temperature and limit wash time to one minute.
After washing with water, use forced-air drying to remove excess moisture promptly.
Mounting and Circuit Design Notes:

Avoid bending component leads by hand; use proper tools.
Ensure terminal pitch matches the substrate board's hole pitch.
Place components at least 5mm from the edge of the PCB to avoid damage from heat.
Design circuits with protective current-limiting resistors and consider reverse voltage protection.
Precautionary Notes:

Refer to the latest datasheet for updated specifications before production.
Operate products within the environmental and electrical limits specified.
For special processes like potting, consult with Kingbright representatives.
Regulatory Approvals:

This product is compliant with RoHS standards.
