Detailed Description

A 1 Digit 7 Segment Display, also known as a Single Digit Seven Segment Display, is an LED component used to display one numeric character from 0 to 9. Its seven individually controlled illuminated segments form clear numeric characters that can be read quickly in electronic and industrial environments.

These displays are widely selected for applications requiring a simple, direct and dependable numeric indication. They can display an individual measurement, setting, position, count, level, channel number or equipment status.

Alfa Electronic Components offers 35 Single Digit Seven Segment Display variants across multiple digit heights, body dimensions, pin positions, decimal-point arrangements and polarity options. Buyers can review the product grid and reference datasheets to identify the configuration best suited to their circuit, PCB layout and visibility requirements.

Complete Size Range

The available digit heights cover:

  • Compact sizes: 0.3″, 0.32″, 0.36″, 0.39″ and 0.56″
  • Medium sizes: 0.8″, 1.0″, 1.2″, 1.5″ and 1.8″
  • Large sizes: 2.3″, 3.0″, 4.0″ and 5.0″

Compact displays are generally selected where PCB space is limited. Medium-sized displays offer balanced visibility for instruments and control panels, while larger displays are useful when readings must be visible from farther away.

Common Anode and Common Cathode Options

The range includes both Common Anode (CA) and Common Cathode (CC) configurations. The required polarity must correspond with the display driver and circuit design. Buyers should confirm this specification before ordering because the two configurations cannot always be used interchangeably.

Pin and Mounting Configurations

Depending on the selected model, the display may feature:

  • Side Pin configuration
  • Up/Down Pin configuration
  • Selected compact variants with 2 mm pin pitch
  • Multiple body dimensions within the same digit height

Digit height alone does not determine PCB compatibility. Body size, pin direction, pin pitch and pin arrangement must also be checked carefully.

Decimal-Point Options

Most variants include a right decimal point (RDP). Selected models provide both right and left decimal points (RDP and LDP), while a larger-format option includes a comma and right decimal point.

These arrangements support different numeric formats used in measuring instruments, counters and display assemblies.

Key Features

  • Clear single-digit numeric indication from 0 to 9
  • Consolidated selection of 35 variants
  • Fourteen digit heights from 0.3" to 5.0"
  • Common Anode and Common Cathode availability
  • Side Pin and Up/Down Pin configurations
  • Right and left decimal-point options on selected models
  • Comma configuration available in a selected large-size variant
  • Multiple body dimensions for different PCB layouts
  • Compact 2 mm pitch option available
  • HP-type 0.56" option available
  • Suitable for PCB-mounted electronic assemblies
  • Individual model reference datasheets
  • Suitable for prototype, regular production and bulk requirements

Selection Guidance for Buyers

Consider the following parameters before selecting a variant:

  • 1. Digit height and viewing distance

    Select a compact digit for space-constrained products and a larger digit where readings need to be viewed from a greater distance.

  • 2. Body dimensions

    Models with the same digit height may have different body dimensions. Check the complete length, width and depth against the available enclosure and PCB space.

  • 3. Polarity

    Confirm whether your driver circuit requires a Common Anode or Common Cathode display.

  • 4. Pin position and pitch

    Check whether the PCB requires Side Pins or Up/Down Pins. For compact designs, verify the exact pin pitch and arrangement.

  • 5. Decimal-point format

    Choose between RDP, RDP and LDP, or the selected comma configuration according to the numeric format required.

  • 6. Model and datasheet verification

    Confirm the exact model number and latest approved technical drawing before finalising component placement or production quantities.
