This Product Selection Guide contains information to help select products in the LED Indication - Discrete category on DigiKey.com
Light emitting diodes are semiconductor devices that emit light when conducting current. LEDs in this family are single or array configuration for status indication on printed circuit boards. They are differentiated by package/case, wavelength, viewing angle, forward voltage, current rating, millicandela rating, color, and mounting type. Configurations include common anode or cathode and bidirectional.
SelectionCharacteristics
Color: Indcicates the color emitted from the LED.
Configuration: Defines the internal arrangment of components.
Lens Color: Indicates the color of a device’s lens as it appears under incident ambient lighting. May differ from the color of light emitted by a device.
Lens Transparency: Describes the dispersion characteristics of a device’s lens.
Millicandela Rating: Characterizes device brightness at the indicated test current or nominal input voltage.
Lens Style: Characterizes the shape of a device’s optical emitting surface.
Lens Size: Defines the overall dimension of the bulb.
Voltage - Forward (Vf) (Typ): The rated working voltage of a device, given as a range or as a maximum.
Current - Test: Indicates the amount of current flow through a device used by a manufacturer as a test condition for characterization of one or more other device parameters.
Viewing Angle: Indicates the angle of light emitted from the LED(s).
Mounting Type: Indicates how the device is attached.
Wavelength - Dominant: The wavelength of a pure monochromatic light source that most closely matches the perceived color of the light emitted by a device.
Wavelength - Peak: Characterizes the highest point in a device’s output spectrum when operated at rated test conditions.
Features: Special performance and safety characteristics built into the part.
Package / Case: Indicates the type of protective case used on an electronic component to allow easy handling, installation, and protection.
Supplier Device Package: This is what the manufacturer calls the package of this device. They are manufacturer specific. It is typically best to use the actual dimensions from the datasheets rather than to go by this terminology when designing your circuit.
Size / Dimension: The overall length, and width of the part.
Height (Max): The overall height of the part.
