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: Indicates the color(s) emitted from the LED.
Configuration: Indicates the internal electrical configuration 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: Indicates whether a device’s lens is designed to provide specular (clear) or diffuse optical transmission.
Millicandela Rating: Characterizes device brightness at the indicated test current or nominal input voltage.
Lens Style: Indicates the shape of the lens.
Lens Size: Indicates the physical dimensions of the lens.
Voltage - Forward (Vf) (Typ): This rating indicates the nominal amount of current you would expect the device to draw during normal operation, at the manufacturer defined test conditions
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: These are different capabilities or properties of the device such as List 2-3 examples
Package / Case: Indicates the type of protective case used on an electronic component to allow easy handling, installation, and protection. This selection was determined to be the closest industry standard applicable to the supplier device packaging. Typically it is best to check the actual dimensions from the datasheet rather than depend on this terminology when designing your circuit.
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.
