This Product Selection Guide contains information to help select products in the Color LED Lighting category on DigiKey.com
Color LEDs used for illumination are characterized by fixed wavelength, wavelength range, and color group as well as 60 to 170 degree viewing angles. LEDS are available in surface mount packages such as SMD, CSDM, PLCC, J-lead, gull wing, exposed pad, and a wide variety of metric sizes as well as through-hole TO-252, DPak, SC-63, and radial lead configurations.
SelectionCharacteristics
Color: Indicates the color(s) of the LED(s).
Wavelength: Indicates the wavelength(s) of the light produced by the device.
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.
Voltage - Forward (Vf) (Typ): Characterizes the voltage drop across a forward-biased diode, measured at the test current indicated.
Lumens/Watt @ Current - Test: Characterizes a device’s luminous efficacy (light output per unit of electrical input power, compensated for typical human color sensitivity) measured at the indicated test current and a specified device test temperature.
Current - Max: This represents the maximum current to which a device will meet its given specifications. Exceeding this current may damage the device and/or other system components.
Luminous Flux @ Current/Temperature: Indicates the measurement of light energy emitted by a device operated at the listed test current and test temperature, which accounts for the varying sensitivity of the human eye to different wavelengths or colors.
Temperature - Test: Indicates the device temperature at which other listed device parameters are measured.
Viewing Angle: Indicates the angle of light emitted from the LED(s).
Mounting Type: Indicates how the device is attached.
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 physical dimensions of the device. Typically length X width.
Height - Seated (Max): Indicates how far the device will extend above the surface to which it has been attached.
