PIB LED, wave length 870 nm

For determining Planck's constant “h” with LEDs (internal photoelectric effect);
Plug-in module for NTL student experiments (STB), LED, wavelength 870 nm, infrared;
robust plastic housing with transparent base plate, the component is therefore clearly visible and also protected against mechanical damage, the base plate is screwed on with Phillips screws, broken components can therefore be repaired or replaced very quickly and easily, screen-printed lines and circuit symbols create a clearly recognizable circuit diagram of an experimental set-up, robust 4 mm plug pins enable a secure electrical plug-in connection with the metal plates of the plug-in plate
Base plate with two plug pins
Distance between the plug pins: 19 mm
Type: Light-emitting diode, wavelength 875 nm, infrared
Diameter: 5 mm
Blocking voltage: 5 V
Forward current: 100 mA (200 mA peak)
Power loss: 180 mW
RoHS compliant
Material (upper part): ABS plastic, yellow
Material (plug pins): Brass, nickel-plated
Dimensions: 40 x 40 x 27(45) mm
Mass: 22 g

To carry out the experiment, additional LEDs with other wavelengths and the plug-in module for current limitation are required, but it is better to use the entire P9901-PK Planck device set “STB”.
