Glossary

1)

Brightness: Brightness values are measured during a pulse train of 100 ms with a pulse width of 250

µs and a frequencey of 1 kHz, with an internal reproducibility of +/‐ 8 % and an expanded uncertainty of

+/‐ 11 % (acc. to GUM with a coverage factor of k = 3). The peak brightness is calculated according to

the pulse duration and frequency.

2)

Reverse Operation: This product is intended to be operated applying a forward current within the

specified range. Applying any continuous reverse bias or forward bias below the voltage range of light

emission shall be avoided because it may cause migration which can change the electro-optical char-

acteristics or damage the LED.

3)

Wavelength: The wavelength is measured during a pulse train of 100 ms with a pulse width of 250 µs

and a frequencey of 1 kHz , with an internal reproducibility of ± 0,5 nm and an expanded uncertainty of

± 1 nm (acc. to GUM with a coverage factor of k=3).

4)

Typical Values: Due to the special conditions of the manufacturing processes of semiconductor devic-

es, the typical data or calculated correlations of technical parameters can only reflect statistical figures.

These do not necessarily correspond to the actual parameters of each single product, which could dif-

fer from the typical data and calculated correlations or the typical characteristic line. If requested, e.g.

because of technical improvements, these typ. data will be changed without any further notice.

5)

Forward Voltage: The forward voltage is measured during a pulse of typical 250 µs, with an internal

reproducibility of +/‐ 0,05 V and an expanded uncertainty of +/‐ 0,1 V (acc. to GUM with a coverage

factor of k=3).

6)

Characteristic curve: In the range where the line of the graph is broken, you must expect higher differ-

ences between single devices within one packing unit.

7)

Tolerance of Measure: Unless otherwise noted in drawing, tolerances are specified with ±0.1 and

dimensions are specified in mm.

8)

Tape and Reel: All dimensions and tolerances are specified acc. IEC 60286-3 and specified in mm.
