Specification Notes
(These notes are referenced on the following LED Vactrol Data Sheet pages.)
1
Since the input has a substantially constant voltage drop, a current limiting resistance is required.
Dark adapted resistance measured after 24 or more hours of no input.
2
3
4
Measured 10 sec. after removal of the input. The ultimate resistance is many times greater than the value at 10 seconds.
Ascent measured to 63% of final conductance from the application of 40 mA input. The conductance rise time to a specified value is
increased at reduced input drive while the conductance decay time to a specified value is decreased.
5
Typical matching and tracking from 0.4 to 40 mA is 25%.
6
Measured 5 sec. after removal of the input. The ultimate resistance is many times greater than the value at 5 seconds.
7
VTL5C9 response times are based on a 2.0 mA input. VTL5C10 response times are based on a 10.0 mA input for ascent time and
a 1.0 mA input for decay time.
