Potentiometers, or variable resistors, are a standard component that we take for granted. If it says “10k log” on a volume pot, than we fit and forget. But if like [Ben Holmes] you are modelling ...
The iC-HL 1,024-step logarithmic precision potentiometer is used to set the optical output power of laser diodes in conjunction with APC laser drivers. Across a wide resistance range of 350 Ω to 80 kΩ ...
