Datasheet

Linearity Tolerance is 4% over the Nominal Resistance range of 1K0 to 1M0. The Linearity
Tolerance is measured on at least 70% of the effective rotation range.
Note. In the case of Terminal and Zero-based linearity, both present constraints which
increase the manufacturing difficulty and in consequence have an adverse effect on the
product's price and availability.
Potentiometer linearity
Matching Tolerance (For Tandem Stereo Potentiometers)
Tandem Potentiometers have two identical resistor units with the same variation law. The
mismatching of the two resistor units, expressed in dB, is measured by the difference between
the attenuations introduced by each resistor unit at various points of travel.
 Law A: 4 dB at Attenuation range 0 - 20 dB
 Law B and C: 3 dB at Attenuation range 0 - 20 dB
