CONTACT RESISTANCE VARIATION: (CRV)
The apparent resistance seen between the wiper and the resistance element when the wiper is energized with a specified current and moved over the adjustment travel in either direction at a constant speed. The output variations are measured over a specified frequency bandwidth, exclusive of the effects due to roll-on or roll-off of the terminations and is expressed in ohms or % of Rt.

EQUIVALENT NOISE RESISTANCE: (ENR)
(Wirewound only) Any spurious variation in the electrical output not present in the input, defined quantitatively in terms of an equivalent parasitic, transient resistance in ohms, appearing between the contact and the resistive element when the shaft is rotated or translated. The Equivalent Noise Resistance is defined independently of the resolution, functional characteristics and the total travel. The magnitude of the Equivalent Noise Resistance is the maximum departure from a specific reference line. The wiper of the potentiometer is required to be excited by a specific current and moved at a specific speed.

RESISTANCE-TEMPERATURE CHARACTERISTIC: (RTC)
The difference between the total resistance values measured at a reference temperature of 25°C and the specified test temperature expressed as a percent of the Total Resistance.
Where:
R1 = Resistance at reference temperature (25°C) in ohms
R2 = Resistance at the test temperature in ohms

TOTAL RESISTANCE: (Rt)
The dc resistance between the input terminals with the wiper positioned to either end stop, or in dead band for continuous rotation potentiometers.

ABSOLUTE MINIMUM RESISTANCE: (Rm)
The resistance measured between the wiper terminal and each end terminal with the wiper positioned to give a minimum value.

END RESISTANCE: (Re)
The resistance measured between the wiper terminal and an end terminal when the wiper is positioned at the corresponding end of mechanical travel.
Absolute minimum resistance and end resistance are synonymous for continuous rotation trimmers.

TEMPERATURE COEFFICIENT OF RESISTANCE: (TC)
The unit change in resistance per degree celsius change from a reference temperature, expressed in parts per million per degree celsius as follows:



Where:
R1 = Resistance at reference temperature in ohms
R2 = Resistance at test temperature in ohms
T1 = Reference temperature in degrees celsius
T2 = Test temperature in degrees Celsius

New Year is coming soon.Wish you have a wonderful holiday in advance.

Below hot sellers many buyers will buy for resale or stock before New Year. Do you have any demand for those? We will try our best to satisfy you well with competitive prices as per your request.

And we are on the stage of evaluating old distributors and develop more potential new distributors, do you have interests in being kingtronics distributor?
