Multiturn Adjustment : 
Requires more than 360° mechanical adjustment to cause the wiper to traverse the total resistance element.

Terminal : 
An external member that provides electrical access to the resistance element and wiper.

Leadwire Type: (L)
Flexible insulated conductor.

Resistance Element :
A continuous, unbroken length of resistive material without joints, bonds or welds except at the junction of the element and the electrical terminals connected to each end of the element or at an intermediate point such as a center tap.

Adjustment Shaft :
The mechanical input member of a trimming potentiometer which when actuated causes the wiper to traverse the resistance element resulting in a change in output voltage or resistance.

Single Turn Adjustment :
Requires 360° or less mechanical input to cause the wiper to traverse the total resistance element.

Trimming Potentiometers:
An electrical mechanical device with three terminals. Two terminals are connected to the ends of a resistive element and one terminal is connected to a movable conductive contact which slides over the element, thus allowing the input voltage to be divided as a function of the mechanical input. It can function as either a voltage divider or rheostat.

Wirewound Trimming Potentiometer:
A trimming potentiometer characterized by a resistance element made up of turns of wire on which the wiper contacts only a small portion of each turn.

Non- Wirewound Trimming Potentiometer:
A trimming potentiometer characterized by the continuous nature of the surface area of the resistance element to be contacted. Contact is maintained over a continuous, unbroken path. The resistance is achieved by using material compositions other than wire such as carbon, conductive plastic, metal film and cermet.

The combination of proprietary cermet element technology, precious metal brush contacts and swaged pin element connections used in BI trimmers permits the manufacture of precision, high quality trimmers that span the resistance range from 10 ohms to over 5 megohms. The small size and planar construction of these trimmers minimize stray circuit reactances and permit the trimmers to perform well in many high frequency applications.

Leadscrew
Precision brass leadscrew cuts its own grooves in the teflon rotor so that the operation of the rotor is free of backlash. Setability is excellent.

Sealing Grooves
Leadscrew has specially cut grooves to ensure a watertight seal.

Ceramic Substrate
High density substrate provides an excellent base for the element and is a good conductor of heat.

Cermet Element
BI’s proprietary cermet element matches the materials in the wirebrush so that CRV is minimized and the high temperature setability is excellent.

Swaged Pins
BI’s pin connections, which are swaged to the substrate, are free of solder and maintain high conductivity with time and temperature cycling.

A good supplier should be equiped with competitive price, fine quality, quick lead time & nice packing.

Since 1990, Kingtronics owns 2 ISO factories, trimmer output is 5kkpcs/mth, faster L/T & better price than Bourns, Vishay, Murata... 

That's why we gain more and more customers from Europe, America, South Africa, Asia.

Saving cost means profit increase. All we can support is what you want. Why not move forward together~!
