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.

Every country has its own national day which stands for the beginning of nation, so the National Day is very important for a country to celebrate.

Trimmer potentiometers and preset resistors are small variable resistors which are used in circuits for tuning and (re)calibration.

Types of Trimming Potentiometer

Several different versions of trimmer are available, using different mounting methods (through hole, smd) and adjusting orientations (top, side) as well as single and multi-turn variation.

1》Open, carbon track
2》Enclosed, side adjust
3》Enclosed, SMD

Single turn

Single turn trimmers/presets are very common and used where a resolution of one turn is sufficient. They are the most cost effective variable resistors available.

Multi turn

For higher adjustment resolutions, multi-turn Trimming Potentiometers are used. The amount of turns varies between roughly 5-25, but 5, 12 or 25 turns are quite common. They are often constructed using a worm-gear (rotary track) or (linear track) mechanism to achieve the high resolution. Because of their more complex construction and manufacturing, they are more costly than single turn preset resistors. The lead screw packages can have a higher power rating because of their increased surface area.

Trimming potentiometer symbols

The following IEC symbols are used for trimmers and preset resistors. Although this are the official symbols for occasionally adjusted resistors, the standard symbols for a potentiometer or rheostat are often used.
