Trimmer Potentiometers

Trimmer potentiometers are used in circuits to adjust the voltage or enable current to a certain level, and can be used for countless applications which require accurate analog control. A trimmer potentiometer, also known as the trim pot, trimmer resistor, variable resistor, adjustable resistor, or preset, is a type of resistor which has an adjustable resistance, depending on the user\'s adjustment.

72RPXR100KLF Trimmer Potentiometers

The 72RPXR100KLF trimmer potentiometers come with six and three terminal configurations. Six terminal configuration models are designed with two separate leads for adjustable and stationary resistances as well as four terminals. The three terminal models have adjustable, fixed and one center wiper terminal.

These trimmer potentiometers have a rated resistance range of 100Kohms, and come with a standard outside configuration of 21mm in diameter. The rotation life is 15,000 cycles and the insulation resistance is higher than 100Mohm. The tolerance which comes with this range of trimmer potentiometers is 10%; this measures the resistance difference between the actual value and the stated value.

Application Fields & Working Principle

The 72RPXR100KLF trimmer potentiometers are used for various applications such as pre-setting of circuits for increased stability, adjustment of current and voltage, and adding resistance or capacitance for radio broadcast tuning.

This range of trimmer potentiometers can be used for any circuit requiring adjustable preset analog control. It can be used in analog sound production systems such as mixers and audio equalizers to control the Loudness, Bass and Treble settings.

The 72RPXR100KLF trimmer potentiometers are variants on the classic potentiometer circuit. These resistors consist of a fixed resistor element and a variable resistor element which are connected via a wiper. When the wiper is moved, the resistance of the two elements changes and causes the resistance of the complete trimmer potentiometer to change. This variable resistance in turn changes the voltage across the potentiometer.

The amount of resistance is determined by the resistance between the wiper and either of the terminal resistors. When the wiper is close to the contact and then adjusted to the end, the resistance in the circuit changes, and as a result, the current is regulated.

The 72RPXR100KLF trimmer potentiometers are suitable for use in applications where accuracy is important as they offer higher precision and power handling capabilities. These resistors are generally used in conjuction with other resistors and capacitors in order to adjust voltage or enable current.
