Trimmer Potentiometers

A trimmer potentiometer is a small, adjustable electrical component for precise electrical resistance tuning, ranging from a few ohms to several megaohms. Trimmer potentiometers are useful for applications where a constant variable resistor is needed such as in some types of filters or amplifiers.

3266Z-1-201LF: Application Field and Working Principle

3266Z-1-201LF is a type of trimmer potentiometer manufactured by Bourns. It is a surface mount trimmer potentiometer, for adjustable resistance tuning in applications where space is a concern, such as portable electronics or where space is critical. This type of trimmer potentiometer is designed for manual or automatic adjustment of resistance and has a low profile. It is ideal for applications where high resolution is required, and can be adjusted with a simple turn of a screwdriver.

The 3266Z-1-201LF features resistance values of 50 ohms to 250K ohms, with a resolution of 3/4 turn for every 1 ohm of resistance. It consists of two elements: a resistive element and a conductive element. The resistive element is the circuit\'s main impedance and is designed to absorb changes in resistance. The conductive element is the variable resistor or potentiometer, which is a combination of two opposing resistors. This combination creates a voltage divider, which divides the input voltage into two, where the output voltage is proportional to the input voltage. The conductive element thus forms a voltage divider, allowing for precise variable resistance control.

The 3266Z-1-201LF trimmer potentiometer is available in three shaft lengths: 10, 20 and 30mm. It has a solderable or piezo adjuster, making it easy to install and adjust. The trimmer can also be adjusted by means of an external turn knob or with automatic adjustment equipment, such as using a stepper motor and/or a microcontroller. It is a reliable and low-cost component with a wide range of applications, including audio amplifiers, signal conditioning, voltage and current regulation, impedance matching, transducer control, automatic filter tuning, and so on.

The 3266Z-1-201LF trimmer potentiometer is a reliable and cost-effective solution for space-constrained applications and high-resolution electrical resistance tuning. It is designed for manual or automatic adjustment of resistance and has a low profile and wide range of resistance values. With its adjustable resistance, the 3266Z-1-201LF can be used in a variety of devices for precise electrical resistance tuning and control.
