Trimmer Potentiometers

Trimmer potentiometers, also known as trim pots, are adjustable resistors with rotary or linear operating mechanisms. Their working principle is based on a mechanical variable resistor, enabling users to fine-tune the resistance value of the circuit. The 39WNBBR10KLF30 unit, in particular, is a trimmer potentiometer of the horizontal PC mount type. Its variable resistance range, from 10 kiloohms to 30 kiloohms, is suitable for both stereo and mono applications. It is often used in vibration control circuits, audio applications, and sound-level based equipment calibration. The 39WNBBR10KLF30 unit also offers excellent linearity and low power consumption; it is capable of dissipating up to 3 watts of power. In addition, its shock absorber reduces the impact of vibration on the unit and ensures a smooth operation.Trimmer potentiometers are designed to fit into printed circuit boards (PCBs). Typically, their circuit board size ranges from 10 to 30 mm, and their pin pitch ranges from 2.54mm to 5.08mm. In the case of the 39WNBBR10KLF30 trimmer, the circuit board size is 10 x 35 mm and the pin pitch is 2.54mm. In addition, the installation hole size is 6mm in diameter, which is similar to that of other trimmer potentiometers.The function of a trimmer potentiometer is to adjust in a certain direction that can be adjusted after the installation of the PCB. The 39WNBBR10KLF30 trimmer potentiometer also adjusts using a standard potentiometer handle. Connecting its two pins allows the user to control the resistance value accurately. Different resistances can be achieved by rotating the knob counterclockwise until the "OFF" position is reached.Apart from that, various features are also pre-installed inside the 39WNBBR10KLF30 trimmer potentiometer. These include reverse swing protection, low NF (30dB) noise, and an anti-interference protective sheath. The reverse swing protection ensures that the knob is turned clockwise for an increase in resistance and anti-clockwise for a decrease. The low NF noise, meanwhile, allows for a stable adjustment of the resistance values. Finally, the anti-interference protective sheath protects the unit from static electricity or electromagnetic interference.In conclusion, the 39WNBBR10KLF30 trimmer potentiometer is an adjustable resistor with a PCB size range of 10-30mm and a pin pitch of 2.54mm. It has countless features, such as reverse swing protection, low NF noise, and an anti-interference protective sheath, making it ideal for modular circuits in audio applications, vibration control circuits, and sound-level based equipment calibration.
