Trimmer Potentiometers
Trimmer Potentiometers, also known as trimpots or presetting potentiometers, are a type of variable resistor which are used for adjusting circuit parameters. In general, they are small, plastic-bodied components with three terminals, and operated with a small screwdriver. The 3296W-1-253ALF is a standard example of a trimpot, and is widely employed in many industries.
This particular model from Bourns Inc. is a rotary trimmer which features three terminals: two are for the two ends of the resistive element and the third one is the wiper which slides along the resitor’s track when you turn the adjustment screw. Its features include a resistance tolerance of ±10%, and an operating temperature range between -55°C to +125°C.
The 3296W-1-253ALF is a 16-turn, 10K Ohm trimmer potentiometer, with an operating life of up to 20k cycles. Its body size is small enough for PC board mounting, and its high resistance values are ideal for setting the gain of amplifiers and filters, adjusting circuit sensitivity, calibrating receivers and more. Other applications can be found in the fields of automotive, consumer electronics, telecommunications, avionics and industrial equipment.
Trimmer potentiometers have a wide range of applications, but how do they actually work? The main principle behind their functioning is simple: the adjustment screw is turned to change the resistance between the two terminals which are connected to the wiper. The wiper is then swept along the resistive element, in order to reduce resistance at one end and increase it at the other.
The resistance value of the trimmer can also be manually adjusted by rotating the external adjusting screw. This can be done in relation to a fixed measured value already stored in the potentiometer, and it is used to balance the amount of current that flows through the circuit. It is also useful when there is need to manually compensate for any error in a circuit. This action changes the resistance value, thus allowing for a fine-tuning of the circuit parameters.
The final purpose of trimmer potentiometers is to modify the resistance in a circuit, but they should be used with caution. If used improperly, this can cause permanent damage to the potentiometer and to the circuit it supports. For this reason, the 3296W-1-253ALF and other similar models come with a datasheet that provides detailed instructions on the layout, application and handling of these potentiometers.
In conclusion, trimmer potentiometers such as the 3296W-1-253ALF allow users to precisely adjust their circuit parameters. They are widely used in automotive, consumer electronics, telecommunications, avionics and industrial equipment applications. The working principle behind them is very simple: the adjustment screw is turned to change the resistance between the two terminals which are connected to the wiper, while the resistance value is manually adjusted by rotating the external adjusting screw. When used properly, these potentiometers can offer excellent results and prove to be very beneficial.
