Trimmer Potentiometers

The EVM-AASA00BE4 is a trimmer potentiometer that is commonly used in a variety of applications. It is a three-terminal device with 250K Ohm resistor-capacitor combination built in. This trimmer can be used to adjust resistance over a range of 0-250K Ohm, and is available in a variety of package styles including through hole and surface mount.

Application Field

Trimmer potentiometers are used in a variety of applications where precise control of resistance is required. This includes applications such as circuit tuning, controlling gain of amplifier circuits, and temperature regulation. The EVM-AASA00BE4 is particularly well-suited for use in control circuits where space is a factor, since it comes in a relatively small package and consumes little power.

Working Principle

The EVM-AASA00BE4 trimmer potentiometer works on the principle of a voltage divider. It has three terminals: two end terminals and the adjustable middle terminal. When a voltage is applied to the two end terminals, a portion of the voltage is dropped across the adjustable middle terminal, which can be used to adjust the resistance of the circuit. The device has a built-in 250K resistor-capacitor combination, which helps to ensure that the resistance stays consistent over time.

The EVM-AASA00BE4 also has a range of additional features. It has a low contact resistance, which helps to ensure a high level of precision in the adjusted resistance. It also has a low contact bounce, which helps to reduce noise and improve reliability in the circuit. Additionally, the device has positive temperature coefficient of resistance, which helps to ensure consistent performance in varying temperatures.

Conclusion

The EVM-AASA00BE4 trimmer potentiometer is a reliable and versatile device. It offers a variety of features which make it suitable for a range of applications. Its small size and low power consumption makes it ideal for use in space-constrained, or power-sensitive circuits. The device is also designed to ensure consistent performance in varying temperatures, and its low contact resistance ensures high precision in the adjusted resistance.
