1113B202

Trimmer potentiometers allow a precise adjustment of electrical equipment by varying electrical resistance. The most common type is the rotary trimmer potentiometer (RTP), also known as a trimpot. These devices are widely used in electronic circuits as variable resistors, trimming potentiometers, and variable capacitors. In this article, we\'ll explore the application field and working principle of the 1113B202 Trimpot, which is widely used in various applications.

Applications of the 1113B202 Trimpot

The 1113B202 Trimpot is a 9mm square ceramic trimmer potentiometer with a 7mm travel range. It is designed for applications requiring a precise adjustment of electrical equipment. The trimpot has a very secure connection, as all parts are welded together.The 1113B202 Trimpot is most commonly used for the following applications:

• Voltage and current level adjustment
• Filter circuit adjustment
• Tuning radio and TV sets
• Feedback control circuits
• Intermittent control circuits
• Analog-to-digital conversion circuits

Working Principle of the 1113B202 Trimpot

The 1113B202 Trimpot has a fixed resistor with a variable wiper contact. The variable wiper contact is connected to a resistance shaft that allows for precise adjustment of the resistance. The resistance is adjusted by turning the knob or shaft, which moves the wiper contact across the resistor. The resistance can be adjusted from 0 ohms up to the maximum value.

The trimpot also has two external terminals which are used to connect the appropriate power supply. When the trimpot is connected to a power source, the wiper contact will be adjusted until the desired resistance is attained. The trimpot can then be used as a variable resistor, trimming potentiometer, or variable capacitor, depending on the application.

Conclusion

The 1113B202 Trimpot is a highly precise trimmer potentiometer that is widely used in a variety of applications. It has a 7mm travel range which allows for precise adjustment of resistance over a wide range. Its two external terminals allow for easy connections to the appropriate power supply, making it an ideal choice for precise adjustment of electrical equipment.
