Trimmer Potentiometers are small adjustable resistors oftentimes used to create adjustable voltage divider circuits and adjustable current paths. The SM-43TX201 is a specific type of trimmer potentiometer manufactured by Nidec Copal Electronics. This state-of-the-art trimmer potentiometer is designed for high performance and reliability and is very useful in commercial and industrial applications.

The SM-43TX201 offers resistance adjustment over a much wider range than conventional potentiometers. It produces an adjustable amount of power between 0.1 mW and 5 watts and can be used for audio signals as well as for signal measurement and instrumentation. Its adjustable range is 0Ω 500kΩ. The operation temperature for the SM-43TX201 ranges from -55° to +125° Celsius.

This trimmer potentiometer features a single turn, dual gang top-adjust, and locking screw contact design. It features a one-piece aluminum case construction that is both light-weight and durable. The contact material is a gold-plated copper alloy that is corrosion-resistant and highly reliable. The SM-43TX201 is also RoHS compliant, which means it is free of hazardous substances and can be safely used in any environment.

The working principle of the SM-43TX201 is based on the following two main concepts: resistance and voltage divisions. The resistance of the potentiometer is divided between two terminals, the “low” and “high” terminals, with the adjustable “middle” terminal providing a variable resistance. When the middle terminal is adjusted, the resistance is varied between the high and low terminals.

The voltage division is also based on the same basic concept. When a voltage is applied across the high and low terminals, the visible voltage at the middle terminal will vary in accordance with the position of the trimmer. In other words, as the trimmer is adjusted, the voltage division changes between the two terminals and the resultant voltage will be different.

The SM-43TX201 is an ideal choice for applications requiring adjustable resistance or adjustable voltage division. Due to its wide resistance range and relative simplicity, this trimmer potentiometer is often used in industrial and commercial applications such as circuit protection, voltage regulation, as well as in audio circuits. Moreover, due to its light weight construction and RoHS compliance, it is also suitable for portable electronic devices.

The SM-43TX201 is perfect for applications requiring variable resistances or variable voltage divisions across a wide range. With its high reliability, simple operation and durable construction, the SM-43TX201 is an excellent trimmer potentiometer for any application.
