RT22C2W203

Trimmer potentiometers are adjustable voltage dividers. RT22C2W203 is a suitable miniature trimmer potentiometer suitable for low current applications. It is a three-terminal device that can be used to provide a variable resistance or a voltage divider for small signal levels. It comes with a choice of resistance values including 20 ohm, 50 ohm, 100 ohm, 150 ohm or 200 ohm. And it has a package size of 9.7mm x 4.3mm, 2mm pitch.

The RT22C2W203 application field is primarily for frequency setting and balance setting in electronic equipments. It is also suitable for adjusting of electrical parameters and being used as voltage divider in circuits with very low power drain. This device can also be used in power supply current limitation and temperature control circuits.

The working principle of the RT22C2W203 is based on the series principle: the total resistance is equal to the sum of the resistances of all elements in the potentiometer. When using the trimmer into a voltage divider, the current flows through the fixed resistors and the adjustable one, then is separated into two parts at the junction point. The ratio of the two output voltages is determined by the adjustable resistance.

In addition, the RT22C2W203 is a three-pin, non-contacting inductive sensing element. Its terminals – the V1 (left), I/+ (center) and I/- (right) correspond respectively to the voltage output, positive and negative current output. The device provides reliable potentiometer action with its shielded tracks, positive detent, and dust guard.

Therefore, the RT22C2W203 trimmer potentiometer is ideal for various applications such as frequency setting and balance control in electronic devices. It offers high reliability and resolution and is perfect for low current applications.
