Trimmer potentiometers are a type of component used in many systems to adjust and measure changes in electrical signals. They usually consist of three electrical terminals, with one of the terminals connected to a knob or rotary switch that can be used to adjust the resistance, or resistance range, in the circuit to which it is connected. The CT94EW202 is a trimmer potentiometer from anisotropic conductive film manufacturer Copal Electronics, specifically designed for use in consumer electronics and other devices with space limitations.

The CT94EW202 is an incredibly small trimmer potentiometer, only 4.2 x 3.2 mm in size, making it suitable for use in many consumer electronics systems where space is limited. This trimmer can be adjusted over a full range of resistance values, from 0 – 1000 ohms, thanks to its conductive film technology and integral adjustment knob. This makes it ideal for use in devices with variable resistance values, such as audio and electronics.

The CT94EW202 is a two-terminal device, meaning that it only requires two components to connect it to the circuit. This makes it easier and faster to assemble in production compared to other larger potentiometers. This trimmer is particularly suited to use in electronic devices with features that require high levels of adjustment accuracy, such as equalizers, and other parametric controls in audio systems.

The working principle of the CT94EW202 is simple and straightforward. The device consists of an adjustable central terminal that is connected to a switchable resistive element. This can be adjusted with the integrated knob, allowing the resistance to be varied over a range of 0-1000 ohms. The other two terminals are connected to the source of the signal and the load respectively. When the knob is turned, the resistance of the element changes, resulting in the appropriate voltage or current being transferred to the load.

The CT94EW202 is a potentiometer suitable for a wide range of consumer electronics applications. It can be used in audio systems, digital music players, television sets and video game consoles, as well as other devices with limited space. Its small size makes it ideal for use in such applications where the device needs to be adjusted for optimal performance. The integral adjustment knob allows for easy and precise adjustment over a full range of resistances, while its two-terminal connection makes assembly straightforward and cost-effective. The CT94EW202 therefore offers an easy and effective way to adjust resistance in consumer electronics applications.
