Trimmer potentiometers enable us to easily adjust the resistance values of circuits. As the name implies, they can help us to trim the resistance values. We can adjust the resistance values in a very precise manner. As such, these devices can be used in a wide range of applications, from high-end medical equipment to automotive and aerospace systems. This article provides a detailed description of EVM-3SSX50BC2, including its application field and working principle.

Application Field

The EVM-3SSX50BC2 is a high performance, three-layer multilayer trimmer potentiometer manufactured by EDI. This trimmer is available in various resistance values, ranging from 100 to 5 kOhms. It has an operating temperature range of -55°C to +125°C and a nominal resistance tolerance of ±3%. This device is suitable for use in any application requiring precise setting of the resistance by means of a rotary knob.

The EVM-3SSX50BC2 trimmer can be used in a wide variety of applications, such as electronic filters, timing circuits, stereo circuitry, oscillators, remote control systems, HVAC systems, and audio equipment. This trimmer is also used in medical equipment, automotive systems, telecommunications systems, and aerospace systems.

Working Principle

As the name implies, trimmer potentiometers are used for trimming the resistance values. They work by changing the resistance value through a mechanical rotation of the adjuster knob. The different resistance values are achieved by providing a discrete set of indentations in the rotating shaft of the trimmer potentiometer.

The EVM-3SSX50BC2 trimmer consists of 3 layers. Layer 1 consists of a top layer and a bottom layer, in which one of the resistance tracks is fully exposed, while the other resistance track is partially exposed. Layer 2 consists of a top and bottom layer, in which both of the resistance tracks are completely exposed. Layer 3 consists of a top and bottom layer, in which one of the resistance tracks is fully exposed, while the other resistance track is partially exposed.

The EVM-3SSX50BC2 trimmer works by relying on the electric field between the two layers to bridge across the resistance tracks. In addition, the direction of current flow through the resistance track can be changed, depending on which layer is connected to the positive or negative terminal of the power supply. As the adjuster knob is rotated, the amount of resistance is varied according to the different indentations on the rotating shaft.

EVM-3SSX50BC2 is an ideal choice for those who need a precision device that will provide reliable results. It is designed to operate within extreme temperatures and is capable of providing reliable results without any significant drift in terms of resistance values. With its multiple layers, it is also highly durable and resistant to shock and vibration, making it suitable for use in harsh environments.
