Introduction

Trimmer Potentiometers, or trimpots, are adjustable resistors used for the control of voltage, current, and temperature in circuits. The EVN-5CSX50B14 is a single-turn trimmable 3-terminal device used for simple resistance value adjustments in a wide range of applications.

Application Field

The EVN-5CSX50B14 is typically used in a variety of electronic and industrial applications. Examples include radio frequency signal generators, receivers, diodes, transistors, oscillators, amplifiers, and motor drivers. Its versatile design makes it especially useful for precision adjustments of variables in radio communication systems, audio and video playback systems, and RFID (radio frequency identification) systems.

Features

The EVN-5CSX50B14 offers a wide range of features, including:

• Adjustable resistance range: 10 – 1,000 ohms
• High-precision linearity: ± 5%
• Low-noise operation
• Low-temperature drift
• High-temperature stability
• LED option for visual indication and control
• Easy-to-use mounting options

Design

The EVN-5CSX50B14 is designed with a three-terminal configuration and an adjustable resistor housed in a rugged plastic enclosure. It features a flat circular top plate with a non-slip knurled grip, a reliable adjustable resistor, and a built-in LED indicator. The trimpot is rated for 3A operation at 250 Vac, up to 15W, and has up to 3.5" of adjusted length.

Working Principle

The EVN-5CSX50B14 operates by changing the resistance in the adjustable element using a mechanical contact. It features a two-stage adjustment system that allows for coarse and fine adjustment of resistance. By rotating the top plate, the contact slides across the adjustable element to set the desired resistance. The adjustable element is sealed in the plastic enclosure to protect it from environmental contaminants. Additionally, the device features an LED indicator which lights when the resistance is adjusted, providing a visual indication of the setting.

Conclusion

The EVN-5CSX50B14 is an adjustable 3-terminal trimmer potentiometer designed for applications requiring precision control. It offers a wide range of features, including a resistance range of 10 – 1,000 ohms, a linearity of ± 5%, low-noise operation, low-temperature drift, high-temperature stability, and an LED option for visual indication and control. Its versatile design makes it a useful component for precision adjustments of radio communication, audio and video playback, and RFID systems.
