The EVM2WSX80B23 is a surface-mount trimmer potentiometer manufactured by Panasonic. It's a small, adjustable resistor used for fine-tuning circuits and calibrating electronic devices. Trimmer potentiometers, also known as trimpots, allow for precise adjustments of resistance values, and are commonly used during manufacturing or servicing to compensate for component tolerances or to optimize circuit performance.

Applications

• Calibration of Sensors: Used to calibrate sensors such as temperature sensors, pressure sensors, and light sensors.
• Fine-tuning Audio Circuits: Adjusting gain, bias, or frequency response in audio amplifiers and equalizers.
• LCD Brightness and Contrast Adjustment: Adjusting display settings in LCD monitors and other display devices.
• Power Supply Calibration: Setting output voltage and current levels in power supplies.
• Control Circuits: Used in various control circuits to fine-tune parameters such as timing, sensitivity, or offset.

Features

• Surface Mount Design: Allows for automated placement and soldering on printed circuit boards.
• Small Size: Enables compact designs in portable and space-constrained applications.
• Enclosed Construction: Protects the resistive element from dust and contamination.
• Precise Adjustment: Provides fine-tuning capabilities for accurate calibration.
• RoHS Compliant: Meets environmental regulations for hazardous substances.

Benefits

• Accurate Calibration: Enables precise adjustment of circuit parameters.
• Improved Performance: Optimizes circuit performance by compensating for component tolerances.
• Reduced Manufacturing Costs: Simplifies the manufacturing process by allowing for adjustments after assembly.
• Enhanced Reliability: Ensures stable performance over a wide range of operating conditions.
• Compliance with Environmental Regulations: Meets environmental requirements for hazardous substances.

Additional Details

The EVM2WSX80B23 has a resistance value of 2k ohms. The tolerance is typically +/- 25%. It is designed to withstand reflow soldering processes. This trimmer potentiometer is often adjusted using a small screwdriver. The operating life is dependent on the number of adjustment cycles. This trimpot is designed for single-turn or limited multi-turn adjustment, not continuous rotation. The package is designed to be compatible with standard SMT assembly processes.
