The 4K08T-1-2002BC is a trimming potentiometer manufactured by Bourns Inc. Trimming potentiometers, or trimmers, are adjustable resistors used to fine-tune circuits during calibration or setup. They are designed to be adjusted infrequently, typically during the manufacturing or servicing of a product.

Applications:

• Calibration of circuits
• Adjusting voltage levels
• Setting current limits
• Fine-tuning audio equipment
• Precision control circuits

Features:

• Trimming potentiometer (Trimmer)
• Through-hole mounting
• Adjustable resistance
• Compact size
• Sealed construction (likely)

Benefits:

• Allows for precise adjustment of circuit parameters.
• Enables fine-tuning to compensate for component tolerances.
• Provides a means to calibrate circuits for optimal performance.
• Small size makes it suitable for space-constrained applications.
• Sealed construction protects against environmental contaminants (if applicable).

Technical Specifications:

The '2002' in the part number indicates the resistance value. It is calculated as 20 x 10^2 ohms, equaling 2 kΩ (kiloohms). The 4K08T signifies a specific package and style of trimmer. '1' usually represents a specific pin configuration. The BC likely represents the packaging or tolerance information. Refer to the Bourns datasheet for precise specifications, including tolerance, power rating, temperature coefficient, and mechanical dimensions, as well as adjustment characteristics.

The 4K08T-1-2002BC is frequently used in circuits where precise adjustments are required. It allows the circuit to be calibrated to achieve the desired performance. These trimmers are designed for infrequent adjustment, typically during production or maintenance.
