504 500K ohm Variable Resistor

The 504 500K ohm variable resistor, also known as a potentiometer, is a versatile electronic component used to adjust resistance in a circuit. This device features a three-terminal design with an adjustable middle terminal, allowing for precise control over resistance values from 0 to 500K ohms. It is commonly used in applications requiring fine-tuning and calibration, such as audio controls, sensors, and signal conditioning.

Key Features:

• Adjustable resistance up to 500K ohms
• Three-terminal design for flexible usage
• High precision and reliability
• Suitable for fine-tuning and calibration purposes
• Available in various configurations (rotary, linear)

Technical Specifications:

• Resistance Range: 0 – 500K ohms
• Power Rating: Typically 0.25W (1/4W)
• Tolerance: ±20% (typical)
• Temperature Coefficient: ±100ppm/°C (typical)
• Shaft Type: Knurled, slotted, or smooth
• Mounting Type: Through-hole

Applications:

• Volume control in audio equipment
• Tuning and calibration in electronic circuits
• Adjustable power supplies
• Sensor adjustments
• Signal conditioning

Usage:

1. Solder the three terminals to the appropriate points in the circuit.
2. Rotate or slide the control to adjust the resistance.
3. Use a multimeter to measure the resistance if precise adjustments are needed.

Caution:

• Do not exceed the rated power to avoid damage.
• Handle with care to avoid damaging the resistive element.
• Ensure proper mounting to prevent mechanical stress.
