• Power rating of 1/4 watt (0.25W)
• Available in different tolerance values (e.g., ±1%, ±5%)
• Suitable for general-purpose applications
• Available in various physical sizes and types (e.g., axial, surface-mount)

Technical Specifications:

• Resistance: 620Ω
• Power Rating: 1/4 watt (0.25W)
• Tolerance: Typically ±1% or ±5% (varies by manufacturer)
• Temperature Coefficient: Varies by type, typically ±100ppm/°C
• Body Size: Varies by type; common through-hole size is around 6.3mm x 2.5mm (for axial resistors)

Applications:

• Current Limiting: Protects sensitive components by limiting the amount of current that flows through them.
• Voltage Division: Used in voltage divider circuits to create specific voltage levels.
• Signal Conditioning: Helps in signal conditioning circuits to adjust signal levels and impedance.
• Pull-up/Pull-down Resistors: Used in digital circuits for setting logic levels.

Usage:

1. Identify the required resistance value and power rating for your application.
2. Choose the appropriate resistor type (through-hole or surface-mount) based on your PCB design.
3. Place the resistor in the correct position on the PCB or circuit board.
4. Solder the resistor’s leads to the PCB, ensuring proper placement and connection.
5. Verify circuit performance to ensure the resistor is functioning as intended.

Caution:

• Ensure the power rating of the resistor is adequate for your application to avoid overheating and damage.
• Verify the resistance value and tolerance to match circuit requirements.
• Handle with care to avoid mechanical damage.
