Power Rating: 1/4 Watt (0.25W) Suitable for low-power circuits, ensuring safe dissipation of up to 0.25 watts.
Tolerance: ±5% Indicates the resistance can vary within 5% of the specified value, balancing accuracy and cost.
Material: Typically made from carbon film, metal film, or metal oxide, ensuring durability and stability.
Temperature Coefficient: Usually, ±100 to ±200 ppm/°C, indicating how much the resistance value changes with temperature variations.
Color Code Resistors use a color-coding system to indicate their resistance value, tolerance, and sometimes reliability or failure rates. The color code for a 3.9KΩ resistor with ±5% tolerance is as follows:
First Band (Orange): Represents the first significant digit, which is 3.
Second Band (White): Represents the second significant digit, which is 9.
Third Band (Red): Represents the multiplier, which is 2^10 or 100.
Fourth Band (Gold): Represents the tolerance, which is ±5%.

Description
Resistors are crucial components in electronic circuits, used to control current flow, adjust voltage levels, and protect components from damage due to excessive current. The 3.9KΩ (3900 ohms) resistor is a commonly used value, offering moderate resistance suitable for various electronic applications, such as signal processing, biasing transistors, and creating voltage dividers. This resistor has a power rating of 1/4 watt, meaning it can safely dissipate up to 0.25 watts of power. The ±5% tolerance indicates that the actual resistance can vary by 5% above or below the nominal value.Features:
