Common Resistor Values
Explore the most frequently used resistor values in electronics. Each resistor includes detailed specifications, color codes for all band configurations, and practical applications.
Low Resistance (1Ω - 100Ω)
Power applications, current sensing, and low-impedance circuits
Medium Resistance (220Ω - 4.7kΩ)
LED circuits, pull-up/pull-down resistors, and general purpose
High Resistance (10kΩ - 1MΩ)
High-impedance circuits, precision applications, and low-power design
Understanding Standard Resistor Values
E12 Series Standard
The E12 series is the most common standard for resistor values, providing 12 values per decade with approximately 10% spacing. This series covers the most frequently used resistor values in electronic circuits.
These standard values ensure compatibility across different manufacturers and applications, making them readily available and cost-effective for most electronic projects.
Choosing the Right Value
Selecting the appropriate resistor value depends on your specific application. Consider factors such as current requirements, voltage drops, power dissipation, and circuit impedance.
Each resistor value page provides detailed information about color codes, specifications, and practical applications to help you make the right choice for your project.
