How to see the model of resistor
Resistors are one of the common components in electronic circuits, and their model identification is crucial for engineers, repairers and electronic enthusiasts. This article will introduce in detail the method of viewing resistor models, and combine popular topics and hot contents across the network for the past 10 days to help readers quickly master relevant skills.
1. Basic composition of resistor model
The resistor model is usually composed of the following parts: resistance value, tolerance, power and temperature coefficient. Here are common ways to represent resistor models:
| Components | illustrate | Example |
|---|---|---|
| Resistance value | Indicates the resistance value of the resistor, commonly used color ring or digital | 10kΩ, 470Ω |
| tolerance | Indicates the allowable deviation range of resistance value | ±5%, ±1% |
| power | Indicates the maximum power that the resistor can withstand | 1/4W, 1W |
| Temperature coefficient | Indicates the stability of resistance value with temperature | 100ppm/°C |
2. How to view resistor model
1.Identification of color ring resistors
The color ring resistor indicates resistance and tolerance through the ring bands of different colors. The following is the identification method of color ring resistor:
| Color ring color | number | Multiplied | tolerance |
|---|---|---|---|
| black | 0 | 10^0 | - |
| brown | 1 | 10^1 | ±1% |
| red | 2 | 10^2 | ±2% |
| orange color | 3 | 10^3 | - |
| yellow | 4 | 10^4 | - |
2.Identification of digital resistors
Digital resistors usually use three or four digits to represent the resistance value. For example:
