Tips for purchasing chip resistors, identification and model of chip resistors 2

5. Pay attention to the temperature coefficient of the resistor: The temperature coefficient of a resistor indicates the degree to which the resistance value changes with temperature. Common temperature coefficients include ±100ppm/°C, ±200ppm/°C, etc. The smaller the temperature coefficient, the better the stability of the resistor. Choose the appropriate temperature coefficient based on specific needs.

II. Identification and Model of Chip Resistors diode

1. Resistance value identification: The resistance value of a chip resistor is usually marked on the resistor body, which can be directly identified by checking the markings on the resistor body. Generally, there will be a code with numbers and letters on the resistor body, such as "100" for 100 ohms, "10K" for 10 kiloohms, "4M7" for 4.7 megohms, etc. It should be noted that different manufacturers may use different marking methods for resistors, and you can refer to the resistor coding table provided by the manufacturer for identification.diode

2. Resistance accuracy identification: The accuracy of chip resistors is usually expressed as a percentage value, such as "1%" indicating 1% accuracy, "5%" indicating 5% accuracy, etc. The accuracy is usually marked after the code of the resistor body, for example, "1001" indicates a resistor with a value of 100 ohms and an accuracy of 1%.

3. Resistor power identification: The power of a chip resistor is usually expressed as a watt value, such as "1/8W" indicating a power of 1/8 watt, "1/4W" indicating a power of 1/4 watt, and so on. The power is usually marked before the code of the resistor body, for example, "1/8W 100" indicates a resistor with a power of 1/8 watt and a resistance of 100 ohms.diode
