Tips for purchasing chip resistors, identification and model of chip resistors 3

4. Resistor size identification: The size of a chip resistor is typically represented by length, width, and height (LWH), for example, "0402" indicates a resistor with a length of 0.04 inches and a width of 0.02 inches. The size is usually marked before or after the resistor body's code, for example, "0402 100" indicates a resistor with a size of 0402 and a resistance of 100 ohms.diode

5. Identification of resistance temperature coefficient: The temperature coefficient of a chip resistor is usually expressed as a ppm/°C value, for example, "±100ppm/°C" indicates a temperature coefficient of ±100ppm/°C. The temperature coefficient is usually marked after the code of the resistor body, for example, "100 100±100ppm/°C" indicates a resistor with a resistance of 100 ohms and a temperature coefficient of ±100ppm/°C.diode

Summary:

When purchasing chip resistors, it is necessary to understand the required parameters such as resistance value, accuracy, power, size, and temperature coefficient, and identify them by checking the markings on the resistor body. Additionally, one can refer to the resistor coding table provided by the manufacturer for identification. Purchasing the appropriate chip resistor can ensure the normal operation and performance of electronic devices.diode
