1. Characteristics of chip fixed resistors?
Characteristics of chip fixed resistors mainly include small size, light weight, adaptability to reflow soldering and wave soldering, stable electrical performance and high reliability, low assembly cost, compatibility with automatic mounting equipment, high mechanical strength, and superior high-frequency characteristics.
Chip fixed resistors are small and light, which facilitates the layout and installation of circuits and saves space. Adapting to the technical requirements of reflow soldering and wave soldering makes them highly applicable in modern electronic manufacturing processes. The stability and high reliability of electrical performance ensure the long-term stable operation of the circuit and reduce the failure rate. The low assembly cost and compatibility with automatic mounting equipment improve production efficiency and reduce manufacturing costs. -
2. Chip fixed resistor classification?
1. Conventional series thick film chip resistors: including general-purpose resistors in sizes from 0201 to 0805, and resistors in sizes from 1206 to 2512.
2. High-precision and high-stability chip resistors: These resistors have high precision and high stability, with sizes ranging from 0201 to 0603, 0805 to 1210, and 2010 to 2512.
3. Conventional series thin film chip resistors: This refers to general-purpose thin film chip resistors with a wide range of sizes from 0201 to 2512.
4. Low resistance chip resistors: Suitable for circuit applications requiring low resistance values, with sizes ranging from 0402 to 1206, and 2010 to 2512.
5. Chip resistor arrays: Including raised and recessed chip resistor arrays, used in circuits that require multiple resistance values to work simultaneously.
6. Chip current sensor: used to detect the current in the circuit, with low temperature coefficient (TCR) characteristics. -
3. Resistance value representation method
In the digital identification of chip resistors, the first three digits are usually used to indicate the resistance value. These digits are interpreted in decimal, such as "100" means the resistance value is 100 ohms. In some cases, if the resistor value is large, "R" may be used to indicate the decimal point position, such as "1R0" for a resistor value of 1.0 ohm.

4. Resistor tolerance accuracy representation method
The tolerance accuracy of chip resistors refers to the allowable deviation range between the actual value of the resistor and the nominal value. In the digital identification, the tolerance accuracy is usually indicated by the last one or two digits. These numbers correspond to different accuracy levels, for example, 1% accuracy is usually indicated by the number "1", while 0.1% accuracy is indicated by the number "01".
