What is the difference between chip inductors and chip resistors? What are the differences? What is called chip resistors? What is chip inductors? SMD resistor is also a chip fixed resistor, directly translated from Chip Fixed Resistor, commonly known as SMD Resistor, which is a metal glass uranium resistor One kind. It is a resistor made by mixing metal powder and glass uranium powder and printing on the substrate by screen printing. Resistant to humidity, high temperature, and low temperature coefficient. Can greatly save the cost of circuit space and make the design more refined.
　　SMD components have the advantages of small size, light weight, high installation density, strong shock resistance, strong anti-interference ability, good high-frequency characteristics, etc., and are widely used Computers, mobile phones, electronic dictionaries, medical electronic products, camcorders, electronic energy meters, VCD machines, etc. SMD components can be divided into three types according to their shape: rectangular, cylindrical and irregular. There are resistors, capacitors, inductors, transistors and small integrated circuits by type. The nominal methods of SMD components and general components are different.
　　SMD resistor has small size and light weight; suitable for reflow soldering and wave soldering; stable electrical performance, high reliability; low assembly cost, and automatic Matching equipment; high mechanical strength, superior high frequency characteristics and other advantageous characteristics. At present, the model of the chip resistor is not uniform, which is set by each manufacturer, and the model is particularly long (composed of a dozen English letters and numbers). If the various parameters and specifications of the chip resistor can be correctly presented when purchasing, then the required resistor can be easily purchased (or ordered).
　　It is understood that the operating temperature range of the chip resistor is -55--+125℃, and the maximum operating voltage is related to the size: 0201 is the lowest, 0402 and 0603 are 50V, 0805 is 150V, other sizes are 200V. The related information of chip resistors is introduced to you today. Let's take a look at chip inductors.
　　There are 4 types of chip inductors, namely wire wound, laminated, braided and thin film chip inductors. Two types of winding and lamination are commonly used. The former is the product of miniaturization of traditional wire wound inductors; the latter is made by multilayer printing technology and laminated production process, and the volume is smaller than that of wire wound chip inductors. It is a product developed in the field of inductive components.
Characteristics of chip inductors:
　　Surface mount high power inductors. It has the characteristics of miniaturization, high quality, high energy storage and low resistance.
　　Mainly used in computer display boards, laptops, programming, and converters.
The characteristics of chip inductors:
　　Flat bottom surface is suitable for surface mounting. Excellent end surface strength and good solderability. It has the characteristics of high Q value and low impedance.
　　Low magnetic leakage, low straight resistance, high current resistance. SMD inductors can be provided in braided packaging to facilitate automated assembly. SMD inductor products are widely used in digital products, sports equipment and medical equipment.
　　From the above two characteristics, we can understand that although chip inductors and chip resistors belong to the SMD industry, there are still certain applications and differences in essence Differentiation, the same electronic products and industry, maybe these two products can be used.
