To learn chip resistors, please see**:
We will explain in detail the concept of chip resistors, the process flow, and the nominal values of the e-series.
First, let's take a look at chip resistors. A chip resistor is an electronic component that is typically used to adjust voltage and current in a circuit. It is made of a metal diaphragm and semiconductor material, and can be mounted by sintering a chip on a circuit board. Chip resistors are widely used in a wide range of electronic devices due to their small size, accurate current limit, and high reliability.
Next, we will introduce the process flow of chip resistors. First, choose the appropriate resistive material, such as graphite, copper, etc. Then, the resistive diaphragm is attached to the circuit board with a precision placement machine and sintered. Finally, a visual inspection and testing is carried out to ensure that the performance of the resistor meets the requirements.
Finally, let's take a look at the e-series nominal values. The nominal value of the E-series chip resistors is from 0It ranges from 25W to 150W, and is mainly used in various scenarios such as electronic equipment, household appliances, and lighting equipment. The greater the nominal value of the resistor, the smaller its resistance and vice versa. When selecting a chip resistor, it is necessary to select the appropriate nominal value according to the actual needs to ensure the normal operation of the circuit.
In short, chip resistors are very important electronic components, and their concepts, process flows, and e-series nominal values are very worthy of our in-depth understanding. I hope today's explanation can be helpful to everyone!
Of course, I'll be happy to explain chip resistors to you.
A chip resistor is a type of passive component that is widely used in electronic devices, often used for functions such as limiting current, changing circuit characteristics, and attenuating voltage. It consists of a small resistive element, two electrodes, and a conductive material. Compared to traditional plug-in resistors, chip resistors are smaller, more space-saving, and easier to automate production and welding.
The production process of chip resistors is as follows:
1.Substrate preparation: Ceramic or organic materials are usually used as the basic resistive elements, and a thin layer of metal is added to their surface as the resistive material.
2.Sheet pressing and cutting: The substrate material is processed into resistors of standard size and shape through processes such as pressing and cutting.
3.Printing: A conductive material is applied to a resistive sheet through a printing process to form a sufficient resistance value.
4.Cutting and trimming: The printed resistor sheet is made into a chip resistor with a standard resistance value through cutting, trimming and other processes.
5.Surface treatment: In order to protect the resistors and improve the welding performance, surface treatments, such as electroplating, are usually applied to the chip resistors.
6.Packaging & Testing: Put the chip resistors in the appropriate packaging and do the testing and quality checking.
The nominal value of the chip resistor is usually expressed using the e-series. The e-series is available in several different sizes, including E6, E12, E24, E48, E96 and E192. The E-Series specifies a range of values for the resistors and steps them in a certain proportion. The common E24 series contains 24 resistance values, each with a scale of 11 times. For example, for a 100 ohm chip resistor, the closest E24 nominal values are 91 ohms and 110 ohms.
