Detailed explanation of the size code for surface mount resistors?

Surface mount resistor size codes? We have previously provided a brief introduction to this question, but found that many customers still do not understand. Today, we will take this opportunity to explain it. Hopefully, this will be helpful to those concerned. The current size codes for surface mount resistors are 0805 and 1206, with a gradual trend towards 0603. 0402 and 0201 packages are commonly used in high-integration products, which also places higher demands on SMT process technology. A common tolerance is J. In addition, it is recommended that users select and purchase each resistor, capacitor, and inductor according to the application of the component. If several types of surface mount components are encountered, it is advisable to purchase more, but due to the small size of surface mount resistors, storage and organization pose significant challenges for engineers. Of course, we also suggest that engineers purchase small boxes for storing components when purchasing surface mount components, but this is not always necessary. It should be noted that because these small boxes are not airtight, components stored in humid environments for extended periods may oxidize at the solder joints, causing poor solder joints. Purchasing a surface mount resistor sample book can avoid the above problems and allows for the purchase of a full range of resistors, but this is more costly and the quantity of each type may be limited.

Some key points on the use of surface mount resistors?

Surface mount resistors, also known as chip resistors, are a type of metal-glass glaze resistor. They are made by mixing metal powder and glass glaze powder and using screen printing to print them onto a substrate. They are particularly useful for their moisture and high-temperature resistance, and low temperature coefficient. They significantly save circuit space and cost, allowing for more refined designs. Below are some key points on the use of surface mount resistors.

What are the advantages of SMD resistors?

What are the advantages of surface mount resistors? We have briefly introduced this before, but found that many customers still don't understand. Today, we will take this opportunity to explain it. Hopefully, this will be helpful to those concerned. Surface mount resistors have the advantages of small size, light weight, strong shock resistance, strong anti-interference ability, and good high-frequency characteristics. In fact, the high reliability ruthenium series glass uranium material of its resistor body is made by high-temperature sintering, and has the characteristics of small size, light weight, high precision, low temperature drift, good stability, and good high-frequency performance. It has been widely used in computer peripherals and power supplies, home appliances, lamps and lanterns, battery packs, and power supplies. Secondly, it is also called a resistor, and in daily life it is generally directly called a resistor. A surface mount resistor is a current-limiting component. It means that after the resistor is connected to the product circuit, the resistance value of the resistor is fixed. It generally has two pins. Of course, you also need to know that these two pins are used to limit the current size of the branch connected to it. Common types of this kind of surface mount resistor include pressure-sensitive, temperature-sensitive, light-sensitive, and humidity-sensitive, all of which are through-hole. Therefore, surface mount resistors are widely used in consumer electronics, computers, and telecommunications fields. It is understood that the growth of the through-hole resistor market is driven by increased resistor technology advancements and the development of high-performance resistors.

Surface Mount Resistor Manufacturer: Some basic overviews of electrolytic capacitors?

Surface Mount Resistor Manufacturer: The development prospect of the electrolytic capacitor industry is very good, because it brings many benefits to enterprises when used, so it is deeply loved by customers. In order to let everyone understand more, we will now talk about some small knowledge points related to heavy rails, hoping to help more people. Surface Mount Resistor Manufacturer: Nowadays, many people still don't understand some basic information about electrolytic capacitors, so as a manufacturer, it is also necessary for us to briefly explain. In fact, an electrolytic capacitor is actually a capacitor. The metal foil is the positive electrode (aluminum or tantalum). When used, it naturally approaches the positive electrode. The metal oxide film (aluminum oxide or tantalum pentoxide) is the dielectric. The cathode is composed of conductive materials, electrolytes (electrolytes can be liquid or solid), and other materials. Surface Mount Resistor Manufacturer: Of course, this is mainly because the electrolyte is the main part of the cathode, so the electrolytic capacitor is named. At the same time, the positive and negative electrodes of the electrolytic capacitor cannot be connected incorrectly. Its aluminum electrolytic capacitors can be divided into four categories: lead-type aluminum electrolytic capacitors; horn-type aluminum electrolytic capacitors; bolt-type aluminum electrolytic capacitors; solid aluminum electrolytic capacitors. There are many advantages when used. For example, 1. The capacitance per unit volume is very large, dozens to hundreds of times larger than other types of capacitors.

What are the advantages of electrolytic capacitors?

Electrolytic capacitors are a common product in life, but most people don't know much about them. Today, we will mainly introduce some relevant information about it. If you are interested in this issue, let's take a look together, hoping that you will not feel unfamiliar when you see it in the future. Electrolytic capacitors are a very common product, and its application range is very wide. When using this product, we need to know that the electrolytic capacitor has a small volume, because the tantalum capacitor uses tantalum powder with very fine particles, and the dielectric constant ε of the tantalum oxide film is 17 times higher than that of the aluminum oxide film, so the unit volume capacitance of the tantalum capacitor is larger. In addition, there are some important points. That is, it can be used in a wider humidity range. Tantalum electrolytic capacitors can generally work normally at temperatures from -50℃ to 100℃. Although aluminum electrolytic capacitors can also work in this range, their electrical performance is far inferior to tantalum electrolytic capacitors. In addition, it has high edge resistance and low leakage current. The tantalum oxide film dielectric in electrolytic capacitors is not only corrosion-resistant but also maintains good performance after long-term operation. In addition, in fact, when the working frequency of the electrolytic capacitor is high, the impedance frequency characteristics are good.
