Founded in 1973, Samsung Electro-Mechanics has grown into a company that develops and manufactures core electronic components worldwide, including in Korea. The "motor" of Samsung Electro-Mechanics (Samsung Electro-Mechanics) uses the electric and mechanical machines of lightning in Chinese, and also uses the English Electro (electrical) and Mechanics (mechanical).

When Samsung Electro-Mechanics was established, based on the production of Audio/Video components, it laid a solid foundation for the independent technology of component products in the Republic of Korea. In the 1980s, the business field expanded to materials and computer components. The next generation of components, optical components and other promising new products.

Since the 21st century, based on core technologies such as materials, multi-layer film forming, and high-frequency circuit design, we have sought in-depth development of strategic technologies and synergistic effects of business. Focusing on this, we have concentrated on cultivating business such as chip components, camera modules, and communication modules. .

Samsung Electro-Mechanics will produce the world's best core products, continue to develop new products through technological convergence, expand the scope of its business portfolio, and advance the next generation of growth businesses to develop into a leading company in the electronic components industry.

SAMSUNG Samsung capacitor introduction

Introduction of capacitors:

Capacitors are generally represented by "c" plus numbers in the circuit (for example, c25 represents the capacitor numbered 25). Capacitors are made of two metal films that are close to each other, separated by insulating materials in the middle, and the size of the capacitor capacity indicates the size of the electric energy that can be stored. related.

Five parameters of Samsung capacitors:

1. SMD capacitor size

Metric： 0603 1005 1608 2012 3216 3225 4532 5750

Imperial： 0201 0402 0603 0805 1206 1210 1812 22202、

2. The material of the chip capacitor

Material Specifications of SMD Multilayer Capacitors

SMD capacitors currently use COG (NPO), X7R, Y5V, Z5U, and other different material specifications.

COG (NPO) material capacitor

COG (NPO) is one of the most commonly used monolithic ceramic capacitors with temperature compensation.

COG (NPO) capacitors are one of the most stable capacitors in terms of capacitance and dielectric loss. When the temperature is from -55℃ to +125℃, the capacity change is 0±30ppm/℃, the capacitance

NPO capacitors have different characteristics of capacitance and dielectric loss with frequency depending on the package form. Larger package size has better frequency characteristics than small package size.

NPO capacitors are suitable for tank capacitors in oscillators, resonators, and coupling capacitors in high frequency circuits

X7R material capacitor

X7R capacitors are called temperature-stable ceramic capacitors. When the temperature is from -55°C to +125°C, its capacity changes by 15%. It should be noted that the capacitor capacity at this time

The capacity of the X7R capacitor is different under different voltage and frequency conditions, and it also changes with time, about 1% ΔC every 10 years, showing a 10-year change

X7R capacitors are mainly used in less demanding industrial applications where the change in capacitance when the voltage changes is acceptable. Its main features are in the same

The capacity errors generally used are: K-level ±10%, M-level ±20%.

If you need K-class ±10%, M-class ±20% capacitors, then choose X7R material components.

Y5V material capacitor

The Y5V capacitor is a general-purpose capacitor with a certain temperature limit, and its capacity can vary from +22% to -82% in the range of -30°C to 85°C.

The high dielectric constant of Y5V allows the fabrication of capacitors up to 4.7µF in a small physical size.

Other technical indicators of Y5V capacitors are as follows: Operating temperature range -30℃ --- +85℃ Temperature characteristics +22% ---- -82% Dielectric loss Maximum 5% actual

3. SMD capacitor capacity

The basic unit of chip capacitors is PF, and the capacity is mainly represented by digital notation: generally three digits are used to indicate the capacity, the first two digits are significant figures, the first 100=10x 10 =10PF 222=22x10 =2200pf=2.2 nf 2R2=2.2PF 105=10X10 =1000000=1000NF=1UF

4. The accuracy of chip capacitors

The accuracy of the chip capacitor is also called the capacitance value error, which refers to the allowable gap between the rated capacitance value of the capacitor and the actual capacitance value. The general errors are: C=±0.25PF D=±0.5PF J=±5% K=±10% M=±20% Z=+80%-20% (Note: the accuracy code of each brand is different)

5. The voltage of the chip capacitor

Rated working voltage: The capacitor can work stably and reliably for a long time in the circuit, and the maximum DC voltage it can withstand is also called withstand voltage. For structure, medium.
