What does the X5R shown on the SMD capacitor tray mean 10

x5r refers to the dielectric characteristics of the capacitor, which is the temperature coefficient of the dielectric of the ceramic capacitor where x= -55 5= +85 r= 15 Note: This 15% does not refer to the accuracy of the capacitor, but to say that the capacitance may change by 15 in the process of changing the capacitor in the temperature range of -55 to +85, I will give you a specific example You can understand it by looking at it, this is the introduction of a product in the ** of the enterprise, this product is what you call x5r

Representative materials, capacitors generally have four materials.

1:C0G This material has the best performance, stable and reliable capacitance, but the capacitance is relatively small, and it is suitable for high-frequency and small-capacity capacitors. Take 0402 as an example, from.

2: X7R This material has good performance and capacitance stability, but the capacitance is medium to low, which is suitable for high-frequency and medium-capacitance capacitors. Take 0402 as an example, from 220pf to 100nf

3: X5R This material capacity can be enlarged, the capacitance stability is okay, suitable for large-capacity capacitors, suitable for large-capacity capacitors. Take 0402 as an example, from 56nf 1uf

3: Y5V This material capacity can be enlarged, with a wide range of capacitance and poor stability, which is suitable for large-capacity capacitors. Take 0402 as an example, from.

In terms of performance, C0G > X7R > X5R > Y5V

Generally depending on what brand it is, X5R stands for temperature characteristics.

x5r refers to the dielectric characteristics of a capacitor.

It is said that the temperature coefficient of the dielectric of the ceramic capacitor where x= -55 5= +85 r= 15 Note: This 15% does not refer to the accuracy of the capacitor, but to the capacitance of the capacitor may change by 15 in the process of changing the temperature range from -55 to +85.

According to the analysis statistics, capacitors are mainly divided into the following 10 categories:

1. According to the structure, it is divided into three categories: fixed capacitors, variable capacitors and trimmer capacitors.

2. Classification by electrolyte: organic dielectric capacitors, inorganic dielectric capacitors, electrolytic capacitors, electrothermal capacitors and air dielectric capacitors, etc.

3. According to the use, it is divided into: high-frequency bypass, low-frequency bypass, filter acre pin, tuning, high-frequency coupling, low-frequency coupling, and small capacitors.

4. According to the different manufacturing materials, it can be divided into: porcelain dielectric capacitors, polyester capacitors, electrolytic capacitors, tantalum capacitors, and advanced polypropylene capacitors, etc.

5. High-frequency bypass: ceramic capacitors, mica capacitors, glass film capacitors, polyester capacitors, glass glaze capacitors.

6. Low-frequency bypass: paper dielectric capacitors, ceramic capacitors, aluminum electrolytic capacitors, polyester capacitors.

7. Filtering: aluminum electrolytic capacitors, paper dielectric capacitors, composite paper dielectric capacitors, liquid tantalum capacitors.

8. Tuning: ceramic capacitors, mica capacitors, glass film capacitors, polystyrene capacitors.

9. Xunyou low coupling: paper dielectric capacitors, ceramic capacitors, aluminum electrolytic capacitors, polyester capacitors, solid tantalum capacitors.

10. Small capacitors: metallized paper dielectric capacitors, ceramic capacitors, aluminum electrolytic capacitors, polystyrene capacitors, solid tantalum capacitors, glass glaze capacitors, metallized polyester capacitors, polypropylene capacitors, mica capacitors. <>
