As the most used chip capacitor material, X7R and NPO have excellent applications in many industries, such as mobile phones, broadband networks, industrial equipment, etc. These two chip capacitor materials often complement each other and have their own advantages.
As the most used chip capacitor material, X7R and NPO have excellent applications in many industries, such as in hand.
Machines, broadband networks, industrial equipment, etc., these two chip capacitor materials often complement each other, each has its advantages. Below, Pingshang Technology
Suzhou chip capacitors will detail the difference between X7R and NPO.
First of all, in terms of price, NPO material is generally more expensive than X7R. For capacity, NPO material is very large
Restricted, the capacity is very small, even if the package size of the package is generally less than 0.1uF; and the X7R capacity is much larger, often
To reach 22uF or even higher. In addition, in terms of chip capacitor accuracy, NPO material has obvious advantages, generally can reach J file ± 5%
Above; while the X7R is a bit weaker, but it can also reach K10 ±10%. Finally, in terms of temperature characteristics and stability, although the two types of patch electricity
The normal working temperature of the material is between -55 ° C and -125 ° C, but in terms of stability, the capacity of the NPO material is basically not affected.
The effect of temperature and temperature is still quite advantageous; while the X7R material capacity changes by 15% and changes with time, each time
Approximately 1% ΔC in 10 years, which is a change in capacitance of 5%.
