Are RF capacitors a c0g/npo material?
For the dielectric, RF capacitors are almost always a Class I C0G/NPO material due to their very low loss. Even more important is the choice of the inner electrode material. Figure 2 shows a comparison of resistance between a 100mm wire made from nickel and the same wire made from copper.
What material is used for base metal electrode RF capacitors?
The graph shows that as frequency increases above 10MHz, the resistance of the nickel wire starts increasing dramatically while the resistance of the copper wire remains relatively flat.
