What is Supercapacitor?
What are the components of a supercapacitor? Active components of the supercapacitor are electrodes and electrolytes, whereas passive components are others. In
Available in both commercial and automotive grades, these capacitors exhibit very low ESR and high Q along with high SRF making them ideal for applications ranging from 1 MHz to 50 GHz. Key characteristics of RF capacitors and why they're important for high-frequency applications.
RF capacitors have very high Q due to their low capacitance and very low ESR. Therefore, RF capacitors are often referred to as High Q capacitors. Since RF capacitors are often used for tuning and impedance matching applications, capacitance stability versus temperature is critical.
Knowing the four key characteristics of an RF capacitor, a definition can be provided. Definition: An RF capacitor is a capacitor that's "characteristics" are optimal at RF frequencies. Therefore, for RF capacitors, materials are chosen, and designs are optimized so that the capacitor's characteristics are optimal at higher frequencies.
KEMET's HiQ CBR RF Capacitor Series features a copper electrode BME (Base Metal Electrode) system that offers ultra-low ESR and High Q in the VHF, UHF, and microwave frequency bands. Low ESR allows for higher RF currents which are ideal for various applications.
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.
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. For this reason, copper is the material of choice for Base Metal Electrode RF capacitors. Figure 2 - Resistance of a 100mm wire made from copper and nickel.
