How Capacitors Work

Several capacitors, tiny cylindrical electrical components, are soldered to this motherboard. Peter Dazeley/Getty Images. In a way, a capacitor is a little like a battery. Although they work in completely different ways, capacitors and batteries both store electrical energy. If you have read How Batteries Work, then you know that a battery has two terminals. Inside the battery,

6 FAQs about [What are the high power RF capacitors ]

What is an RF capacitor?

Before we define what an RF capacitor is, we need to provide some background on RF. RF stands for "Radio Frequency" and refers to the oscillation rate of an AC voltage, current, or electromagnetic waves in an electronic device or medium. Today, almost all electronic devices use alternating voltages and currents, ranging from 50Hz to 100s of GHz.

What is a high frequency capacitor?

About High-Frequency Capacitors High-frequency capacitors are marketed as such due to their ability to retain ideal capacitive behavior up to very high frequencies. Capacitors will not exhibit ideal behavior up to the intended operating frequencies in RF systems, even if they are marketed as “high-frequency” or “RF” components.

Why do RF capacitors have high Q?

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.

Do RF capacitors exhibit ideal behavior?

Capacitors will not exhibit ideal behavior up to the intended operating frequencies in RF systems, even if they are marketed as “high-frequency” or “RF” components. First, it’s important to note that both the construction of the capacitor itself and the PCB will create the non-ideal behavior observed in these systems.

What is the lowest rated frequency for a high frequency capacitor?

First series resonance (FSR) and first parallel resonance (FPR): These are the lowest rated frequency value at which S11 and S21 are rated for the capacitor in question. Here are two excellent sets of high frequency capacitors that are ideal for applications in the GHz range:

What happens if a capacitor reaches a high frequency?

At low frequency, the impedance provided by the capacitor is dominant, and your capacitor will exhibit close to ideal behavior. At sufficiently high frequency, the ESL value takes over, and the impedance starts to appear inductive. This produces an effect known as self-resonance at just the right frequency.
