High current high frequency capacitors

If a high frequency signal is passing through a capacitor, does it

Usually it is DC, but in your case it will be low frequency AC plus high frequency AC. So you need a cap with low $ dC/dV $ or capacitance variation per unit of voltage variation. That includes C0G ceramics and most types of film caps like PPS, PP, etc. In your case, since mains voltage is involved, be sure to pick a capacitor rated for it.

6 FAQs about [High current high frequency capacitors]

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.

What is a high current feedthru capacitor?

High current feedthru capacitors are designed as a broadband EMI filter that is specially designed to have high current handling capability. These capacitors have a capacitance range up to 100,000pF and a current rating up to 2A.

What type of capacitors have a high stability?

These capacitors are usually ceramics, and some ceramic dielectrics like NP0/C0G have very high stability. Self-resonant frequency or ESL: These values might be specified on a design curve or provided directly in the datasheet. They could also be determined from an impedance curve.

Do you need discrete capacitors in a high frequency board?

If you need discrete capacitors in a very high frequency board, then you need to account for these values in your circuit model. These values are determined by the following factors: The result is that the above curve is not necessarily observed once the components are placed on a real PCB.

What is an equivalent circuit for a RF capacitor?

Equivalent Circuits for RF Capacitors The equivalent circuit for a capacitor is well-known, especially by high-speed digital designers working on PDN impedance engineering. The equivalent circuit for a capacitor is generally modeled as a simple series RLC circuit, which gives a minimum in the impedance curve for the capacitor.

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.
