HW Chapter 22

Explain the role of dielectric material in determining the characteristics and applications of a capacitor.

Capacitors are used in signal conditioning circuits to create low pass, high pass, or ___ filters.

What is the significance of the self-resonant frequency (SRF) in capacitors, especially for high-frequency applications?

The unit of capacitance is the ___.

Which type of capacitor is most suitable for high voltage circuits?

• Film-based capacitors

• Ceramic capacitors

• Mica capacitors

• Polymer capacitors

Discuss the differences between polarised and non-polarised capacitors and their implications in circuit design.

What is the primary disadvantage of using aluminium capacitors in high-temperature applications?

• They dry out, increasing leakage and changing capacitance value

• They have a low self-resonant frequency

• They are more expensive than tantalum capacitors

• They are not suitable for RF applications
