6 FAQs about [What are the performance requirements for capacitors ]

Why should you choose a capacitor?

How do I choose a capacitor?

Depending on what you are trying to accomplish, the amount and type of capacitance can vary. The first objective in selecting input capacitors is to reduce the ripple voltage amplitude seen at the input of the module. This reduces the rms ripple current to a level which can be handled by bulk capacitors.

What determines the amount of capacitance required?

The electrical performance requirements of your design play a big part in determining the amount of capacitance required. The transient requirements of your system are very important. The load transient amplitude, voltage deviation requirements, and capacitor impedance each affects capacitor selection.

What is capacitor fundamentals?

Welcome to the Capacitor Fundamentals Series, where we teach you about the ins and outs of chips capacitors – their properties, product classifications, test standards, and use cases – in order to help you make informed decisions about the right capacitors for your specific applications.

What parameters should be included in the selection of output capacitors?

The most important parameters are the magnitude of the load transient (ΔI) and the distributed bus impedance to the load. The selection of the output capacitors is determined by the allowable peak voltage deviation (ΔV). This limit should reflect the actual requirements, and should not be specified lower than needed.

How to select input capacitors?

The first objective in selecting input capacitors is to reduce the ripple voltage amplitude seen at the input of the module. This reduces the rms ripple current to a level which can be handled by bulk capacitors. Ceramic capacitors placed right at the input of the regulator reduce ripple voltage amplitude.
