How Much Ripple Per Amp Capacitance Is Acceptable

Last Updated on January 3, 2024 by Paganoto

What is an acceptable ripple voltage? – Quora

For most applications 5% ripple in the output dc voltage is acceptable. Some of high precision applications may require 1–2% ripple.

Ripple Voltage – an overview | ScienceDirect Topics

Typical capacitors of the next value up from this, 6800 μF, have 85°C ripple current ratings from 2 to 4 A. The higher ratings are larger and more expensive.
