常见问题

What is the difference between input and output capacitors?

Input capacitors filter incoming AC/DC voltage and reduce electromagnetic interference, while output capacitors smooth the regulated DC output and handle load transients.

How do I select capacitors for a power circuit?

Consider voltage rating, capacitance, ESR, temperature range, and ripple current rating based on circuit requirements and operational environment.
