Does all Chip Capacitors have the Polarity Markings on them. If so how do you recognize the markings.?

Question

How do you identify the polarity + - markings on chip (SMD) Capacitors.

Answer 1

The bigger one corresponds to the +ve teriminal and the smaller one to the -ve terminal.Got it!

Answer 2

It would be nice if they all did, and I for one, believe they should, but unfortunately it will depend on the manufacturer..  Most will be labled, but some will not..

You can identify them with circuit off as long as you know the contact points..  Follow the closest negative or posisitve source on the board that connects to the capacitor and identify either contact point with the source you traced on the board..(Positive or Negative)

This should let you know the positive or negative polarity of the capacitor..

If by chance this is an AC circuit that the capacitor connects with, then of coarse the polarity should not matter..

Same is true if you are needing to know the markings before the chip is placed on a board...  Just know the SMDs position it will be placed and use the same technique based on the board's design..

Answer 4

Only electrolytic capacitors need to be marked for the positive connection; and they typically have a bar on the positive end.

Because most chip capacitors are used for A.C. bypass, they are typically NOT electrolytic, and therefore do not need to be polarized. Electrolytics are most often to regulate a D.C. voltage line, to kill any low-level A.C.; these are typically larger devices, even in SMD (chip) design, and have the space for the bar identifying the positive lead.
