Longer Lead: In through-hole electrolytic capacitors, the negative terminal is often connected to the shorter lead, while the positive terminal connects to the longer lead. Datasheet Reference: Consult the capacitor’s datasheet for polarity information, especially when dealing with surface mount electrolytic capacitors.
Another way to identify the positive and the negative terminals of a capacitor is the length of the two leads. The longer lead is the positive terminal, while the shorter lead is the negative terminal. How To Identify the Value of the Capacitor?
Negative Marking: Typically denoted with a “-“ symbol or sometimes a black stripe. The negative terminal of the capacitor should align with this marking. In some cases, the negative pad may be shorter than the positive pad to ensure proper orientation. Capacitor Footprint:
You have to look for a minus sign, a large stripe, or both on one of the capacitor’s sides. The negative lead is closest to the minus sign or the stripe, while the unlabeled lead is the positive one. The length of the two leads. The longer lead is the positive terminal, while the shorter lead is the negative terminal.
Markings on the PCB: Positive Marking: Often represented by a “+” symbol, indicating where the positive terminal of the capacitor should be placed. Negative Marking: Typically denoted with a “-“ symbol or sometimes a black stripe. The negative terminal of the capacitor should align with this marking.
Before delving into identifying capacitor polarity, let’s grasp the concept of polarity itself. In electronics, polarity refers to the positive (+) and negative (-) terminals of a component, indicating the direction of current flow. Capacitors, like other electronic components, possess polarity, denoted by their positive and negative terminals.
