The circle point is positive! The square or big piece is negative! The usual circuit board is marked with +- signs on or near the two pads of the capacitor. The actual color of the circuit board is white, that is, the pin on
On a circuit board, capacitor markings are used to indicate the correct orientation for installing polarized capacitors, such as electrolytic capacitors, tantalum capacitors, and polymer capacitors. These capacitors have positive and negative terminals that must be correctly aligned with the PCB’s design to ensure they function as intended.
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.
Capacitors are essential components found on most circuit boards. They regulate voltage, smooth out power fluctuations, and store electrical charge. In this guide, we’ll cover everything from different capacitors to how to replace them, troubleshoot problems, and find faults.
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.
Capacitors are indispensable components in PCB (Printed Circuit Board) design, providing functionality from energy storage and noise filtering to voltage regulation. Whether you're designing a simple circuit or a complex multi-layer board, understanding the different types of capacitors and their applications is crucial.
