What factors should you consider when using capacitors?
One important factor to consider when using capacitors is their polarity. Polarized capacitors have a positive and negative terminal, and must be connected to a circuit in the correct polarity. If a polarized capacitor is connected in the wrong polarity, it can be damaged or even explode.
Do capacitors have a positive and negative polarity?
Capacitors, especially electrolytic ones, have a positive and negative terminal. It's crucial to connect them correctly to avoid damage. Incorrect polarity can lead to the capacitor overheating, leaking, or even exploding. The longer lead is usually positive. Always refer to the datasheet or circuit diagram for specific polarity markings.
How do you determine the polarity of a capacitor?
To determine the polarity of a capacitor, you can look for polarity markings on the capacitor itself. Here are some ways to determine the polarity of a capacitor: Look for polarity markings: Most polarized capacitors have polarity markings, such as a plus (+) and a minus (-) sign, to indicate the positive and negative terminals.
What are the symbols of a capacitor?
Capacitors may also have symbols or additional text that provide further information. Some of the most common symbols include: Polarity Symbols: For polarized capacitors, such as electrolytics, a negative sign (-) or a line next to the negative terminal indicates polarity.
What are the polarity markings on a capacitor?
Capacitors often have the following polarity markings: "+" And "-" signs: The most common polarity marking on capacitors is a plus (+) and a minus (-) sign, which indicate the positive and negative terminals of the capacitor, respectively. The positive terminal is usually longer than the negative terminal.
What is capacitor polarity?
Capacitor polarity is the designation of the positive and negative terminals of a capacitor. This is important because capacitors can only be connected to a circuit in the correct polarity. If a capacitor is connected in the wrong polarity, it can be damaged or even explode. There are two main types of capacitors: polarized and non-polarized.

The requirement for "low-ESR" capacitors normally arises in output filters of switching power supplies, where the frequency is relatively high (kHz to MHz). It''s less important in mains filters (including the input filter of a SMPS) where a large capacity electrolytic tends to have a proportionally small ESR so that 100Hz or 120Hz ripple is not greatly affected by the ESR.
