AI Customer ServiceHow to distinguish the positive and negative poles of electrolytic capacitors? First of all, let''s take a look at how to distinguish the positive and negative poles of conventional electrolytic
AI Customer ServiceAluminum electrolytic capacitors tend to be readily available, and with high voltage values (on the order of 700 V). These polarized capacitors usually have a wide tolerance (± 20%), tend to exhibit large leakage currents
AI Customer ServiceThe electrode attached to the aluminium sheet is the positive or anode and the electrode attached to the electrolyte is the negative. What causes this polarization in capactors? From the topic
AI Customer ServiceDistinguishing the polarity of surface-mount aluminum electrolytic capacitors It is critical to distinguish the positive and negative terminals when using bolt-type electrolytic
AI Customer ServiceWhen the electrolytic capacitors are polarized, the voltage or potential on the positive terminal is greater that of the negative one, allowing charge to flow freely throughout
AI Customer ServiceElectrolytic capacitors consist of two electrodes (anode and cathode), a film oxide layer acting as a dielectric and an electrolyte. The electrolyte brings the negative potential of
AI Customer ServiceAluminum electrolytic capacitor polarity identification. For aluminum electrolytic capacitors, the polarity is marked by: 1. The negative electrode of the aluminum electrolytic
AI Customer ServiceIt is critical to distinguish the positive and negative terminals when using bolt-type electrolytic capacitors, as reversing them can be very dangerous. First, check the marking
AI Customer ServiceNon-polarized capacitors do not have a positive or negative terminal and can be connected to a circuit in any polarity. Polarized Capacitors: Electrolytic and Tantalum

AI Customer ServiceThe positive and negative foils are wound together to form the core of the capacitor, which is then placed in an aluminum case for packaging. aluminum electrolytic capacitors have polarity, and reversing the polarity can
AI Customer ServiceGenerally (not always, due to manufacturing defects) the short lead is the cathode, negative; while the long lead is the anode, positive. When looking at the can, the lead
AI Customer ServiceBolt-type aluminum electrolytic capacitors have clear positive and negative grade marks on the bushing, and the positive pole is represented by "+" and the negative pole
AI Customer ServiceAluminum caps can be marked in a number of different ways. Radial, through-hole cans will commonly have a line down the negative side of the body, with the negative lead
AI Customer ServiceAluminum caps can be marked in a number of different ways. Radial, through-hole cans will commonly have a line down the negative side of the body, with the negative lead being shorter as well. Radial, surface mount
AI Customer ServiceAluminum electrolytic capacitors tend to be readily available, and with high voltage values (on the order of 700 V). These polarized capacitors usually have a wide
AI Customer ServiceBolt-type aluminum electrolytic capacitors have clear positive and negative grade marks on the bushing, and the positive pole is represented by "+" and the negative pole is represented by "-". Most bolt capacitors will be marked with "+" and "-" beside the terminals on the cover
Solder aluminum electrolytic capacitors are also called horn capacitors. Now all manufacturers choose the ones that have positive and negative poles, that is, they are marked with "-" for negative poles. Horn capacitors are easier to distinguish. In the revised version, many of them are marked "embossed" on the negative side.
Chip aluminum electrolytic capacitors are usually called SMD aluminum electrolytic capacitors. The bottom of the aluminum shell is printed with voltage, positive and negative poles, etc., usually half of the black is the negative pole. Many people ask why it is printed on the bottom. Because it has no casing. 3.
Normally, the negative terminal of and aluminum electrolytic capacitor is "marked". The "rectangles" shown on the datasheet can be considered as minus signs. By clicking “Post Your Answer”, you agree to our terms of service and acknowledge you have read our privacy policy.
Horn capacitors are easier to distinguish. In the revised version, many of them are marked "embossed" on the negative side. Of course, many manufacturers will directly print the signs of-and + on the positive and negative terminals. 2. Discrimination of positive and negative poles of chip aluminum electrolytic capacitors
Inside an aluminum electrolytic capacitor. (Image: Wikimedia / Elcap.) The electrochemical action produces a thin oxide film on the aluminum anode. The anode and apparent cathode are etched to increase the plate area. The thin oxide layer serves as the dielectric. The paper separator (spacer) holds the liquid electrolyte.
