HV Ceramic Capacitor – What Is It?

Capacitors come in a variety of shapes and sizes and provide the power source of many electronic products. Ceramic capacitors (aka polyester, polystyrene, or polyimide capacitors) are a great choice for high-voltage power electronics, such as those found in computers. They can tolerate very high voltage levels, high currents, and even rapid temperature fluctuations without fail. Because they have a positive and negative charge characteristic, they can be placed in circuits that require a combination of these properties.

HV Ceramic Capacitor

For instance, if you wanted to power an MP3 player or your DVD player at high frequencies, but not to support heavy bass, then you should consider using an HV ceramic capacitor. An HV (High Voltage) capacitor is designed to cover the DC power supplied to the device, but will only accept a lower level of current high voltage ceramic capacitors. As a result, when the input signal gets to the capacitor, it can only handle low-frequency power levels. On the other hand, when you send a low-frequency signal to a high-frequency amp, the capacitor will amplify the signal and can deliver super-high frequencies. This is why the capacitor is often added to high-frequency circuits such as guitar amps and bass amps.

Final Words

Some people might be concerned about using an HV ceramic capacitor in their product, because of their inexperience in soldering. This is simply not the case; in fact, most professional solderers are familiar with the ins and outs of this type of capacitor. This makes the use of the high voltage ceramic capacitors an easy job for most experienced welder. If you want to use a capacitor of this type, you should ensure that the connection between the power source and the capacitor is made by an appropriately-sized conductor. Once you have installed the capacitor, test the connection to make sure that it works properly.
