Dear customer, as you know, Suntan is a manufacturer of electronic components. One kind of our hot products is Plastic Film Capacitors. At present, we are glad to announce a good news to all of you: we would offer dv/dt (Change in Voltage divided by Change in Time, usually expressed in Volts per uSec.) from now on!

e.g. Metallized Polyester Film Capacitor TS02
TS02 1uF 250V +/-10% P:22.5mm bulk RoHS dv/dt:8V/us
TS02 1uF 400V +/-10% P:22.5mm bulk RoHS dv/dt:10V/us
TS02 1uF 630V +/-10% P:22.5mm bulk RoHS dv/dt:12V/us

If you have demand in Film Capacitor with dv/dt, welcome to send us your inquiry to our company email sales@capacitors.com.hk. For more product information, also freely refer to our catalogue of Film Capacitors: http://www.suntan.com.hk/pdf/catalogs/Suntan-Plastic-Film-Capacitors.pdf 

In these devices, polystyrene film is used as the dielectric. This type of capacitor is not for use in high frequency circuits, because they are constructed like a coil inside. They are used well in filter circuits or timing circuits which run at several hundred KHz or less.

The component shown on the left has a red color due to the copper leaf used for the electrode. The silver color is due to the use of aluminum foil as the electrode.

• The device on the left has a height of 10 mm, is 5 mm thick, and is rated 100pF.
• The device in the middle has a height of 10 mm, 5.7 mm thickness, and is rated 1000pF.
• The device on the right has a height of 24 mm, is 10 mm thick, and is rated 10000pF.
• These devices have no polarity.

In an electronic circuit, a capacitor is shown like this:

When you connect a capacitor to a battery, here's what happens:

• The plate on the capacitor that attaches to the negative terminal of the battery accepts electrons that the battery is producing.
• The plate on the capacitor that attaches to the positive terminal of the battery loses electrons to the battery.

Once it's charged, the capacitor has the same voltage as the battery (1.5 volts on the battery means 1.5 volts on the capacitor). For a small capacitor, the capacity is small. But large capacitors can hold quite a bit of charge. You can find capacitors as big as soda cans that hold enough charge to light a flashlight bulb for a minute or more.

Even nature shows the capacitor at work in the form of lightning. One plate is the cloud, the other plate is the ground and the lightning is the charge releasing between these two "plates." Obviously, in a capacitor that large, you can hold a huge amount of charge!

Let's say you hook up a capacitor like this:

Here you have a battery, a light bulb and a capacitor. If the capacitor is pretty big, what you will notice is that, when you connect the battery, the light bulb will light up as current flows from the battery to the capacitor to charge it up. The bulb will get progressively dimmer and finally go out once the capacitor reaches its capacity. If you then remove the battery and replace it with a wire, current will flow from one plate of the capacitor to the other. The bulb will light initially and then dim as the capacitor discharges, until it is completely out.

In the next section, we'll learn more about capacitance and take a detailed look at the different ways that capacitors are used.
