jb What is a Capacitor ?

A capacitor is a small device that can be charged up with electrical energy, store it and then release it. Just like a rechargeable battery. But unlike a battery, it does not use a chemical reaction and it can only hold a very small charge. A very large capacitor can only light up an LED for a few seconds. They come in many shapes and sizes and a few are shown below. The bigger the capacitor, the more charge it will hold. Capacitor is made from two metal plates or metal foils separated by an insulator called a Dielectric material.

The Dielectric materials can be made from Ceramic, Mica, Polypropylene, Polyester, Electrolytic, Tantalum and even air.

The larger capacitors look like tubes, this is because the metal foil plates are rolled up with an insulating dielectric material sandwiched in between.

The value of capacitance is determined by

1.The size of the plates,

2.The distance between them,

3.The type of dilectric material used.

jb Capacitors Car Audio Capacitor

Many car audio enthusiasts ask about the importance of car audio capacitors to their overall car audio performance. If you have a high powered system or your amplifier doesn't get enough power, probably you need a capacitor. Making sure you have a capacitor installed will prevent any damages to your amp and other audio components.

What is the main role of a car audio capacitor?

Unlike automobile batteries, the main function of an audio capacitor is to store energy. This stored power will be used on demand (when your amp needs it). This will ensure that your audio system is being used to its maximum capability.

How do I know that I need an audio capacitor?

The first thing you will notice is dimming lights. The light will get weaker each time a heavy bass note sounds. If you installed the right capacitor, your audio system would have received the right amount of power needed.

What type of a car audio capacitor should I buy?

Depending on your system, but generally speaking:

- For mid-level systems (1000 watts maximum), you need a 1 Farad capacitor.
- For 1000 - 2000 watt systems, you need to get 1.1 to 1.9 Farad capacitor.
- For 2000 - 3000 watt systems, you need 2 to 2.9 Farad capacitor.
- For high power (over 5000 watt) systems, you need 5+ Farad capacitor

jb tell you How to test a capacitor

key words: film capacitor. electrolytic capacitor

If you always purchase many kinds of film capacitors, or electrolytic capacitors, you should know how to test the capacitors.
1. Remove the suspected faulty capacitor from the unit. If it's a high powered capacitor, it will still hold a high charge. Discharge the capacitor by using a metal screwdriver with a handle that's insulated. Touch the metal end of the screwdriver to both metal terminals at the same time to discharge any power left in them.
2. Turn on the capacitor tester and make sure it's getting power. Plug in the tester probes according to the instructions on the meter. Set the selector to an OHM scale before testing the capacitor. Some meters will have an OHM setting pre-set for you.
3. Touch the leads together so that the meter will zero out by adjusting the wheel on the meter
4. Note where the meter points to before touching the wires to the capacitor. Then touch the terminals of the capacitor with the red probe, which will go on the left, and the black probe which will go on the right.
5. Watch the pointer on the meter. The needle should move away from the left side, or the infinity, and veer toward the right before returning to the infinity. It should move further to the right when the probes are reversed. This means the capacitor is good. If the needle goes all the way to the right side and doesn't return to the left, or infinity side, the capacitor is bad, or it has shorted out.
