The tough offers with longer lead time are general phenomenon for tantalum capacitors in the whole electronic markets, well, Suntan wasn’t so lucky to escape from this situation, but just more lucky than other makers such as Kemet, Vishay, AVX , the general condition for this part is on production allocation but assumed to 1 – 2 times shorter in comparison after observed from the current production capacity and delivery status. Thus that might be the reason why so many of the customers rush to us to ask for alternatives currently, and after contact us deeply, we are delighted to welcome more new partners to join in us.

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.

Square wave signals used in digital circuits can have a comparatively high frequency component included.

This capacitor is used to bypass the high frequency to ground.

• In the photograph, the capacitance of the component on the left is displayed as 104. So, the capacitance is 10 x 104 pF = 0.1 µF. The thickness is 2 mm, the height is 3 mm, the width is 4 mm.
• The capacitor to the right has a capacitance of 103 (10 x 103 pF = 0.01 µF). The height is 4 mm, the diameter of the round part is 2 mm.
• These capacitors are not polarized. That is, they have no polarity.

These capacitors have the shape of a disk. Their capacitance is comparatively small.

• The capacitor on the left is a 100pF capacitor with a diameter of about 3 mm.
• The capacitor on the right side is printed with 103, so 10 x 103pF becomes 0.01 µF. The diameter of the disk is about 6 mm.
• Ceramic capacitors have no polarity.
• Ceramic capacitors should not be used for analog circuits, because they can distort the signal.

A 1-farad capacitor would typically be pretty big. It might be as big as a can of tuna or a 1-liter soda bottle, depending on the voltage it can handle. For this reason, capacitors are typically measured in microfarads (millionths of a farad).

To get some perspective on how big a farad is, think about this:

• A standard alkaline AA battery holds about 2.8 amp-hours.
• That means that a AA battery can produce 2.8 amps for an hour at 1.5 volts (about 4.2 watt-hours -- a AA battery can light a 4-watt bulb for a little more than an hour).
• Let's call it 1 volt to make the math easier. To store one AA battery's energy in a capacitor, you would need 3,600 * 2.8 = 10,080 farads to hold it, because an amp-hour is 3,600 amp-seconds.

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.
