The power supply at the VDD pin should be clean as possible for a good DAC performance. This pin requires an appropriate bypass capacitor of about 0.1 μF (ceramic) to ground. An additional 10 μF capacitor (tantalum) in parallel is also recommended to further attenuate high frequency noise present in application boards. The supply voltage (VDD ...

There are a few different types of electrolytics, but they mostly use a very thin layer of oxide as the dielectric and a conducting semi-liquid electrolyte as one of the plate electrodes. These polarized capacitors are often used in coupling, ripple smoothing, DC blocking, bypassing, filtering and timing applications. Polystyrene Capacitors.

In the old days, when ceramic caps were harder to come by in large capacitances, most regulators relied on tantalum or aluminum electrolytic caps for output filters. These have a moderately high ESR. Accordingly, the regulators were designed to be stable with relatively high ESR output caps. Low ESR caps might not be stable in such …

Only, the tantalum reaction has much lower activation temperatures - temperatures that are easily and quickly achieved should opposite polarity or an overvoltage event punch a hole through the dielectric (tantalum pentoxide, much like aluminum oxide) and create a short. This is why you see tantalum capacitors voltage and current derated …

8 I am doing some research on the different kinds of capacitors. Here is my brief understanding of the use cases for each kind of capacitor: Aluminum Electrolytic: …

filter behaves. Tantalum Construction The tantalum capacitor utilizes an oxidized layer of the tantalum metal as the dielectric. Con-struction first involves the formation of an anode pel-let structure. Tantalum particles are pressed in a die cavity with a tantalum wire protruding out of the pel-let (Figure 2). At this point, the tantalum ...

I have to filter a power control circuit and as usual I am using lots of capacitors in parallel. Some of these capacitors are Tantalum or Aluminium Polymer types, with ripple current ratings of 3 amps or so... in normal operation the ripple current will be just fine, but when the battery is first attached to the circuit I expect that the capacitors will behave like a short …

Today we even have capacitors that have been specifically designed for high quality audio use (the so called "Audiophile " caps). Replacing aging, underperforming capacitors with modern high-performance audio grade types specially selected for each amp's type of circuitry, can easily take any vintage amp far beyond it's original sound ...

Two things can be consider for using Tantalum capacitors instead of ceramic capacitors: 1) Tantalum capacitors can sometimes be found with a very high capacitance (more than 470 uF) in a single reasonably sized component (EG 7.3x4.3 mm). This could possibly reduce assembly cost or allow an easier layout.

Tantalum - Polymer Capacitors. Tantalum polymer capacitors are a polarized capacitor type distinguished by their use of a conductive polymer anode material, instead of the manganese dioxide traditionally used for other dry tantalum devices. While their cost tends to be higher, they also generally exhibit better electrical performance compared ...

Here in this circuit the capacitors acts as a filter. Which opposes the AC signal to flow through or appear at the output terminal. The designer used various capacitors in order to filter the signal in order to get the desired DC level. Here the capacitors are used across regulator inoder to obtain stability.

hundred kHz with low losses. This type of capacitor competes directly with the solid tantalum type in high frequency filtering applications and has the advantage of a much broader range of available values. Solid tantalum electrolytic capacitors are generally limited to voltages of 50 V or less, with capacitance of 500 µF or less.

I replace all electrolytic coupling caps (aluminum or tantalum) with Panasonic HFQ units (if there's a DC voltage across them) or Panasonic Bi-Polar caps (if there isn't). I always try to use at least a 35V cap, space permitting. Similarly, I replace all power supply caps with Panasonic HFQs, again using larger voltage ratings when possible.

Basically it just needs to be polarized (and polarized capacitors have the unique property of exploding when the polarity is reversed except Tantalum Caps Charge and Discharge almost instantly while Electrolytic Caps don't which is why the exploding capacitor occurs with Tantalum Caps more often). Tantalum capacitors take up about 5% as much ...
