Pros and Cons of Non Audio and Audio Capacitors
What Are Capacitors?
Capacitors, or condensers, could be defined as a electrical components which are useful for storing charge in a power field. In professional terms, this can be a device which simulates the functions of battery at micro level in a power circuit.
How Capacitors works?
In basic terms, the normal audio capacitor manufactures produces components which works on the concepts of potential difference. If you have difference in electrical potential of two conductors, the electric field develops. As a result of this, the positive charge deposits using one conductor, leaving negative charge on another. This causes it to be to store energy which is found in various ways in electrical & electronic circuits.
Kinds of Common Conductors
The commonly used capacitors are described here briefly along with pros & cons.
Metalized Film Capacitor
In Metalized Film Capacitor, thin metal film is employed as the high voltage capacitor by which current is passed.
Pros - They are smaller in size as thin film is employed instead of conducting plates.
Cons - Thin films reduces current carrying capacity to an extraordinary extend, thus limiting its capabilities.
Aluminium Electrolytic Capacitor
Bi-Polar Aluminium Electrolytic Capacitor Manufacturers produce capacitors with aluminum electrolyte to be able to improve efficiency.
Pros - Durable, stable electrical parameters, Lower ESR
Cons - Low Voltage & Limited transient, lower reverse voltage tolerance, can burst in extreme parameters
Non Polar Electrolytic Capacitor
None Polar Electrolytic Capacitor Suppliers often adds special chemical to improve performance of capacitors. However, they still suffer from certain major disadvantages.
Pros - Size is smaller, great for long term use, stable on voltage fluctuations
Cons - can't tolerate extreme voltage, current carrying capacity is limited, can explode upon excessive heating
Audio Capacitor is not a special category of division. Instead, it is really a commercial name for those capacitors which are useful for audio circuits. It's possible to fit any suitable capacitor as per the wants & purpose of circuit.
Film Capacitor is really a special key in which thin film is employed to displace solid conductor plates of traditional style capacitors. This makes size extremely portable & escalates the durability as well. However, certain drawbacks remain attached with it.
Pros - size is small, fit for micro size circuits, predictable & stable behavior in several cases
Cons - self hearting, overheating on high voltage, limited current carrying ability
In broad terms, electrolyte capacitor plays an essential role. That is used as the standard to test other capacitors. Also, it is basic level capacitor which is commonly found in labs for elementary experiments.
Pros - Large voltage carrying capacity, reliable results, stable behavior, affordable
Cons - Leakage in most cases, require care & maintenance, overheating on wrong polarization, failure on wrong use
Speaker Capacitor is more an application than being truly a specific type. So, no specific pros & cons could be talked about. However, they're limited in their action of current carrying. Applying excessive voltage can result in failure.
