Coupling capacitor is the basic type of capacitors. A capacitor is a storage device that is known for storing the charge. Its structure is very simple in design. Parallel plates that are present in a capacitor are separated by the dielectric. Hence this makes the capacitor capable to store charges. A capacitor is available in various forms. One of the forms of this capacitor is coupling capacitors. The purpose of this type of capacitors is that to couple the output of the signal in AC form … [Read more...]
SMD Capacitor Working principle, Polarity Types, and Identification
SMD capacitor is the capacitor designed with different technology. SMD sometimes referred to as SMT which means 'Surface Mounted Technology'. This technology is about manufacturing the capacitors with such ease so that bulk manufacturing becomes easier. In this technology the capacitor is designed without leads. This makes convenient in placing the printed circuit boards (PCBs). With the use of this technology, various types of capacitors namely Ceramic and Tantalum are designed. Among those … [Read more...]
Ceramic Capacitor Construction, Function, Code and Applications
Ceramic Capacitors are non-polarized and fixed value capacitors. In circuits where a small size of capacitor is required Ceramic capacitors comes into picture. These where intially developed in German as replacement for mica. Before 1920's due to insulating properties of mica it was used as a dielectric material in a capacitor. Later, as there was shortage for mica a paraelectric titanium oxide was used as a dielectric which formed the Ceramic Capacitor. The first Ceramic Capacitor was disc … [Read more...]
Paper Capacitor Construction, Working, Advantages and Disadvantages
Paper capacitors are among one of the basic types of capacitors. Generally, in a capacitor the conducting material is separated by the dielectric. Based on the variant that is utilized as dielectric different types of capacitors are formed. The construction of this capacitor is similar to that of other capacitors, for example, plastic capacitors. The only difference between the other capacitors and this capacitor is that the dielectric chosen is of paper type. What is a Paper Capacitor? A … [Read more...]
Capacitor Introduction, Working & Applications
Capacitors are the basic element of any circuit that requires the smoothening of signals. These elements are widely preferred for the blocking of the DC signals. Whenever a capacitor is supplied with the DC voltage the positive charge is settled at one side of the plate. The remaining negative charges are shifted at another plate. In this way, the charges have attained a state of stability. Hence the positive and the negative charges neutrally arranged on the plates. This is the reason when … [Read more...]
Film Capacitor, Introduction, Working, Types, and Uses
Film Capacitor is one of the most popular and widely used capacitors. These possess a difference in their properties of dielectric. In the modern type of film capacitor, there is the ‘direct electrical connection' establishment with the electrodes that are present on both the winding's. This keeps the path of the current to the electrode very short. This capacitor has various benefits like it has very low ESR(ohmic resistance) and ESL(Parasitic Inductance). This can be preferred in various AC … [Read more...]
