Capacitors

There are more types of aluminum electrolytic capacitors construction and termination styles: SMDs (V-chip) for surface mounting on printed circuit boards or substrates Radial lead terminals (single ended) for vertical mounting on printed circuit boards Axial lead terminals for horizontal through hole mounting on printed circuit boards Radial pin terminals (snap-in) for power applications Press-fit […]

Panasonic, one of supplier of all aluminum and tantalum polymer capacitor technologies provide comparison of its technologies as follows: OS-CON is a TCNQ salt electrolyte Hybrid combine wet and polymer electrolytes SP-Cap is a solid polymer chip capacitor POSCAP is a tantalum polymer capacitor The following chart is demonstrating lifetime with temperature comparison of wet

C 3.2 CONCEPTS AND MEASUREMENTS C 3.2.1 The CV product The product CR x VR is called the CV product and is a measure of the charge quantity. CR is expressed in µF and VR in volt. The product has the quantity µAs or µC (microCoulomb). C 3.2.2 Leakage current / DC Leakage (DCL) The

The basic idea of electrolytic capacitor types is to maximize surface area of electrodes and thus increase its capacitance value and capacitance density. Fine pores, cavities created on the electrode (anode) surface are then covered by a dielectric – usually insulator/semiconducting metal oxides. Electrolyte in a liquid/wet, gel or solid form is used as a

Silicon based capacitors are typically single MIM (metal-insulator-metal) or a multiple MIM structure capacitors build by semiconductor technologies. Silicon dielectrics are either silicon dioxide (MIS) or silicon nitride (MOS) insulating layers, however semiconductor manufacturing techniques such as atomic layer deposition (ALD) can be used to form other dielectric materials on top of silicon substrate. High

C 2.12 OTHER INORGANIC DIELECTRICS C 2.12.1 Class 3 ceramics The headlined type of ceramic capacitor are also called barrier layer capacitor. It consists of sintered granules of titanium oxides with semiconductor properties. On the surface of every granule there is created a capacitive barrier layer zone. The sum of all small capacitance elements gives
