General information There are two main sources of radio interference: - devices, which due to their construction produce RF energy. These include generators for science, as well as oscillators, - devices, which produce a wide to rapid variations in electrical current intensity. These include devices with switching components, thyristors, triacs, Interference from source to receiver is spread in three ways: along conductors, by coupling and is spread mainly along the installed electrical conductors. In this range inductive and capacitative coupling also occurs between the conductors and...

Definitions Taken From Standards: Class X capacitors are suitable for applications where there is no danger of electrical shock in case of breakdown. Class X capacitors are divided into three subclasses peak voltages of the pulses to which they are exposed during operation in addition to the line voltage. Such impulses can be caused by lightning in overhead lines, switching operations in equipment which is shielded by Class Y capacitors are suitable for applications where the breakdown dangerous electric shock. Class Y capacitors are subdivided into the mechanical safety is supposed to rule...

Figure 4: feed through capacitor for symmetrical usage (non-coaxial) Rated frequency The rated frequency is the rated supply frequency for which the capacitor is designed, by which it is described and to which other rated values relate. Surge voltage A surge voltage is an a-periodic single voltage of a certain profile Figure 5a: single by-pass capacitor Figure 5b: delta by-pass capacitor Figure 5c: example for a by-pass Rated voltage The rated voltage is either the voltage at rated frequency or the operating direct current voltage which is allowed between the total temperature range between...

drop with frequency increase. By parallel with the interference source, interferences are more or less short circuited. A capacitor incorporated in-parallel with power source terminal, suppresses symmetrical interferences, and between a power conductor terminal and the casing or earth it suppresses asymmetrical interferences. Impedance theoretically drops linearly with frequency. Due to shield inductance its own resonant frequency. Above this frequency the capacitor is frequency is decidedly influenced Thus with two-terminal capacitors range is reduced. For four-terminal conductors has no...
