The iron oxygen material is a magnesium or iron nickel alloy, which has a high conductivity and which can be the smallest of the electrical profiles produced between the electrons ' circuits under high resistance conditions. Iron oxygen material is usually used in high frequency (hf) conditions, as they are mainly electro-sensored at low frequency, resulting in minimal loss on line. In the case of high frequency, they are mainly subject to electrical resistance and change with frequency。
In practice, iron oxygen material is used as a high frequency decayer for radio frequency circuits. In practice, better iron oxygen is equivalent to electrical resistance and the combination of sensory, low-frequency electrical resistance is short-circuited and high-frequency electrical resistance becomes so high that all currents pass electrically. Iron oxygen is a consumption device where high-frequency energy is converted to thermal energy, as determined by his resistance properties。
Iron oxygen magnets are better hf filtered than normal electrons. Iron oxygen is electrically resistant at hf, which is equivalent to a low-quality factor electrical sensor, and can thus maintain high resistance within a fairly wide frequency range, thus increasing hf filter effectiveness。
In low band
Resistance consists of a sense of resistance, low frequency r is small, magnetic cores have a high magnetic conductivity, hence the amount of electrons, l plays a major role, and electromagnetic interference is inhibited by reflection; and, at this time, the loss of magnetic cores is smaller, and the entire device is a low-depletion, high-q properties electrical sense, which can easily cause vibration to increase in the low frequency range, sometimes after the use of iron oxygen。
In high frequency segment
Resistance consists of resistance components, which, as frequency increases, the magnetic conductivity of the magnetic core is reduced, resulting in the reduction of the sense of electrons and resistance elements, but at this time the loss of the magnetic core is increased, the resistance is increased, leading to an increase in total resistance, and when high frequency signals pass through iron oxygen, the electromagnetic interference is absorbed and converted to thermal energy consumption。
The iron oxygen inhibitor element is widely used on printed circuit boards, power lines and data lines. High frequency interference can be filtered by adding an iron oxygen inhibitor at the end of the power line on the board. Iron oxygen magnet rings or magnetic beads are designed to suppress signal lines, high frequency and peak interference on power lines and have the capacity to absorb electrostatic pulse interference。
The use of tablets of magnets or tablets of electrons is still mainly in practical applications. There is a need to use a bit of a sense in the resonance circuit. The use of tablets is the best option when there is a need to eliminate unwanted emi noise。
Application
Radio frequency (rf) and wireless communications, information technology equipment, radar detectors, automobile electrons, cellular phones, pagers, audio equipment, pdas (personal digital assistants), wireless remote control systems and low-pressure power supply modules。
Snippet magnetic beads: the clocks undergo electrical circuits, simulate filters between circuits and digital circuits, i/o input/output in-house connectors (e. G., serials, junctions, keyboards, mouse, long-distance telecommunications, local area networks), between radio frequency (rf) circuits and susceptible logical devices, filtering of high frequency conductive interference in electrical circuits, computers, printers, video recorders (vcrss), emi noise in television systems and mobile phones。
The units of the magnets are om, because the units of the magnets are labelled according to the resistance it produces at a certain frequency, which is also om. The datashet of magnets generally provides frequency and resistance characterizations, generally based on 100 mhz, for example, at 100 mhz. The frequency for which we are going to filter requires the selection of magnetic beads to resist as much as possible, usually 600 euros above。
The selection of magnetic beads requires attention to the flow of magnetic beads, which generally requires an 80 per cent reduction in treatment, and consideration of direct flow resistance to pressure-relief effects in power circuits。
