VIDEO ON THE TOPIC: A simple guide to electronic components.

Noise measures. Surge and ESD electro-static discharge refer to transient high voltage, and possibly a very dangerous noise under certain conditions. A Surge and ESD may cause malfunctions to the equipment or circuit when the level reaches a certain degree, and the level often experiences high voltage far exceeding the permissible range. In such cases, the affected component or equipment is broken in an instant. The diagram is a mapped image of surge voltage and its width. Surge and ESD are described below.

Lightning as natural phenomenon contains a very large amount of energy. A lightning surge can be grouped into direct lightning surges and induced lightning surges. Protection against a direct lightning surge is difficult, but protection against induced lightning is possible.

Induced lightning is a high voltage surge induced by a relatively long wire such as power line or communication cable that is nearby a lightning strike. It is presumed that the generation mechanism is an electric charge induced in a cable that is in proximity of an electric field discharged by a lightning strike, or a magnetic field generated by a lightning strike current generates an inductive electromotive force in the cable. As shown in the previous diagram, an induced lightning surge has a large amount of energy that can easily destroy electric or electronic components even though it is not as destructive as a direct lightning surge, thus requiring prevention measures.

This high voltage surge may cause a malfunction of an electronic circuit, and in some cases, lead to the destruction of a component. Load dump is a surge generated by cutting the battery connection off on an automobile. The most severe instance occurs when the battery connection is lost while the automotive engine is in operation and the alternator battery charging generator is charging the battery.

The magnitude of surge voltage is determined by the alternator rotation speed and magnetic field excitation strength at the moment of cut off.

Surge voltage exceeds V in some cases for a duration of several hundred milliseconds. Because this surge has such a large amount of energy, it can easily destroy an electronic component. Permissible load dump is specified by auto-makers and automotive equipment makers in the form of maximum voltage, line impedance, and duration time. ESD electrostatic discharge is a phenomenon where a charge is stored in a small floating capacity on a human body or substance then discharged to a nearby object, and is classified as one type of surge.

ESD duration time is short with little energy, but because it generates transient high voltage as high as several kilo volts, it can generate a malfunction of electronic circuits or damages electronic components.

For the evaluation and testing method of an ESD, a human model or machine model is generally used. And protection is possible by utilizing the components based on these assumptions. For the purpose of protection against a surge and ESD, use of a varistor or zener diode is the general choice. These components have a high electrical resistance when the terminal voltage is low, but the resistance suddenly becomes low when the voltage gets higher. By using this tendency, the component prevents a surge from entering the circuit by bypassing the current when a high voltage surge occurs in an electric circuit.

The diagram to the right illustrates how to protect a power supply circuit from induced lightning surge by using a varistor. Panasonic was the first manufacturer in the world that commercialized ceramic varistors with a superior ceramic material design and process technology backed by many achievements in device design and production engineering. This product provides excellent voltage non-linearity characteristics in parallel with those of zener diodes along with large current resistance characteristics not found in other products.

Chip varistor is a chip-shaped laminated varistor, and the basic structure is a laminated ceramic component similar to a laminated ceramic capacitor MLCC. Basic structure. Chip varistors are used in a wide variety of electronic equipment as general purpose ESD protection components. The minimized static capacitance is suited for using in a high-speed signal line. Basic Structure. Compared with the chip varistors described above, an ESD suppressor has a very small electrostatic capacitance and is a major difference in characteristics.

The voltage-current characteristics can accommodate an ESD in the range of several kilo-volts. A very small electrostatic capacitance 0. Before replacement, we should know what a zener diode is first. The voltage and current characteristics of a zener diode are shown below. A single zener diode provides voltage restriction effect only at the negative voltage side, but by using two diodes in an opposite series connection, bidirectional voltage restriction effect can be obtained, as is the case in a varistor.

For an advantage over a varistor, effective protection voltage can be set at a low level of several volts. However, for disadvantage, they require a large shape and more weight as well as a larger mounting surface area than a varistor. Although a bidirectional zener diode is available by connecting two diodes in a single package, it is still larger than the size of a varistor.

As described, surge protection by using zener diodes requires 3 components, but a single varistor can serve the same function, thereby achieving a substantial reduction of size, weight and mounting surface.

In the case of ESD prevention, replacing 0. The graph shown below is a comparison of resistance to ESD and surge current between 0. The graph shows that resistance to ESD and surge current improves by replacement with a chip varistor. The difference and features of each component are summarized in the table below. Application coverage for each ESD prevention component is summarized in the diagram below.

Maximum value of the commercial frequency sinusoidal wave voltage effective value allowing continuous application, or maximum value of DC voltage.

When a surge voltage is applied, the voltage value restricted by the varistor is called restricted voltage, and an individual catalog lists the maximum restricted voltage as maximum value. This value indicates the level of surge current resisted by the varistor.

OUR EXPERIENCE IN A NEW DIMENSION

In an embedded system it is often desirable to communicate with another device wirelessly. This wireless communication may be accomplished through optical communication or through radio-frequency RF communication. For many applications, the medium of choice is RF since it does not require line of sight. RF communications incorporate a transmitter and a receiver. They are of various types and ranges. Some can transmit up to feet. RF modules are widely used in electronic design owing to the difficulty of designing radio circuitry. Good electronic radio design is notoriously complex because of the sensitivity of radio circuits and the accuracy of components and layouts required to achieve operation on a specific frequency.

Фонтейн, которого он знал, был внимателен к мелочам и требовал самой полной информации. Он всегда поощрял сотрудников к анализу и прояснению всяческих нестыковок в каждодневных делах, какими бы незначительными они ни казались. И вот теперь он требует, чтобы они проигнорировали целый ряд очень странных совпадений. Очевидно, директор что-то скрывает, но Бринкерхоффу платили за то, чтобы он помогал, а не задавал вопросы.
