SMD resistor, from now on, it will be a variety of electronic equipment indispensable element. With the continuous development of technology, the future application scenarios of SMD resistor will be expanded. We can see applications in smartphones, computers, smart homes, cars, medical devices and more.

A Rogowski coil is an inductive component that consists of a coil of thin wire wound around a magnetic core in the axial direction. When current flows through the Rogowski coil, it creates a magnetic field in the core, thereby producing an inductance. The Rogowski coil is used in electronic circuits such as oscillators, filters, and amplifiers, and is typically used in high-frequency circuits. In industrial settings, it is widely used in wireless communications, high-frequency induction heating, and power switches.

The standardized structure of copper terminal suitable for welding connection of aluminum wire mainly includes the following characteristics: (1) Terminal substrate: CuZn37 brass is recommended.

Cage terminal has the characteristics of high shock resistance, short wiring time, coupled with its heat resistance, corrosion resistance, is widely used in the field of electrical connection in the world. However, there are also some problems in the actual use of cage spring terminal, terminal burning failure often occurs, the main phenomenon is terminal burning, melting and so on.

Common Mode Choke, also known as common mode inductor, is wound symmetrically on a closed magnetic ring with the same turns in opposite directions. It is often used to filter common-mode electromagnetic interference, suppress the electromagnetic wave produced by high-speed signal lines to emit radiation, and improve the EMC of the system. In practical application, common mode inductance is generally added to the differential signal line.

A Rogowski coil, also known as a current measuring coil or differential current sensor, is a circular coil uniformly wound around a non-ferromagnetic material. The output signal is the derivative of the current with respect to time.

Toroildal inductors have the following functions: 1. Play a filtering role in AC circuit; 2. Can also play a vibration effect; 3. Dc circuit can play the role of frequency conversion; 4. It can also play the role of coupling and coupling.

Toroidal inductor (inductor coil) is an electromagnetic induction component wound with insulated wire, and is one of the commonly used components in electronic circuits.

What are the similarities and differences of voltage and current transformers? The current transformer is called CT and the voltage transformer is called PT. What they have in common is that they work on the principle of electromagnetic induction, which is used to monitor the electrical circuit: the current of the electrical circuit is monitored through CT, which is the current source of secondary instrument and protection

​The ring indicates the number of primary and secondary windings of the voltage transformer. One primary winding is removed, and the rest are all secondary windings.
