​Iron core inductors are vital components in electronic circuits, with their behavior influenced by various factors, including frequency. Examining the influence of frequency on the behavior of iron core inductors is essential for understanding their performance in different applications and frequency ranges.

I would like to share with you some thoughts on the future development trends of latching relays. As an electrical component widely used in the field of automation control, latching relays have made considerable progress and have been extensively validated in practical applications. So, what new directions can we expect latching relays to take in the future? Let's explore together.

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 audio transformer can realize voltage-converter conversion just like the power transformer, and can also realize audio signal coupling. There are four main functions of audio transformer:Output transformer: used in audio equipment and playback equipment, impedance conversion in the circuit.

Potential transformer or PT can have the same construction as any normal transformer. It has primary & secondary winding. The number of turns in primary windings is greater than the number of turns in the secondary winding because it is a step-down transformer.

In many electronic application scenarios, people will use various types of transformers, whether it is a high-frequency transformer or a low-frequency transformer, the manufacturing process is similar. Next, Zou Gong, a senior design engineer from Shenzhen Yingzhe Technology Co., Ltd., will introduce the general production process of transformers.

The high frequency transformer is the most important part of the switching power supply. The switching power supply generally uses a half-bridge power conversion circuit. When working, two switching transistors are turned on in turn to generate a 100kHz high-frequency pulse wave, and then the high-frequency transformer is used to step down and output low-voltage alternating current.
