Fixed inductors are widely used in the fields of power electronics, high power frequency conversion, photovoltaics, motor drive and other fields. Most of the components of electronic design engineering are basically not changing. The equivalent of inductors, capacitors and resistors are mainly used. In this article, we will focus on the application field and working principle of one kind of inductor-HKQ04025N1H-E.

The main purpose of the inductor HKQ04025N1H-E is to provide electrical under a certain frequency environment, and it has excellent performance in terms of current, high power applications, dc-dc buck/boost applications and EMI/EMC applications. It is suitable for the following applications:

• DC-DC Buck/Boost converters
• AC-DC switching converters
• DC-AC switching converters
• High Power LED Driver
• Point-of-Load DC/DC converters

The inductor HKQ04025N1H-E is designed into a toroidal shape and uses a ferrite material core to enhance the efficiency of the power inductor. It has a wide operating frequency range, a high saturation current, a good ripple current and an ultra-low profile height. The toroid design and the air-core construction eliminate the presence of magnetic material that causes the leakage flux which may affect the adjacent circuit. The HKQ04025N1H-E absolutely meets the requirements of high-frequency application due to its high inductance value and its low DCR.

The working principle of the HKQ04025N1H-E is simple. When current flows through the inductor coil, an electromagnetic field is generated. This field then generates a magnetic force which opposes the flow of current. This type of inductor can be used in AC circuits to filter voltages and suppress noise efficiently. Li
