Fixed inductors are passive electronic components with a designated inductance value, which are generally used to store energy in the form of a magnetic field. ELJ-EA220KF is one of the fixed inductors designed with lead-frame type with height of 0.9mm and a broad temperature range of -40°C to +85°C. This article will cover the ELJ-EA220KF\'s application field and working principle.

Application Field

The ELJ-EA220KF is categorized as a fixed inductor. It can be used in variety of applications, such as power supply filtering systems, home appliances, automotive solutions, portable electronic products, telecommunication equipment, computer peripherals, consumer electronics, and industrial equipment.

Power supply systems, for example, can benefit from the ELJ-EA220KF, because it is designed to provide superior loss characteristics within a wide frequency range. Moreover, the ELJ-EA220KF inductor is capable of suppressing high-frequency common-mode noise and preventing high-frequency noise due to ripple current.

Next, the ELJ-EA220KF can be used for filtering in automobile systems. Cars nowadays require extremely stable power supplies due to the sensitive nature of electronic components. The ELJ-EA220KF inductor is able to filter out electrical noise from the power supply system. This helps to maintain the electrical performance while also protecting the system electronics.

Besides, the ELJ-EA220KF inductor can be used in telecommunication equipment such as SIM cards and landlines. With the ELJ-EA220KF inductor, the circuit can be kept stable while also reducing the noise generated when transmitting signals.

Working Principle

An inductor is a passive two-terminal electronic component that stores energy in a magnetic field when current flows through it. The ELJ-EA220KF is a fixed inductor that can effectively reduce voltage peaks and reject noise from the power supply. It works by converting electrical energy into magnetic energy, and then storing that energy in the magnetic field.

When current flows through the ELJ-EA220KF, a magnetic field is generated around the component that stores the energy. The magnetic field does not dissipate immediately when the current flow is stopped, but rather, it slowly decreases over time, allowing the inductor to provide a steady stream of current to the load.

The main factor that determines the performance of the ELJ-EA220KF inductor is its inductance. The inductance of an inductor is measured in henries, and the larger the number, the greater its inductance. The ELJ-EA220KF inductor is rated at 22 microhenries.

The ELJ-EA220KF is capable of providing excellent loss characteristics across a wide operating temperature range, thanks to its low Profile Litz-wire construction. This in turn results in superior high frequency operation.

The ELJ-EA220KF also offers a variety of features to ensure reliable operation, including a long life-span, lead-frame structure, and low DCR. This makes the ELJ-EA220KF an ideal choice for use in a variety of applications.

Conclusion

The ELJ-EA220KF fixed inductor is an ideal choice for applications that require filtering, noise reduction, and power supply optimization. The component is designed to offer superior loss characteristics within a broad temperature range, while also offering low DCR and a long life-span. In addition, the ELJ-EA220KF is flexible enough to be used in a variety of applications, such as power supplies, automobiles, telecommunications, and consumer electronics.
