Fixed inductors are electrical components, which are mainly used for impedance matching, circuit tuning and energy storage.  ELJ-PB220KF is an example of a fixed inductor. Its application field and working principle will be introduced in this article.

Application Field

The ELJ-PB220KF is usually used for mobile phones, personal digital assistant (PDA) devices, personal audio equipment, scanners and other electronic devices. With its small size, high performance and wide temperature range, it is the ideal choice for the above-mentioned electronic products. In addition, by virtue of its reliable quality and competitive price, it is becoming increasingly popular in the design of electronic equipment.

Working Principle

Fixed inductors, such as the ELJ-PB220KF, typically consists of an inductor body made of a conductive material, usually copper, and a conductive core which is wound around the body. When an AC voltage is applied to the inductor, a changing magnetic field is generated in the core which then induces a voltage in the inductor body. This induced voltage causes more current to flow through the inductor, creating a magnetic field around the core. This interaction between the current flow and magnetic field is what produces inductance.

In the case of the ELJ-PB220KF, the body is made of a magnetic material which provides an additional level of inductance. The magnetic material helps to “boost” the inductance of the core, allowing the inductor to store more energy than a standard fixed inductor. This additional energy storage capability makes the ELJ-PB220KF ideal for use in a wide range of applications where high energy storage is required.

The ELJ-PB220KF is also able to operate over a wide temperature range, thanks to its special construction. A special coating is applied to the core which helps it to withstand temperatures ranging from -40°C to 125°C. This temperature range is wider than most other types of fixed inductors, making it suitable for applications that require operation in extreme temperature environments.

Overall, the ELJ-PB220KF is a high-performing fixed inductor that is perfect for use in mobile phones, PDAs, personal audio equipment, scanners and other electronic devices. Thanks to its wide temperature range and energy storage capability, it is a reliable and cost-effective option for many electronic applications.
