Fixed inductors are passive components that are designed to resist changes in current according to Ohm’s law. They consist of coils of wire wound around a ferromagnetic core, and usually are composed of enamel-coated wire. Fixed inductors are often used in circuits for filtering, tuning, storing energy and matching impedance.IR02BHR39K is one type of fixed inductor. It is encapsulated in a sealed package with leads to facilitate assembly into circuits.

The IR02BHR39K fixed inductor features a higher operating temperature range, 120°C instead of the usual 70°C that is commonly found in inductors. This helps to further enhance the quality of the inductor and make it even more reliable and durable. It also features an enhanced impedance over a wide range of frequencies which ensures maximum power efficiency while maintaining a low cost.

The primary application for the IR02BHR39K fixed inductor is in power conversion and switching applications. It is particularly well-suited to applications in power electronic systems such as uninterruptible power supplies and voltage controllers. It is also suitable for use in switching applications such as DC/DC converters and motor drives. Other applications include voltage-controlled oscillators, bias networks, and clock distribution.

The working principle of the IR02BHR39K fixed inductor is based on the behavior of an inductor when an electric current is passed through it. Magnetic flux is created by the current flowing through the inductor’s wire, which in turn creates a back-EMF, an opposing voltage generated by the inductor which opposes the applied voltage. This creates a phenomenon known as “inductance” which can be exploited for various power management applications.

When current is passed through the inductor, it creates a magnetic field around the inductor as well as an associated reluctance in the core. This reluctance is caused by the decrease in the flux passing through the core, as current is passing through the inductor. It is this reluctance that makes the inductor resistant to changes in current. The magnitude of the inductance is determined by the size of the inductor and the number of winding turns.

The IR02BHR39K fixed inductor is capable of supplying high current for long periods of time, even in harsh environments. With its higher operating temperature range of 120°C, it is suitable for use in a wide range of applications. Additionally, it has very low losses and maintains a high impedance over a wide frequency range.

In summary, the IR02BHR39K fixed inductor is a high quality and reliable component with a wide range of applications. It is well-suited to power electronic systems such as uninterruptible power supplies and voltage controllers, as well as to switching applications such as DC/DC converters and motor drives. Its working principle is based on the reluctance created by the decrease in flux passing through the core when current is passed through the inductor, creating a phenomenon known as “inductance”.
