Fixed Inductors

Fixed inductors are an essential part of the circuitry in many applications ranging from DC to RF circuits, with the inductors being mainly copper or ferrite wound devices. In both cases, the inductor behaves as a magnetic inductor, hence providing electrical isolation as well as inductive reactance. One such type of inductor is the PL9125NLT.

The PL9125NLT is a high-reliability, low-profile surface-mounted inductor suitable for high frequency applications. It has a very low profile at max 0.62mm and a compact size of 12.7x6.9x2.9mm. The glass encapsulated construction gives excellent soldering reliability and high humidity performance. It offers a wide inductance range, from 1uH to 47uH, suitable for many applications.

The PL9125NLT is suitable for various applications in communication systems, industrial machinery, information devices and consumer electronics.

In operation, a typical fixed inductor can act as a high impedance coil for frequencies from DC to a selected frequency. At this selected frequency, the inductor will start to reduce the signal level as the inductance of the coil reduces the current passing through it. This is known as impedance transformation, which enables the inductor to attenuate the signal frequency to an acceptable level and prevent it from entering other filter circuits.

In DC circuits, an inductor provides electrical isolation. When an inductor is placed in series with a DC circuit, the current flows through the inductor\'s coils in the same direction as it does in the DC circuit. This is because of the inductive reactance, which is exhibited by the inductor, and which provides the DC circuit with electrical isolation.

In AC circuits, inductors also provide electrical isolation. When an AC current is applied to an inductor, the inductor produces a magnetic field that opposes the flow of the AC current, giving rise to a resistance phenomenon known as the inductive reactance. This provides the AC circuit with electrical isolation and prevents the AC current from entering other circuits.

The PL9125NLT is particularly useful in RF applications, such as cellular base station systems, where its low profile and compact size are beneficial. Its inductance range can also be precisely adjusted for desired performance. In addition, its excellent soldering reliability helps ensure dependable performance in all types of applications.

The PL9125NLT is a reliable, low-profile inductor, suitable for a variety of high frequency applications. Its wide inductance range, accuracy, and excellent soldering reliability make it an ideal solution for many modern applications. Thanks to its high electrical isolation, it can also be used in DC and AC circuits, such as radio receivers and power supplies.
