Fixed inductors, also known as inductors, coils, chokes and reactors, are passive, two-terminal components that store energy in a magnetic field when current flows through them. They come in a variety of shapes, sizes, materials and properties, and are used to filter, couple, delay and condition signals in power electronic applications. One of these fixed inductors is the PL9318T series of shielded, surface-mount inductors, which is commonly used in power line and telecommunications applications.

The PL9318T series of inductors use ferrite cores that are wound with high-performing, low-loss materials. The packaging of the inductors prevents electromagnetic interference (EMI) by shielding the magnetic field generated by the core, so it does not disturb other circuits nearby. With their tiny, low-profile package, these inductors are ideal for use on portable or handheld devices. They also have a wide operating temperature range, making them suitable for use in harsh environments.

The working principle of a PL9318T inductor is simple. When current passes through the windings of the core, it produces a magnetic field around the inductor. The field can only be changed if either the current flowing through the inductor changes or the flux through it changes. This creates an electromotive force (EMF) around the core, which acts like a back voltage, or counter EMF, that opposes the voltage supplied to the inductor. As a result, the total voltage drop across it is lower than the applied voltage, and the current flowing through it is therefore reduced. This change in electrical energy is stored in the magnetic field surrounding the inductor, and dissipates over time and in proportion to the current flowing through it.

Due to their small size and high shielding capabilities, the PL9318T series of inductors is ideal for use in power line and telecommunication applications that require shielding from EMI. Also, their wide operating temperature range makes them suitable for applications in both light and/or harsh industrial environments. In addition, the PL9318T inductors can be easily integrated into existing systems, as they are compliant with existing RoHS and lead-free standards.

In short, the PL9318T series of shielded, surface-mount inductors is an excellent choice for use in power line and telecommunications applications. Their small size, low-profile package, wide operating temperature range, and high level of shielding from EMI makes them highly suitable and efficient for these applications.
