Fixed inductors are extremely versatile components that are used in a variety of electrical or electronic circuit applications, ranging from controlling the flow of current to providing power supply filtering and decoupling. The PL9516T is an example of a series of fixed inductors developed by Pulse Electronics Corporation to meet a wide range of current-handling needs. It is designed for both high current saturation and low DC resistivity.

The PL9516T utilizes high permeability metal alloy core materials which can be further enhanced with the addition of an internal air gap in order to maximize inductance and minimize DC resistivity. This feature allows for a low-profile and cost-effective inductor solution with the capability to handle high levels of output current in a much smaller footprint than less-efficient components. The inductor also has other features, such as a higher inductance at lower frequencies than other inductors in the series. The combination of features allows for applications in high-end audio products, medical devices, and other products that require a small-size, high-performance inductor solution.

The core of the PL9516T is constructed using a combination of high-permability metal alloy core materials and is enclosed in a non-magnetic geometry. This produces a form of inductance that is highly efficient and extremely reliable. The design of the internal core geometry also minimizes DC resistivity and helps maintain good saturation performance, even at high frequencies. Additionally, a unique internal air gap feature further optimizes the inductance achievable from the core design.

The primary application field of the PL9516T is in high-current saturation applications and filtration circuits. It is particularly useful in a variety of medical device applications, such as medical electrodes, hearing aids, and artificial heart pacemakers. The inductor is also well suited for high-end audio components, including high-end headphones, studio monitors, and power amplifiers. It has also been found to be highly effective for automotive applications, offering excellent immunity and emissions filtering.

The working principle of the PL9516T inductor is based on the fact that when current flows through a coil of wire, a magnetic field is produced. This magnetic field induces a voltage which opposes the original current and causes the current to be reduced. The inductors of the PL9516T series are particularly optimized for the high current saturation performance required for most applications, allowing for a much more efficient solution than other types of inductors.

In conclusion, the PL9516T is an example of a series of fixed inductors developed by Pulse Electronics Corporation that provide excellent current-handling capabilities. With its high permeability metal alloy core materials, an internal air gap for maximum inductance and minimum DC resistivity, and a variety of features, this inductor is highly suitable for a range of applications, from medical to automotive. It also offers the benefit of having a working principle that is based on the fact that magnetic fields can be induced by the current flow, allowing for high current saturation performance.
