Fixed Inductors have been used in a wide range of applications over the years, ranging from radio antenna filters to voltage regulation circuits. One particular example, the PF0581.393NLT, is an inductor from passive components manufacturer Pulse Electronics. This component is an advanced design for a high Current Loop Filter (CTF) inductor. In this article, we will explore its application field and working principle.

Application Field

The PF0581.393NLT exploits its loop filter structure to provide high current delivery, from 0.1A to 20.0A. It provides a stable, low-noise, and high-frequency performance with low EMI. Its design allows for operation in temperatures ranging from 40°C to +100°C. It is designed to tightly adhere to automotive thermal requirements to ensure reliable operation. It can be used in a wide range of automotive applications such as Hybrid Electric Vehicles (HEV), Electric Vehicles (EV), General Motors (GM), and NISSAN.

Working Principle

The PF0581.393NLT is a high-current loop filter inductor designed using a planar magnetic technology. It consists of a closed loop configuration of magnetically conducting traces arranged on a printed circuit board (PCB). The current flows through the circuits and generates a magnetic field through the Inductor core, creating an inductance force in the opposite direction of the current. This results in a steady current flow along the loop, allowing for a very precise and stable voltage output at the output end.

The resultant power dissipation improves the life of the inductor by providing a greater choice of active components. It also increases stability by reducing EMI levels. Its standard design allows for a high current capacity with a low profile, ideal for high-density boards. The inductance value is kept constant over a wide temperature range, which reduces any noise generated by a change in temperature.

Conclusion

The PF0581.393NLT is an advanced high-current loop filter inductor from Pulse Electronics. It exploits its structure to provide an extremely stable, low-noise, and high-frequency performance. This inductor can be used in a wide range of automotive applications, such as Hybrid Electric Vehicles (HEV), Electric Vehicles (EV), General Motors (GM), and NISSAN. The design features a closed loop configuration of magnetically conducting traces arranged on a printed circuit board (PCB) to generate an inductance force. The result is a nearly constant inductance value over a wide temperature range and overall improved efficiency.
