Fixed inductors are electrical components which provide a fixed amount of inductance. The PA4301.393NLT is a fixed inductor specifically designed to provide high-power performance in a small, surface-mount package. This article will provide an overview of the PA4301.393NLT’s application field and working principle.

Application Field

The PA4301.393NLT is a SMD-type (Surface Mount Device) fixed inductor, meaning it is designed to be connected directly to the surface of a PCB (Printed Circuit Board). The device is constructed with a high-quality ferrite core and insulated winding to provide superior power performance in a small package.

The PA4301.393NLT is an ideal choice for applications requiring power conversion, DC/DC regulation, and power line filtering. It is optimized for applications with a wide operating temperature range, from -40°C to +125°C, ranging from 0.2 A to 8 A. The device also features a high self-resonant frequency of up to 30 MHz, enabling it to take advantage of high-frequency switching modes.

In addition, the PA4301.393NLT has a wide voltage range of up to 55 VDC and is extremely resistant to EMI and other environmental conditions. This makes it an ideal choice for use in high-power, high-reliability applications.

Working Principle

The PA4301.393NLT works on the principle of induction. When an alternating current is applied to its windings, an alternating magnetic field is generated within the core which induces a voltage in the circuit. This voltage is proportional to the rate of change of the current in the windings. If the current in the windings is increasing, then the voltage will be positive (increasing); if the current is decreasing, then the voltage will be negative (decreasing).

The amount of voltage induced by the PA4301.393NLT is proportional to its inductance. As the current in the windings increases, the inductance of the device increases as well, producing a larger voltage. The device can also be used as an inductor filter, where the inductance can be adjusted to filter out any unwanted frequencies in the signal.

Due to its high performance, the PA4301.393NLT is an ideal choice for use in high-power applications. It is highly resistant to environmental conditions such as EMI and has a wide operating temperature range of -40°C to +125°C. The device also has a high self-resonant frequency of up to 30 MHz, allowing it to take advantage of high-frequency switching modes.

In conclusion, the PA4301.393NLT is a fixed inductor designed for high-power applications and wide operating temperature ranges. It features a high-quality ferrite core and insulated winding and has a wide voltage range of up to 55 VDC, making it an ideal choice for applications requiring power conversion, DC/DC regulation, and power line filtering.
