Fixed inductors are components that store electrical energy in the form of a magnetic field. The PA4309.474NLT is one such component, and is used in a variety of electronic applications. In this article, we will examine the PA4309.474NLT application field and working principle.

What is the PA4309.474NLT?

The PA4309.474NLT is a surface-mount fixed inductor. It has a high current rating of 3.8A and an inductance range of 47 to 462 nH. The product has a low DCR of 0.98 to 2.53 mΩ, making it an ideal device for various high power applications. Additionally, it is offered in both RoHS and lead-free packages.

Applications of the PA4309.474NLT

The PA4309.474NLT is used in various electronic applications, including power supplies, DC-DC converters, resonant converters, and system adapters. It is also commonly used in high frequency switching power supplies. This makes it an ideal choice for a range of applications that require high current levels and high efficiency.

In power supplies, this component is used to reduce power losses and improve system reliability. DC-DC converters also use the PA4309.474NLT for its low DCR and ability to handle high ripple currents. Furthermore, this device is used in system adapters to adjust the output voltage, and in resonant converters as a snubber inductor.

Working Principle of the PA4309.474NLT

The PA4309.474NLT uses a core-and-coil construction to store electrical energy in the form of a magnetic field. When the voltage across the component is increased, this magnetic field increases as well, causing an opposing force that “cushions” the voltage. On the other hand, when the voltage across the component decreases, the magnetic field dissipates, allowing the voltage to drop more quickly.

The inductor works by allowing a steady current to flow uninterrupted through the component, regardless of the changes in voltage across it. This current can be controlled by adjusting the flux density in the core. This allows for much better control over the component than if it were simply wired in series or parallel with the AC or DC source.

Additionally, the component’s core-and-coil construction also allows for a much higher magnetic flux density than a traditional coil. This allows the device to handle much higher current levels than a traditional coil, while also remaining relatively small in size.

Advantages of the PA4309.474NLT

The PA4309.474NLT has some key advantages over other inductors, including:

• High current rating — With a high current rating of 3.8A, the PA4309.474NLT is ideal for a variety of high power applications.
• High efficiency — The component’s low DC resistance and ability to handle high ripple currents make it an ideal choice for high efficiency applications.
• Small size — The component’s core-and-coil construction allows for a much higher magnetic flux density than a traditional coil, resulting in a much smaller overall size.

Conclusion

The PA4309.474NLT is a surface-mount fixed inductor with a current rating of 3.8A and an inductance of 47 to 462 nH. It is used in a variety of electronic applications, including power supplies, DC-DC converters, resonant converters, and system adapters.
