Fixed InductorsFixed inductors, also known as chokes, are passive components used to introduce electrical impedance into an electronic circuit. They can be made of a variety of materials and depending on their application come in a variety of shapes and sizes. One type of inductor, the PA4318.104NLT, is designed for suppressing power line noise between 50kHz and 1MHz. It is a small air-core inductor which can easily be fixed into a circuit without the need for soldering.As with other types of inductors, the PA4318.104NLT has a simple working principle. It is based on the mechanism of magnetic induction, which states that a changing magnetic field will create a current in an inductor due to the relative motion between the magnetizing force and the conductor. This phenomenon is exploited in the design of the PA4318.104NLT, which features a toroidal core made of high-permeability ferrite material.The primary application of the PA4318.104NLT is for suppressing high-frequency interference in power lines. It acts as a filter, blocking any interfering signals with a frequency higher than the cutoff frequency set by the inductor. This allows the device to act as an effective shield, protecting appliances and components from power line noise. The inductor can also be used as a current limiter, inhibiting destructive current loops in circuits that require highly-controlled current levels.In addition to its suppression and current-limiting capabilities, the PA4318.104NLT is also used for various power conditioning applications such as improving power factor in switched-mode power supplies (SMPS) and in power-over-Ethernet networks (PoE), due to its high DC resistance and excellent thermal conductivity. In these applications, the inductor is used in conjunction with other components such as capacitors and resistors to create a low-pass filter circuit.Finally, the PA4318.104NLT is often used in audio and communication systems to reduce interference caused by external sources. It is particularly effective at suppressing RF interference, which is why it is so widely used in portable devices such as cell phones and PDAs. By introducing a high impedance into the circuit, any unwanted signal is effectively blocked, resulting in improved signal clarity.In conclusion, the PA4318.104NLT is a versatile inductor which offers a wide range of applications. From power line noise suppression to current limiting and power factor conditioning, the inductor has proven to be an invaluable component in modern electronics. It is also highly reliable thanks to its robust construction and high-quality materials, making it an ideal choice for any application where high-frequency interference needs to be suppressed.
