Fixed Inductors

Fixed inductors, also known as chokes, are components used in electrical circuits as impedance transformers—usually to decrease current or voltage. They consist of conductors, typically copper or aluminum, wound in a coil which produces a specific inductance. The properties of inductors can be described by their inductance, maximum current at which they can operate without damage, and frequency response. This article will discuss the application field and working principle of FDSD0412-H-4R7M=P3, a type of fixed inductor.

FDSD0412-H-4R7M=P3 is an inductor with an inductance of 4.7 µH and a current rating of 1.47A. This type of inductor is typically used in filtering, radio frequency (RF) signal transmission, and DC to AC power conversion. FDSD0412-H-4R7M=P3 inductors can be used in various applications such as power converters, voltage regulators, switching power supplies, and low-frequency amplifiers.

The basic principle of an inductor is Faraday’s law of induction. This law states that when a conductor is moved through a changing magnetic field, a voltage across the conductor is induced. As current flows in a coil, it generates a magnetic field that, in turn, induces a voltage in the coil. The magnitude of the voltage is determined by the inductance, number of turns in the coil, and the rate of change of the current. The voltage induced in the coil will also oppose any changes in the current, which reduces the wiring inductance for electromagnetic interference (EMI) and radio frequency (RFI).

When designing with FDSD0412-H-4R7M=P3, it is important to take into account its small size and low inductance. To achieve the desired harmonic suppression, the FDSD0412-H-4R7M=P3 inductor should be positioned as close as possible to the source of noise or interference. It is also important to ensure that the inductor is correctly mounted to a grounded printed circuit board (PCB) to maintain efficiency.

FDSD0412-H-4R7M=P3 is a versatile component used in a wide range of applications. Due to its low inductance and small size, it provides effective filtering and EMI/RFI suppression while taking up minimal space. It is also capable of handling high currents without becoming damaged, making it an ideal choice for a variety of projects.
