Fixed inductors are electrical components that act like electromagnets to store electrical energy for later use. They consist of a coil of wire wrapped around a core material, either ferromagnetic or ferrite. The core material is responsible for increasing the inductor’s field strength and current carrying capacity, and the coil of wire creates a magnetic flux in the core when current passes through it, inducing an electrical voltage in its windings. The amount of inductance is governed by the core material’s electrical resistance, the winding turns, and the distance between turns.

The P1812-123G is a fixed inductor that is particularly well-suited for several different types of applications. It is small in size, measuring just 1812mm in length and up to 6mm in width, and has a high inductance value of up to 123nH, making it ideal for circuits requiring high bandwiths and data rates. It also has a low DC resistance, allowing it to handle high-current applications without compromising its performance. Furthermore, it has a high SRF (self-resonant frequency), which enables it to maintain its performance in circuits operating at frequencies of up to 1GHz.

In terms of its working principle, the P1812-123G consists of a coil of wire wrapped around a ferrite core. When current is passed through it, the coil of wire creates a magnetic flux in the core, which induces an electrical voltage into the coil. The amount of inductance is determined by the electrical resistance of the core material, the number of windings in the coil, and the distance between each winding turn. Additionally, the high SRF of the P1812-123G enables it to maintain its performance even at high frequencies.

The P1812-123G has a wide range of applications, including in multi-layer ceramic capacitors, high frequency circuits, power amplifiers, and switching power supplies. Its small size and high inductance value make it particularly well-suited for high frequency circuits, where it can be used to store energy, filter signal frequencies, or stabilize the output voltage in power supplies. It is also ideal for power amplifiers, where it can maintain a high degree of linearity even at very low frequencies, and for switching power supplies, where its low DC resistance allows it to handle high-current applications without compromising performance.

In summary, the P1812-123G is a fixed inductor that is particularly well-suited for several different types of applications. It has a small size, high inductance value of up to 123nH, low DC resistance, and high SRF, which enables it to maintain its performance even at high frequencies. It is ideal for high frequency circuits, power amplifiers, and switching power supplies.
