Fixed inductors are electrical components used in a variety of electrical circuits, including radio frequency (RF) circuits, audio signal circuits, power management and more. The 1945R-20G fixed inductor is a commonly used component due to its low cost, small profile and large inductance. In this article, we will discuss the application field of the 1945R-20G fixed inductor and its working principle.

Application Field

The 1945R-20G fixed inductor is typically used in a variety of applications, including, but not limited to, the following:

• Switching power supplies
• Audio power amplifiers
• Low-noise amplifiers
• DC-DC converters and inverters
• RF circuits

The 1945R-20G fixed inductor has an inductance of 20 uH with a tolerance of ±10%, a maximum rated current of 4A, and a maximum rated voltage of 215V. This gives it a wide range of applications in the above listed fields. Furthermore, due to its small size, it is often used in applications where space is limited.

Working Principle

A fixed inductor is a basic type of electrical component that consists of a coil of wire with a magnetically permeable core. It blocks AC signals and stores energy in the form of a magnetic field. The most basic components of a fixed inductor are:

• A coil of wire
• Magnetically permeable core
• Terminal caps
• Wire connection

The coil of wire is wrapped around a magnetically permeable core, which boosts the magnetic field generated by the coil of wire. This magnetic field then induces a current into the adjacent coil. The current is then supplied to the terminal caps, which can be connected to a different circuit. The 1945R-20G fixed inductor works in a similar manner. Its coil of wire is wrapped around a core that boosts its magnetic field, which then induces a current into the adjacent coil.

The 1945R-20G fixed inductor is a great choice for a variety of applications due to its low cost, small profile, and large inductance. It is often used in switching power supplies, audio power amplifiers, low-noise amplifiers, DC-DC converters, and inverters, as well as RF circuits. Furthermore, its working principle is based on a coil of wire wrapped around a magnetically permeable core, which boosts its magnetic field to induce an electrical current.
