Fixed inductors are a type of electrical device made with two or more conductors. Traditionally, these conductors are wound in a coil for better performance and stability. Also known as chokes, these passive components can store energy for a short period before releasing it back into the circuit. Most inductors are composed of a core material, such as iron or ferrite, and a coil or winding made of wire or other conducting material. Depending on the type of inductor, the core type and size, as well as the number of turns in the coil, will vary. In this article, we will explain the application field and working principle of the 77F120K-TR-RC.

The 77F120K-TR-RC is a power inductor from the TONAL series made by Delta Electronics. It is a through-hole molded device, built with a ferrite core and several windings of copper wire. It has a rated current of 5A, an inductance of 120 μH, and a low-resistance of 0.018Ω. The inductor offers excellent frequency characteristics and high current handling with low-loss. Due to its small size and low weight, it is ideal for use in a wide range of applications, such as DC/DC converters, DC/AC filters, and other power circuits.

A basic understanding of the working principle of inductors is necessary to understand the applications of the 77F120K-TR-RC. When current passes through an inductor, a magnetic field is created around the conductor. The magnetic field stores energy in the form of an electro-magnetic field. As the current passes through the inductor, this energy is released in the form of an electro-magnetic wave. When the current is removed, the energy stored in the electro-magnetic field is also reduced until it eventually dissipates. So, as the current increases, the energy stored increases, and as the current decreases, the energy stored decreases. This is known as the inductor’s “inductance”.

The 77F120K-TR-RC is especially suited to DC-DC converters due to its low-loss, high current-handling, and frequency characteristics. In these converters, DC power is converted to AC power. The inductors store and release energy in the form of an electro-magnetic wave, which is then converted to the desired AC frequency. The inductor helps regulate the current and limits the voltage, which ensures a consistent output voltage. This makes it ideal for use in applications that require a stable, clean signal.

The 77F120K-TR-RC is also ideal for use in power distribution networks. In these networks, inductors help reduce power losses and even out sudden voltage changes. The inductor prevents voltage spikes by reducing input voltage and helps to stabilize frequency by storing and releasing energy in the form of an electro-magnetic wave. This helps to ensure that the power output is consistent and reliable.

The 77F120K-TR-RC can also be used in DC/AC filters. In these systems, the inductors help reduce interference by filtering out high-frequency noise. The inductor stores and releases energy in the form of an electro-magnetic wave, which reduces the noise. This helps to ensure that the output signal is clean and free from interference.

To conclude, the 77F120K-TR-RC is an ideal power inductor for a wide range of applications. Its low-loss, high current-handling, and frequency characteristics make it suitable for use in DC/DC converters, power distribution networks, and DC/AC filters. With its attractive pricing and excellent performance, the 77F120K-TR-RC is a great choice for any application.
