Fixed inductors are passive electrical components used to store energy in an electric field. Commonly referred to as ‘chokes’, they are used in a variety of applications. One such example is the 77F180K-TR-RC series of fixed inductors.

The 77F180K-TR-RC series of fixed inductors is designed for a range of regulation of fixed values from 0.47mh to 1.4mH and rated currents up to 3.2A max. These inductors are built to a precise tolerance and provide low DC resistance, making them ideal for applications requiring high power and regulation, such as power supplies, motor control, automotive applications, and DC/DC converters.

The 77F180K-TR-RC series of fixed inductors also have a high efficiency rating, with a low core loss and high modulation stability. This is due to their non-linear magnetic core, a combination of high-flux circular magnetic wire and a ferrite core. This combination provides excellent current and frequency response, enabling fast switching and high switching frequency applications. This type of design also helps reduce EMI and RFI.

The 77F180K-TR-RC series of fixed inductors can operate in environments with temperatures ranging from -40°C to +105°C, with an operating temperature range of -40°C up to the specified temperature of +105°C. These inductors are also RoHS compliant and environmentally friendly, offering assured long-term operational stability.

The working principle of fixed inductors such as the 77F180K-TR-RC series is based on Faraday’s law of induction; when current is flowing through the inductor, an electromagnetic field is created, storing energy in the electric field which can then be released when the current is reversed or interrupted. This stored energy is proportional to the current squared and the inductance. When current flows through the coil, the magnetic field created by the current induces a voltage in the other side of the coil, this voltage is known as back-EMF. Back-EMF helps prevent current overshoot, leading to more stable operation.

The 77F180K-TR-RC series of fixed inductors are ideal for a variety of applications. They are designed to provide a precise regulation of values, a wide operating temperature range, high modulation stability, and low core loss. This makes them the perfect choice for power supplies, motor control, automotive applications, and DC/DC converters where precise regulation of values and stability is essential.
