Fixed inductors are electrical components used to create a magnetic field on alternating current (AC). They are used to filter out unwanted frequencies, and to create time delay for waveforms such as in oscillators, amplifiers, and receivers. The RL855-391K-RC is a type of fixed inductor, designed for a wide range of applications. In this article, we will discuss its application field and working principle.

Overview Of RL855-391K-RC

The RL855-391K-RC inductor is a high voltage, low RMS current rating, and a low profile chip form factor fixed inductor. It is manufactured from laminated black polycarbonate for on-board reliability and made with an integrated silver plating construction for better electrical and thermal characteristics. It is operated up to a temperature range of -55 to +85°C, and is available in a variety of shapes from granule to square. The advantage of this inductor is that it is low profile, allowing it to be mounted on surfaces with limited space, and it is very well-suited to high-density electronic systems.

Application Field

The RL855-391K-RC is a reliable fixed inductor designed for many applications, ranging from consumer electronics and telecommunication equipment to high-end industrial control systems. Its integrated silver plating construction allows it to have high current and good heat dissipation characteristics, making it suitable for use in DC-DC power converters, switching power supplies, and other current-based applications. Besides the power factor correction (PFC), this inductor is also suitable for multiple ac-to-ac conversion, which is particularly applicable in the automotive, computer, and solar powering markets. Additionally, this inductor is used in many RF applications as a coil in antenna systems to filter out higher frequencies.

Working Principle

At the heart of the operation of the RL855-391K-RC fixed inductor lies Faraday’s law: a change in the magnetic flux through a circuit produces an electromotive force (EMF) across the circuit. This EMF is proportional to the rate of change of the magnetic field and is known as inductance, L. This inductance is produced as current flows through the inductor, creating a magnetic field. When the current is turned off, the magnetic field collapses and generates a voltage in the opposite direction, thus providing an inductive voltage.

The RL855-391K-RC fixed inductors are designed to operate in this principle with a constant inductance value and ripple current over a wide range of conditions. They also have a high isolation voltage, meaning that the inductance is not affected by any other components or systems in the circuit. The design also includes a high self-resonance frequency to ensure that the inductance remains consistent when operating at different frequencies.

Conclusion

The RL855-391K-RC fixed inductor is a versatile component, suitable for many applications and working conditions. Its integrated silver plating construction provides it with higher current ratings and good thermal dissipation abilities, making it suitable for use in power converters, switching power supplies, and RF applications. Its low profile design makes it suitable for installation in systems with limited space, and its constant inductance and ripple current ratings make it a reliable component. In conclusion, the RL855-391K-RC is a highly recommended fixed inductor for a variety of applications.
