Fixed inductors are commonly used components in the field of electrical engineering. Their applications range from basic DC circuit operation, to frequency-dependent LC circuits, motor control, and power conversion. The RL855-390K is one such fixed inductor that has applications in several key areas. This article will discuss the RL855-390K application field and working principle.

The RL855-390K is a surface-mount inductor from the Dongfeng Electronics Co., Ltd. It has a maximum operating frequency of up to 50MHz and is designed for use in high-density circuits. It offers low parasitic capacitance and low DC resistance, making it ideal for filters, high-frequency amplifiers, and low-power switching devices. The inductance range of this device is 0.47uH to 39nH, with a tolerance of 5%.

The RL855-390K is a popular choice for DC-to-DC conversion power supplies. It is especially useful in the power stages of voltage regulators, where it ensures smooth filtering of ripple and prevents overshoot and undershoot. It also helps to suppress sudden voltage spikes. As part of an active filtering network, the RL855-390K can help shape a high-quality power supply to meet a wide range of current and voltage requirements.

In addition, the RL855-390K is known for its use in motor control circuits. In particular, its low DC resistance and high inductance enable smooth motor current transitions, improved system accuracy, and reduced motor noise. The device can also help regulate current spikes to further reduce power losses.

The RL855-390K works on the basic principle of electromagnetism. When a current passes through a coil of wire, a magnetic field is generated. The resulting electromagnetic force creates a linear inductance that resists any change in the current, thus forming a loop of energy storage. The inductance of the RL855-390K ensures that the current maintains its direction and magnitude, allowing for a stable voltage source with minimal energy dissipation.

The RL855-390K is also known for its use in RF and microwave circuits. Its low parasitic capacitance allows it to operate efficiently at frequencies up to 50MHz, making it well suited for high-frequency switching applications and amplifiers. The inductor also offers excellent RF shielding, protecting sensitive circuitry from interference.

Thanks to its combination of features, the RL855-390K has become a popular choice for a wide range of applications. Whether it’s being used for low-power switching, power supply filtering, or motor control, the RL855-390K offers reliable performance and excellent value for money. Its low DC resistance and high inductance make it an ideal choice for many tasks.
