Fixed inductors are like electrical coils, and their purpose is to provide power conditioning for power circuits. They can be used to filter out unwanted noise or interference, reduce ripple in dc power supplies, or control the flow of power through circuits. The RL855-220K is a type of fixed inductor widely used in a variety of applications. In this article, we will look at the applications and working principle of the RL855-220K.

Applications of the RL855-220K

The RL855-220K is a general purpose, fixed inductor with a high saturation current of up to 1.7A and high resistance rating of up to 200mOhm. Thanks to these features, it can be used in many applications where direct current power conditioning and filtering is required. These include:

• DC-DC converters.
• Switching power supplies.
• Charge pumps.
• switching regulators.
• Lighting ballasts or dimming systems.
• Motor speed and servo control.

In addition, the RL855-220K is widely available in a range of package sizes to suit a variety of installation conditions. These packages include lead-free designs, as well as standard through-hole packages.

Working Principle

The RL855-220K is a type of inductor that relies on an induced current for its functioning. The electrical current creates a magnetic field which in turn induces a voltage in the coil. When a voltage is passed through the coil, it produces a current, which is then transferred to the surrounding circuit.

The most important feature of an inductor is its ability to store energy. The RL855-220K has an excellent energy storage capacity, due to its high saturation current rating and high resistance rating. This makes it ideal for use in a wide variety of applications, such as switching power supplies, charge pumps, and motor speed and servo control.
