Fixed Inductors, also known as Fixed Coils or Choke Coils, are hugely important electronic components. They are used to store electrical energy or in combination with a capacitor to filter out AC from a DC supply or vice versa. Fixed Inductors can usually be found in electronics modules, power supplies, radio antennas, communications equipment and more. One of the most popular Fixed Inductors available is the RL875S-820K. This particular component is known for its high performance and low dissipation, making it perfect for all sorts of industrial applications and small-scale consumer electronics.

The RL875S-820K is a high-grade Fixed Inductors with excellent operation stability and wide frequency range. It has a basic structure of a flat coil with a plastic encapsulated base and 4 pins on both sides. It’s available in three different ratings - 8.2K, 10K and 15K - and is capable of suppressing high frequencies, usually up to and above kHz. It has a temperature coefficient of + 25℃, a maximum operation temperature of + 80℃, and a minimum of -55℃. The component is extremely versatile and can be used in a variety of different applications, from radio and communications equipment to power supplies and audio amplifiers.

One of the most common application field for the RL875S-820K is the filtering of high-frequency noise generated by power supplies and motor drives. The component is capable of rectifying power line ripple, thus removing noise and improving the stability of the system. The RL875S-820K is also perfect for DC/DC converters in order to create stable output voltage levels and reduce power losses. Similarly, the component can be used to remove interference in audio systems, thus improving the signal/noise ratio.

When it comes to the working principle of the RL875S-820K, it is based on the principle of inductance. Inductance is the characteristic property of a conducting path which allows it to store energy in the form of a magnetic field. It is one of the basic principles of electric circuit theory and is closely related to Ohm’s law and Faraday’s law of induction. When current passes through a conductor, it produces a magnetic field. This magnetic field, in turn, induces a voltage in the conductor. The inductance of a conductor is typically expressed in henries (H), with one henry being equal to a one-ohm resistor when voltage and current are measured in volts and amperes respectively.

In other words, since the RL875S-820K is a fixed inductor, its operation is based on the idea that inductance stores energy in a magnetic field which, in turn, induces a voltage in the component. This voltage is then used to remove high-frequency noise in the primary circuit. The RL875S-820K is designed to provide high-temperature stability, low dissipation, and high suppression of high-frequency noise. As a result, it is used in many different applications, such as electrical power supplies, audio systems, and communications devices.
