Fixed inductors, are often referred to as "chokes" or "coils," and are used to store and transfer electrical energy in a variety of designs. Among their many applications, they are often used in power amplifiers, DC/DC converters, AC/DC converters, antennas, filters, and ohmmeters. The 5022R-821F is a widely set among these inductors.

The 5022R-821F is a type of bobbin-wound fixed inductor, capable of chock-holding up to a 20A rated current (RMS) with a high saturation resistance of 110mΩ and a low DCR of 0.074Ω. Compared to other types of inductors, it has a relatively high thermal stability. The 5022R-821F features stronger and more stable magnetic characteristics, and it is able to bear stronger currents.

The 5022R-821F has a very long life-span, coinciding with its high current leakage resistance. It is can also withstand strong external vibrations and hardened materials. The 5022R-821F has an operating temperature of -55°C to 125°C with a storage temperature that can reach up to 125°C. Additionally, it is hermetically sealed with high reliability and has a DCB substrate, making it suitable for most industrial applications.

The 5022R-821F fixed inductor is used for various applications, such as switching power supplies, computer power supplies, UPS’s, mobile chargers, high-frequency power supplies, car audio applications, and switching regulators. This inductor is designed to provide reliable electromagnetic performance in the conditions of high temperature, high current, and high frequency. The 5022R-821F helps to protect electric circuits from high currents while simultaneously delivering stable and reliable power with low noise.

The working principle of the 5022R-821F inductor is relatively simple. When an Alternating Current (AC) flows through it, a revolving magnetic field is formed in the core due to the alternating direction of the current. This revolving magnetic field is what constricts and controls the flow of current, resulting in an induced emf. This induced emf creates a reverse current which is effectively cancelled out by the input current. The energy stored in the inductor is released when the input current is interrupted, thus creating a delayed curve within the current.

In conclusion, the 5022R-821F is a widely used component among fixed inductors. It is known for its long life-span and boasts features such as a high current leakage resistance, strong external vibrations, a high thermal stability, and a high saturation resistance. It is suitable for a wide variety of industrial applications due to its strong and stable magnetic characteristics. The working principle of the 5022R-821F is relatively simple, as it relies on the fact that a revolving magnetic field is created when an alternating current flows through it.
