Fixed inductors are electronic components used in a variety of radio, audio, and power applications. They vary in size and type depending on the design of the circuit and the environment in which they will operate. The PG0426.821NL is a typical one, and it has its own specific field of application and working principle.

Application Field

The PG0426.821NL inductor is a surface mount Fixed Inductors with a rated inductance of 800uH (+/-20%). It has a maximum DC current of 2.5A and a low DC resistance of 0.160 Ohm. Additionally, it has a saturation current rating of 3.25A and self-resonant frequency of approximately 7 MHz. It has a maximum temperature rating of 125°C for its operation temperature. The PG0426.821NL is typically used in DC-DC switching applications, such as automotive and cell phone power supplies. Its design also makes it well suited for applications where continuous bias current is desired.

Working Principle

Fixed Inductors work by inducing a magnetic field in a circuit when current passes through. This magnetic field then stores energy, which can be released when the current is interrupted. The PG0426.821NL inductor works in the same way. When current passes through the coil of the inductor, a magnetic field is created around it and the inductor stores the energy. When the current is interrupted, the energy is released.

The PG0426.821NL is particularly useful in applications where a steady flow of current is desired. That is because its surface mount construction provides excellent heat dissipation and better contact with the PCB, which helps maintain a stable power source. This design also protects the inductor from vibration, shock, and moisture.

Conclusion

The PG0426.821NL is a surface mount Fixed Inductors with a rated inductance of 800uH (+/-20%). It has a maximum DC current of 2.5A and a low DC resistance of 0.160 Ohm. Additionally, it has a saturation current rating of 3.25A and self-resonant frequency of approximately 7 MHz. It is typically used in DC-DC switching applications, such as automotive and cell phone power supplies, and its design makes it well suited for applications where continuous bias current is desired. Fixed Inductors work by inducing a magnetic field in a circuit when current passes through and storing energy, which can be released when the current is interrupted.
