Fixed Inductors

A fixed inductor, also known as a choke, is a type of electrical component that stores energy in its inductive properties. Its primary purpose is to limit the amount of current passing through a circuit by providing a high impedance path. It is used in a variety of electronic systems, and is essential in many applications due to its low cost, small size, and wide range of functions.

The B82498F3101J001 is a fixed inductor designed for space-constrained applications. It features a low DCR rating, low profile, and high saturation current for maximum energy storage efficiency. The inductance rating is 10mH with a 10% tolerance. The construction features a 2-pin snap-in design with a 6.5mm lead space for easy installation.

The primary application of the B82498F3101J001 is in power conversion circuits, such as DC-DC converters and AC-DC converters. It is used to provide a high inductance path for current to pass through, limiting the amount of current that can flow to the load. It can be used as an inductor to reduce current ripple in switching power supplies, or as a filter in audio applications to reduce high-frequency noise. It can also be used as a choke in telecommunication circuits, allowing only desired frequencies to pass while rejecting others.

Working Principle

The working principle of a fixed inductor is based on its inductive nature. When an alternating current (AC) travels along a wire with a certain amount of inductance, the energy in the current is transformed into a magnetic field. This field then acts against the AC current, resulting in the current changing direction at a slower rate. This is known as inductance, and it is the basis for the operation of a fixed inductor.

The B82498F3101J001 has a high saturation current rating, which enables it to effectively store the energy in a short duration of time. This allows it to limit the amount of current passing through a circuit, while still providing sufficient current for the desired operation. It can also be used to block frequency components, allowing desired frequencies to pass while rejecting others. In power conversion circuits, the inductor can reduce the current ripple, resulting in efficient power delivery.

Conclusion

The B82498F3101J001 fixed inductor is an essential component in many electronic systems. It is designed for high saturation current, low profile, and space-constrained applications. Its primary application is in power conversion circuits, where it is used to limit the amount of current passing through a circuit, reduce current ripple, and filter audio noise. The working principle is based on its inductive properties, which store energy in a magnetic field and then acts against the AC current.
