Fixed Inductors

Inductors are components that store energy in the form of magnetic fields and indicate opposition to the change of electric current. Fixed inductors, a type of inductor, are made of physical spools of wire with a core material. They are available in two categories: air cores and ferromagnetic cores.ER1025-70KM is a type of fixed inductor produced by Coilcraft. It is a radial leaded fixed inductor featuring low DCR, high inductance, and a very high Q factor. This inductor is ideal for use in power supplies, resonators, RF circuits, digital circuitry, and motor control.

Application Field

ER1025-70KM has a wide range of applications due to its large inductance range and high Q factor. It is commonly used in power supplies, resonators, RF circuits, digital circuitry, and motor control. For example, ER1025-70KM can be used in motor control circuits where large inductance is needed. It can also be used in RF circuits, such as filters and amplifiers, to provide stable frequency response. Furthermore, it can be used in digital circuitry, such as capacitive charge pumps and voltage regulators, to provide stable current and voltage.

Working Principle

The ER1025-70KM fixed inductor is a conductive charge element made up of a wire with a core material, such as ferrite or iron, that stores electrical energy in the form of a magnetic field. When a current passes through an inductor, it creates a magnetic field that stores energy in the inductor. When this current is changed, the magnetic field rapidly collapses and releases the stored energy, creating an “inductive kick”. This surge can result in voltage spikes or current peaks, both of which are undesirable in circuit designs.The ER1025-70KM fixed inductor also features a low DCR and a very high Q factor, which is the ratio between reactive and resistive components. A higher Q factor means that the inductor can hold more energy for a given amount of current, resulting in a greater efficiency. In addition, the higher Q factor also reduces losses due to heat, which can cause damage to the inductor and surrounding components.

Conclusion

ER1025-70KM is a type of fixed inductor produced by Coilcraft that is ideal for use in power supplies, resonators, RF circuits, digital circuitry, and motor control. It features a low DCR and a very high Q factor, which allow it to store more energy and have greater efficiency than other types of fixed inductors. With its wide range of applications and reliable performance, the ER1025-70KM fixed inductor is a great choice for any designer looking to use a fixed inductor in their next design.
