Introduction

Fixed inductors, also known as permanent magnets, are electronic components that store energy as a magnetic field. They are used in a variety of applications and are especially important in circuit design. This article will discuss the characteristics of the 74479887247 fixed inductor, its application field, and its working principle.

Characteristics of 74479887247 Fixed Inductors

74479887247 fixed inductors are small, low-power components made from metal or ceramic material. They are capable of holding large amounts of magnetic flux, which enables them to operate as part of larger circuits. Their rated inductance value is 8.21 µH (±30%) in an open-circuit configuration and 6.4 µH (±20%) in a closed-circuit configuration. The maximum current capacity of these inductors is 1.3 A. They are also capable of handling a peak reversed voltage of 1.7 V. Additionally, these inductors are rated for temperatures ranging from -55°C to +125°C and have a RoHS compliant tin-silver-copper finish.

Application Field

74479887247 fixed inductors are commonly used in low-power circuit designs. They can be used as motors for fans, pumps, blowers, and other small motor applications, or they can be used as part of noise suppression circuits. They are also used as part of switching circuits, like those found in power supply designs. Their small size and high current capacity makes them ideal for these applications.

Working Principle

The 74479887247 fixed inductor works on the principle of electromagnetic induction. When current is passed through a coil, it produces a magnetic field. This field in turn induces an electromotive force across any portion of the coil. The magnitude of the electromotive force is proportional to the magnitude of the current and the number of turns in the coil. This induced voltage is then used to power the circuit. When the current is changed, either by reducing it or increasing it, the magnetic field within the inductor also changes, resulting in a change in the induced voltage. This allows the inductor to be used to stabilize the voltage of the circuit and to filter out any AC components.

Conclusion

74479887247 fixed inductors are a versatile type of component that can be used in many different applications. They are small in size, allowing them to be integrated into circuit designs without taking up too much space. They are also capable of handling large amounts of current, which makes them ideal for small motor applications. Furthermore, they work on the principle of electromagnetic induction, allowing them to be used to regulate the voltage of a circuit.
