Fixed Inductors

Inductors, also commonly known as coils, are passive electrical components consisting of a wire that has been wound into a physical coil shape. To perform their function, inductors employ a magnetic field usually generated by passing an electric current through the coil. This basic principle besides the physical size and coil body material make inductors a widely used component in a variety of semiconductor circuits, and the range of inductor applications and types reflect this.

One of the primary roles of inductors in circuits is the storage and release of electrical energy. A common example of inductors used for this is in an AC power regulator. In such a device, the current passes on to an inductor where it is stored, and then released into the regulator circuit to ensure that a stable flow of energy is maintained. Alternatively, inductors can be used to generate and store a voltage at a steady level for as long as required.

Fixed Inductors are a type of inductor that uses a single core material, most commonly ferrite, iron, and powdered iron. This core material can be combined with a wire winding to form a variety of inductors in terms of physical size, inductance, and magnetic characteristics. Fixed Inductors are intended for use in circuits that require a static state, such as energy storage, filter circuits and loop systems. Due to their static state nature, they are not suitable for applications in dynamic circuits, such as those found in the telecommunications industry.

IMS05WDRU472J40 Application Field and Working Principle

The IMS05WDRU472J40 Fixed Inductor from Keysight Technologies is a high quality, surface mount inductor suitable for a wide variety of applications. It is composed of a ferrite core and copper wire wound on top of it. The IMS05WDRU472J40’s 2.2mm low profile helps to keep the inductor in close contact with the board which in turn helps to reduce the size of the device and its effects on the surrounding circuitry. The component is also rated for an operating temperature range of -55°C to +125°C.

The IMS05WDRU472J40 offers a low distributed capacitance that helps to reduce if not completely avoid high frequency circulation. In terms of impedance, there is a resistance between the windings of the inductor, and this resistance affects the performance of the electronic device in a circuit. The inductor helps to reduce this kind of impedance. Such a design allows the fixed inductor to remain unchanging in its characteristics, while providing a high degree of efficiency and performance.

The inductance for this particular inductor is 0.9 Mh - 2.2 mh depending on different operating frequencies. It also has a rated current of 0.84A and a maximum DC bias current of 1.6 A. The IMS05WDRU472J40 has a high frequency operation up to 100 MHz and a series resistance of 0.5 Ohms. The operating temperature range for this particular component is -55°C to +125°C.

Applications for the IMS05WDRU472J40 Fixed Inductor range from cellular phone communication to automation and detection. It is an ideal choice for applications that require a low-profile, high current carrying capability, as well as for low EMI/RFI applications. Its applications also include power-supply circuits, loop systems, filter circuits and energy storage.
