Fixed inductors are used in a wide variety of applications, from power supplies to air conditioning systems. The SCPH73B-100 is a popular fixed inductor due to its high efficiency, low noise level, and wide range of applications. This article will discuss the applications of the SCPH73B-100, its working principle, and provide insight on how it can be used in various circuits.

Application Field of the SCPH73B-100

The SCPH73B-100 is a fixed anti-jam ferrite core inductor, which is commonly used in power supplies and other power electronic circuits. It can be used for EMI filtering, flyback transformer turns ratio correction, and primary-side D.C. bias of thyristor modules. Additionally, this inductor can be used in various applications such as air conditioners, speakers, measures, and microcontrollers where EMC performance is required.

The SCPH73B-100 has a wide operating temperature range from -40 to +125 degrees Celsius. This makes it suitable for a variety of industrial applications. It also has a leakage flux density of 800mA/m and is able to withstand high frequency and voltage conditions. Additionally, this inductor has a high insulation resistance which allows for stable signal transmission.

Working Principle of the SCPH73B-100

The SCPH73B-100 is a fixed inductor which consists of a ferrite core and a winding coil. The ferrite core is an insulating material which contains nickel-zinc ferrite. The coil is made of an alloy with a permittivity (εr) of about 1000 and is placed between the magnetic field of the core. When an AC current is applied to the coil, a magnetic field is generated between the core and the coil, allowing for a steady and consistent current flow.

The current flowing through the coil generates a magnetic field around it, which induces a voltage in the coil. This voltage is then used for various applications such as power transformation, attenuation, and filtering. The SCPH73B-100 can also be used as an EMI filter by creating an inductive impedance which can reduce the radio frequency interference.

Uses of the SCPH73B-100

The SCPH73B-100 has a range of uses, and can be used in both commercial and residential applications. It can be used in air conditioning systems, motor control systems, and power supplies. It can also be used for EMI filtering, reducing the radio frequency interference which can interfere with other electronic devices. Additionally, it can be used for various flyback transformer turns ratio corrections and primary-side D.C. bias of thyristor modules.

The SCPH73B-100 can also be used in a power supply circuit. It can be used as an inductor in a buck, boost, or buck-boost converter circuit. In a buck converter, the inductor is used to reduce the output voltage as the current increases, while in a boost converter, the inductor is used to increase the output voltage. In a buck-boost converter, the inductor works in both directions, reducing and increasing the output voltage.

Conclusion

The SCPH73B-100 is a fixed inductor with a variety of applications. It is used in air conditioning systems, motor control systems, power supplies, and other circuits where EMC performance is required. This inductor is made of an alloy with a permittivity of 1000, and contains a ferrite core with nickel-zinc ferrite. It also has a wide operating temperature range and is able to withstand high frequency and voltage conditions. Additionally, it can be used in a variety of power supply circuits, such as a buck, boost, or buck-boost converter circuit.
