Fixed Inductors

A fixed inductor is an electrical component that typically consists of a core material with a coil of wire wrapped around it. The primary purpose of a fixed inductor is to create a connection between two points in an electronic circuit that prevent changes in the inductance across those points. The SCPH73B-150 is a series of fixed inductors manufactured by Sanyo Denki Co., Ltd. for applications that require high-frequency and high-temperature operation. This paper will discuss the application field and working principle of the SCPH73B-150 series of fixed inductors.

Application Field

The SCPH73B-150 series of fixed inductors is a polymeric type device suitable for use in high temperature or high frequency applications. It is specifically designed for use in electronic equipment such as medical, aerospace, automotive, and other industrial products. It is also designed for use in consumer electronics such as digital cameras, cellular phones, televisions, and other digital media devices. The SCPH73B-150 series of fixed inductors can operate at up to 150°C and can handle high frequencies from 1MHz-1GHz. The size of these inductors is small compared to traditional inductors, allowing for compact designs and easier integration into products. The SCPH73B-150 series of fixed inductors are also resistant to high temperatures, moisture, and vibration, making them well-suited for high-temperature applications and harsh environments.

Working Principle

The SCPH73B-150 series of fixed inductors work by generating a magnetic field when electric current passes through the coil of wire. This magnetic field interacts with the core material to form an electromagnetic field. This field creates an inductance, which is a measure of how much energy is stored in the magnetic field around the inductor. The larger the inductance, the more energy is stored in the magnetic field and the more effectively the inductance will conduct electricity. When electricity is passed through the inductor, two effects are created. The first is a current that is passed through the inductor, known as the primary current. The second effect is the electromagnetic field generated by the inductor, which opposes the primary current, reducing the rate at which the current flows through the inductor. This is known as the inductive reactance, which is a measure of how much the current is being opposed. The SCPH73B-150 series of fixed inductors is designed to maintain a relatively constant inductance over a wide range of operating temperature and frequency. This helps to ensure that the inductive reactance remains stable, resulting in a more consistent current flow as the device is operated.

Conclusion

The SCPH73B-150 series of fixed inductors are a series of high-frequency and high-temperature fixed inductors manufactured by Sanyo Denki Co., Ltd. They are designed for use in a variety of applications, including medical, automotive, aerospace, and consumer electronics. These devices can operate in a wide range of conditions, including high temperatures, moisture, and vibration, and are well-suited to both high-temperature applications and harsh environments. The devices also maintain a relatively constant inductance over a wide range of temperature and frequency, resulting in a more stable current flow.
