Fixed inductors are components that store energy in an electric field when current passes through them. They are used to provide inductance in applications such as dc-dc converters, motor control and SAW filters. The SC53FU-391 is a fixed inductor designed for power line and feedback circuits in current-mode buck and boost dc-dc converters. It offers high current capacity and low loss characteristics that are ideal for today’s rapidly evolving electronics industry.

The SC53FU-391 is made from a copper wire base that is wound around a magnetically treated ferrite core. The wire is covered with a heat-resistant insulating material. This construction results in a low DC resistance, a very low self-inductance, and a stable inductance over a wide range of operating temperatures.

The inductor is designed to be used in a variety of applications including power-line and feedback circuits in current-mode buck and boost dc-dc converters. The SC53FU-391 has a wide operating temperature range of −55°C to +150°C, and a high current capacity of 3.3 A. To ensure long-term reliability, the inductor has been tested to ensure that it meets the following parameters:

• Maximum current: 3.3 A
• Maximum operating temperature: +150°C
• Maximum voltage: 500 VDC
• Impedance: 20 mΩ
• Max inductance: 12.5 uH

The SC53FU-391 features an air core coil design for high reliability and a ferrite core construction for low self-inductance and high current capacity. Its low DC resistance allows it to handle currents up to 3.3 A without overheating or suffering from other operational issues. The inductor has a wide operating temperature range from −55°C to +150°C, making it ideal for use in high-temperature environments and applications.

The SC53FU-391 inductor has a low self-inductance, which helps to reduce the L/R ratio of any given system, allowing for increased working efficiency. The inductor also offers excellent EMI suppression and low core loss, resulting in higher efficiency and better performance. Its low acoustic noise allows it to be used in applications such as professional audio or acoustics.

The SC53FU-391 also offers excellent high frequency characteristics, making it suitable for use in RF circuits. It can be used in antenna matching circuits and RF power supply circuits, as well as in high frequency, high voltage converters. The inductor also provides excellent shielding and grounding for high frequency radiation from sources such as satellites or cellular phones.

The SC53FU-391 is a highly reliable, versatile inductor with a wide range of applications. Its low DC resistance, low self-inductance, low acoustic noise, high current capacity, wide operating temperature range, and excellent EMI suppression and low core loss make it an ideal choice for many applications. Whether used in power line and feedback circuits, RF circuits, or in professional audio or acoustics, the SC53FU-391 will provide reliable, high performance.
