Introduction

Fixed inductors (CBMF1608T470K) are widely used in power supplies and various electronic circuits. It is designed to offer protection from electromagnetic interference and reduce power loss and current noise. The main purpose of these inductors is to convert electrical energy from alternating current to direct current, allowing it to be stored or used for other purposes.

Applications

Fixed inductors (CBMF1608T470K) are commonly used in power supplies, power regulators, and DC-DC converters. They are designed to reduce power losses, limit current surges, and filter electromagnetic signals. CBMF1608T470K fixed inductors can also be used in various circuits where high currents of varying frequencies are needed, such as AC motor drives, UPS systems, and switching power supplies.Moreover,fixed inductors (CBMF1608T470K) are used in radio communication systems.They are used to filter narrow-band and wide-band signals from noise, transform higher frequency signals to lower frequency signals, and provide DC isolation for a wide array of electronic systems.

Working Principle

Fixed inductors (CBMF1608T470K) are made of a core, usually rectangular, which is either made of powdered iron or a ferrite material. This core is surrounded by a coil of wire which creates a magnetic field when energised by electricity.The working principle is similar to that of a transformer, wherein a changing current in the first winding (primary coil) creates a time-varying magnetic flux, which in turn induces a current in the second winding (secondary coil). This changing current is what is known as an alternating current.The magnetic field created by the inductor gets tightly wrapped around its winding. This is known as ‘self-inductance’ and it acts like a brake, helping to regulate how fast the current can flow. It is this action which is used to filter out high frequency signals and provide resistance to rapid voltage changes.

Advantages

Fixed inductors (CBMF1608T470K) offer the following advantages:

• Reduced noise and improved power efficiency.
• Low power losses in switching mode power supplies.
• Low power consumption and improved performance.
• High efficiency and heat dissipation.
• Built-in EMI protection.
• Can be used in a variety of applications where high currents of varying frequencies are needed.

Conclusion

CBMF1608T470K fixed inductors offer a wide range of advantages, making them suitable for various applications. These include power supplies, power regulators, and DC-DC converters. These inductors provide power efficiency and EMI protection as well as low power consumption and improved performance. They are also useful for radio communication systems due to their ability to filter out signals and provide DC isolation.
