Fixed Inductors: B82477D4472M000

Fixed inductors are an integral part of many electrical and electronic circuits. The B82477D4472M000 is a balanced, shielded, surface mount power inductor made by EPCOS, designed to be a reliable and efficient low-loss component in a wide range of applications.

Applications:

The B82477D4472M000 has a high initial rate-independence and low losses, making it suitable for many applications. It can be used in numerous high-power circuit designs, including power supplies, high-current converters, radiofrequency applications, filter circuits, and other similar types of circuits. In addition, it can be used in pulsed circuits and with DC-DC converters to reduce electromagnetic interference (EMI).

Design and Construction:

The B82477D4472M000 is made using a ferric-powder core and has a cylindrical shape. It’s electrical leads are 5mm in length and the body is made of laminated steel. Its inductance range is between 0.1 and 4.7µH. The maximum rated current for the B82477D4472M000 is 8A and its operating temperature range is -40°C to +125°C. The maximum rated voltage for the B82477D4472M000 is 5V. The inductor is shielded for protection against EMI. The shielding material is ferrite, which has a low magnetic field leakage and a low permeability. The shielding is designed to reduce the inductor’s external noise and interference, allowing it to be used in more severe EMI environments.

Working Principle:

The working principle of fixed inductors revolves around the concept of inductance. Inductance is an electrical property that can be found in coils and other conductive materials, and is responsible for the production of an electromagnetic field when current flows through them. For the B82477D4472M000, the inductance is produced by the passage of electrical current from one coil to another. The coil acts as a bridge between the positive and negative terminals, and as current passes through it, an electromagnetic field is created due to the effects of inductance. This field is then used to regulate the current and reduce the amount of electrical noise in the system.The shielding material used in the B82477D4472M000 enhances its effects by further reducing the amount of EMI that could potentially interfere with the system. The ferrite material is designed to have a low magnetic field leakage and a low permeability, making the inductor ideal for use in high-power circuit designs.

Conclusion:

The B82477D4472M000 is a balanced and shielded surface-mounted power inductor made by EPCOS. Its design makes it suitable for a wide range of applications, from power supplies and high-current converters to filter circuits and radiofrequency applications. The inductor’s shielding material reduces the amount of EMI that could potentially interfere with the system, allowing it to be used in more severe EMI environments. The working principle of the B82477D4472M000 revolves around the concept of inductance, with an electromagnetic field being produced as electrical current passes through it.
