Fixed Inductors

The SC3DF-390 from Vishay Intertechnology is a fixed inductor that can be used many applications, such as AC-DC and DC-DC electrical converters, or even as a component for power supplies, regulators, and filters for high frequency signals. This inductor features high self-resonant frequency, low damping, and high surge current capability. With a 3.90µH Inductance, this inductor is well-suited for applications where a smaller physical size and high self-resonant frequency is desired.

Features and Benefits

Applications

The SC3DF-390 fixed Inductor from Vishay are used for wide range of applications, including, but not limited to:- AC/DC and DC/DC electrical converters- Power supplies- Regulators- Filters for high-frequency signals- Filter elements for signal coupling- Oscillator circuits- Radio circuits- Frequency synthesizers

Working Principle

The SC3DF-390 fixed inductor works by inducing an electromagnetic field while a current is passed through it. This electromagnetic field stores both magnetic and electrical energy, which can then be released back into the circuit. The inductance of the inductor determines the amount of energy that is stored in the field, which in turn determines the amount of voltage that is dropped in the circuit when a current is passed through it. The inductance of this particular inductor is 3.90µH, meaning that this inductor can store more energy than a inductor of lower inductance, such as 1µH.The frequency at which the electromagnetic field oscillates is determined by the inductance, capacitance, and resistance of the circuit it is in. This frequency is known as the “Resonant Frequency”, and is one of the most important parameters for any inductor, as it determines the amount of voltage that will be dropped in the circuit. The self-resonant frequency of the SC3DF-390 is 10.20MHz, which is very high, and is ideal for high frequency applications.The damping of the SC3DF-390 fixed inductor is also important. This is the ratio of the rate of energy loss from the electromagnetic field versus the rate of increase in energy within the field. The damping of this particular inductor is 0.18 O, meaning that it will not lose energy too quickly, making it ideal for applications with a high frequency.The surge current capability of the SC3DF-390 is also important - this is the amount of current that can be passed through the inductor without it overheating or damaging the circuit. The maximum surge current capability of this particular inductor is 2.00A, so it is well-suited for applications where a large amount of current is needed.

Conclusion

The SC3DF-390 fixed inductor from Vishay is ideal for a range of applications requiring an inductor with a high self-resonant frequency, low damping, and a high surge current capability. It is a compact size, making it ideal for applications with size constraints, and its halogen-free and RoHS compliant construction make it an environmentally friendly choice. Its wide range of uses, including power supplies, regulators, and filters, make it a versatile inductor that is suitable for any number of applications.
