SRE6603-471M

Fixed inductors are components that store energy in the form of magnetic fields when electrical current flows through them. They are used in a variety of electrical and electronic circuits, including radio frequency (RF) transmitters and receivers, filters, and switching power supplies. The SRE6603-471M is a type of fixed inductor that is used in many applications.

Application Fields of SRE6603-471M

The SRE6603-471M is a mid-range fixed inductor offering high current and low saturation. It can be used in a wide range of electronic circuits, including RF transmitters and receivers, filters, and switching power supplies. It is also commonly used in other applications, such as DC/DC converters, power line filter networks, and class-D audio system power supplies.

The SRE6603-471M has impressive electrical characteristics, such as a low DCR (0.077 Ω max), and a high inductance (470 μH min) at a nominal current rating of 7 A. Its low profile (8 mm height) makes it suitable for mounting directly onto a PCB. It also has a high saturation current rating, allowing it to handle power surges without saturating.

Working Principle of SRE6603-471M

The SRE6603-471M is a magnetic core inductor that works on the principle of electromagnetic induction. When current flows through the coil, it produces a magnetic field around it. The strength of the magnetic field is determined by the current, number of turns in the coil, and the type of core material used in the inductor. This magnetic field stores energy in the form of a magnetic field.

When the current is cut off, the coil produces a voltage spike, as the magnetic field collapses and the inductor releases the stored energy. This voltage spike is used to power the circuit when a direct current source is not available. The voltage spike can also be used to activate the switching element in a power supply, or the transmitter and receiver in an RF circuit.

Conclusion

The SRE6603-471M fixed inductor is a versatile component that is used in a wide range of electrical and electronic circuits. It offers good electrical characteristics and a low profile, making it suitable for direct mounting onto a PCB. It works on the principle of electromagnetic induction, storing energy in a magnetic field and releasing it when the current is cut off.
