HC9-4R3-R Inductors, Coils, Chokes

Fixed inductors are passive two-terminal electronic components that are primarily used to store energy in the form of magnetic field. This type of inductor is typically used in electrical circuits to increase or decrease current flow within a particular range or when an electrical signal of a certain frequency are needed. An example of a fixed inductor component is the HC9-4R3-R. In order to understand how this type of inductor works, a few specifications regarding the HC9-4R3-R must be discussed.

Application field

The HC9-4R3-R is primarily used in high current DC applications where the inductance must remain constant. It is usually used in signal filtering and high voltage DC/DC converters. This type of component also finds application in aircrafts, medical equipment, and other highly sensitive applications. Additionally, the HC9-4R3-R can be used as a taut capacitor in chopper-type circuits.

Working principle

Fixed inductors work on the same principle as coils such as those found in a transformer. A fixed inductor consists of a coil of wire around a core or bobbin. When current passes through this coil of wire, it creates a magnetic field. This magnetic field stores energy like a capacitor or battery stores energy in the form of electrical charge. The more current that passes through the coil, the stronger the magnetic field and the more energy is stored. When the current is removed, the magnetic field starts to decay and it releases its stored energy back into the circuit.

The HC9-4R3-R is a unique type of fixed inductor since it has a low nominal inductance of 4.3 mH, high saturation current of 25 A, and a high maximum operating temperature of 125°C. This makes it an excellent choice for high-current DC applications. Additionally, the HC9-4R3-R features a low resistance of 0.006 ohms, allowing for high efficiency in its operation.

Conclusion

The HC9-4R3-R is a powerful and efficient fixed inductor component that can be used in a variety of high current DC applications. It features a low nominal inductance, low resistance, and high saturation current which make it ideal for such applications. Additionally, it can be used in aircrafts, medical equipment, and other highly sensitive applications due to its high operating temperature.
