Fixed Inductors

Fixed inductors, also known as chokes or coils, are electronic components used to store energy in the form of a magnetic field. They are composed of a coil of metal wire wrapped around a core material, such as ferrite or magnetic powder. The purpose of a fixed inductor is to oppose or limit the flow of electric current in an AC or DC circuit. In an AC circuit, they can be used to create a phase shift, to filter or isolate different frequencies, or to provide a constant current signal to an amplifier.

The 4232–392H device is a high-performance, surface-mount fixed inductor manufactured by Murata Electronics. This type of inductor is widely used in a range of applications from radio receivers to advanced industrial electronics. The device features a monolithic design and is constructed with molded-ceramic for superior temperature stability. The 4232-392H also features ultra-low DC resistance for superior current handling capabilities.

Working Principle

The 4232-392H is based on the principle of self-induction, which states that an electrical current induces a magnetic field, and this field in turn induces an electric current. When an electrical current is applied to the 4232-392H, the core material creates a magnetic field, which is then stored in the inductor\'s coil. The amount of current passing through the coil is determined by the inductance of the device. The higher the inductance, the lower the amount of current that can pass through the coil.

The 4232-392H is particularly useful in RF applications due to its high inductance and low DC resistance. The device is capable of handling frequencies up to 2 MHz, and its low ESR (Equivalent Series Resistance) provides excellent noise reduction at these frequencies. In addition, the device has an excellent temperature coefficient of 0.2%/°C, which ensures stable operation over a wide temperature range.

Application Field

The wide range of operating frequencies allowed by the 4232-392H make it an ideal choice for many applications. The device is used in RF transmitters and receivers, active filters, and voltage regulators. It is also used in power supply circuits and other switching circuits, where the inductor is in charge of storing energy and providing a constant amount of current. The 4232-392H can also be used in data acquisition systems, since it can provide a clean, high-frequency signal for accurate data collection.

The 4232-392H is also ideal for automotive applications since it has a low current leakage and a high inductance value. The device can be used in automotive lighting systems, where its high frequency characteristics make it perfect for reducing power consumption and controlling luminance. The 4232-392H can also be used in DC/DC converters, where its low DC resistance and high inductance value ensure maximum efficiency.

The 4232-392H has proven to be a reliable and robust fixed inductor for many industrial and consumer applications. Its excellent noise reduction, high inductance value, and low current leakage make it an ideal choice for many PCBs. Its monolithic design and integrated features help reduce costs and ensure reliable operation in a variety of circuits.
