DIP Air Core Inductor Rod Core Ferrite Power Bar Core Inductor

1.Product Description

The DIP Rod Core Inductor is an inductor with a rod core and is available in a dual in-line (DIP) package.

1. Structural Components

--Core: Usually made of magnetic material such as ferrite in a rod shape. The rod-shaped core provides good magnetic permeability, which helps to enhance the magnetic field and enables the inductor to store and release energy, thus realizing its various functions in circuits.

--Coil: Generally formed by winding enameled wire around a bar-shaped core. By controlling the number of turns, wire diameter and winding method, etc., the inductance of the inductor can be precisely adjusted to meet the needs of different circuits.

--Pins: A double row in-line pin design is used. The pins are usually made of metal and have good conductivity and solderability. These pins are used to connect the inductor to a printed circuit board (PCB) or other circuit components for electrical connection.

2. Principle of operation:

Works based on the principle of electromagnetic induction. When a current is passed through a coil, a magnetic field is generated around the core. Changes in the magnetic field generate an induced electromotive force in the coil, which hinders the current. This characteristic makes the inductor in the circuit can play the role of filtering, energy storage, variable voltage, choke, etc., for example, in the power supply circuit, can be used to smooth the DC voltage, filtering out the power supply in the high-frequency noise; in the oscillator circuit, and capacitors with the formation of the LC oscillator circuit, to produce a specific frequency of signals and so on.

2.Applications

--Power Supply Circuits

1.DC-DC Conversion: In all kinds of DC-DC converters, DIP Rod Core Inductor is one of the key components. It is used to store and release energy, helping to transform the voltage up and down to ensure a stable DC voltage output. For example, in the power adapter of a laptop computer, this inductor is indispensable to convert the utility power into different DC voltages suitable for the computer.

2. Power filtering: can effectively filter out high frequency noise and ripple in the power supply, so that the output DC voltage is smoother. In the power module of industrial automation equipment, through the use of DIP Rod Core Inductor, it can provide stable and pure power for various electronic components in the equipment to ensure the normal operation of the equipment.

--Audio Circuit

1. Power Amplifier Circuit: In audio power amplifier, DIP Rod Core Inductor is often used in power decoupling and filtering to provide stable power supply for the amplifier, and at the same time, it can also improve the quality of audio signals, reduce the interference of power supply noise on audio signals, and make the audio output purer and clearer, which is widely used in audio equipments and automobile audio systems.

2. Equalization circuit: in the audio equalizer circuit, with capacitors and other components to form the LC resonance circuit, to achieve the different frequencies of the audio signal enhancement or attenuation, to meet the needs of different users of the audio effect.
