Fixed inductors are used in applications that require a specific amount of inductance in a circuit such as an oscillator, filter or power supply. An example of a fixed inductor is the TDK 3400-470ML, a fixed-value surface mount inductor.

Fixed inductors provide designers with the ability to control the amount of inductance in a circuit, ensuring the proper operation of the circuit. This is done by controlling the number of turns that make up the winding as well as the width and thickness of the wire used. In addition to the inductance, the size of the fixed inductor also affects the amount of current that it can handle.

The TDK 3400-470ML fixed inductor is a high-value, wound steel-core inductor that is used in a range of applications, from power supplies to filters. Its range of features makes it a popular choice for designers. The main features include:

• Inductance range: 30nH to 470nH
• 500mA saturation current
• Surface mountable
• Low DC resistance
• High Q
• Excellent solderability and electrical stability

The working principle of the TDK 3400-470ML fixed inductor is to store energy as a magnetic field, which is then dissipated as an electrical current within the coil when the field collapses. This stored energy is controlled using the number of turns of the coil and the wire diameter, which determines the amount of inductance the inductor can provide. The shape and size of the inductor also affects the operating frequency of the inductor. If the inductor is a small wire type, it will be able to operate at higher frequencies, while if it is a large crab-wound inductor, it will have a lower operating frequency.

The TDK 3400-470ML fixed inductor is used in many applications, most notably in high- frequency switching power supplies. It is also used in low-to-medium frequency filter networks, which are used for circuit noise filtering. The inductor is also used in broadcast and industrial supply stages for signal processing applications.

In addition to the TDK 3400-470ML, there are many other types of fixed inductors available from different manufacturers. These range from small SMD inductors to large surface mount inductors. Designers should select the right inductor for their specific application based on the inductance, size, current handling capabilities, and frequency range requirements.

Overall, the TDK 3400-470ML fixed inductor is a reliable, high-value, wound steel-core inductor that is suitable for a range of applications. Its range of features, such as its inductance range, low-DC resistance, and excellent solderability, make it the perfect choice for many designers.
