Fixed inductors are an important part of electronic circuitry. They are widely used in applications such as filtering, smoothing, impedance matching, signal processing and noise reduction. The 70F687AP fixed inductor is a popular choice for these applications due to its high-performance and reliable operation. In this article, we will look at the application fields and working principles of the 70F687AP.

1. Application Fields

The 70F687AP is a surface mount fixed inductor that offers a variety of applications in various industries. It can be used in the design of power line filters, DC/DC converters, audio amplifiers, and automotive power systems. Due to its high permeability, the 70F687AP is also suitable for various RF and power line applications such as antenna tuning, cable harmonics filtering, and spike current suppression.

2. Working Principle

The 70F687AP uses an air core inductor to produce a magnetic field, allowing it to store electrical energy when a current passes through it. The inductor has two separate windings that are connected in series and wound around the same core. The first winding produces a magnetic field, while the second winding opposes and reduces the magnetic field. This produces an inductance, which is the measurement of how much opposition a change in current encounters as it passes through the inductor.

The inductance of the 70F687AP can be adjusted by changing the number of turns on either winding. This allows the inductor to be tailored to specific needs, such as creating a high-frequency filter or low-frequency filter. Additionally, the 70F687AP has a high current carrying capacity, high saturation current, and low temperature rise, making it suitable for use in high-current applications such as power amplifiers.

3. Advantages

The 70F687AP has some unique features and advantages that make it a great choice for various applications. Firstly, it has a wide frequency range, allowing it to be used in a wide range of applications. Secondly, it has low DC resistance, meaning it produces less power loss than other inductors. Additionally, it has a very good temperature coefficient, meaning it maintains its characteristics over wide temperature range. Lastly, its high saturation capability makes it suitable for high-current and power applications.

The 70F687AP is an excellent choice for many applications due to its reliable performance and wide range of features. Its application fields and working principles make it suitable for use in a variety of applications, from RF and power-line applications to filtering, smoothing, and impedance matching. Furthermore, its advantages such as low DC resistance, wide frequency range, and high saturation capability make it a great choice for high-current and power applications.
