Fixed Inductors

Inductors are a passive electrical component used as a part of electrical circuits and are known for their ability of producing a magnetic field. The application of the inductor can be seen in many different fields, ranging from consumer electronics, telecom/datacom, automotive, and more. A fixed inductor, such as 36501E47NJ, is an electrical component with a specific inductors that is not adjustable. This particular inductor device works in several different power supply designs.

36501E47NJ Application Field & Working Principle

The 36501E47NJ fixed inductor is a voltage regulator component which can be used in a variety of power supply designs. The main application fields for the 36501E47NJ are switching power supplies, such as in power over Ethernet networks or automotive fuel pumps. These devices are typically found in areas where a consistent, regulated power supply is required. The device is composed of a metal substrate and a specific inductance rating, which helps it regulate power in these applications.The structure and working principle of a fixed inductor is fairly simple. The inductance rating of the device, measured in Henries (H), determines the amount of current that the device can store when a voltage is applied to it. As the current passes through the inductor, it creates a magnetic field which opposes any changes in the current’s direction or magnitude. This is due to the principle of Faraday\'s law of induction. The components within the device prevent a high-frequency current from passing through, therefore allowing for the regulation of voltage and current.

Types of Fixed Inductors

Fixed inductors come in a variety of different types for various applications. These inductors are usually categorized into two main types: surface mount inductors (SMT) and through-hole inductors (THT). Surface mount inductors, such as 36501E47NJ, are smaller inductors that can be placed directly onto the surface of the printed circuit board (PCB). They are advantageous in that they require less space and are more durable than through-hole devices. However, they may be harder to mount and are more susceptible to high-frequency noise produced by other components on the board.Through-hole inductors are larger components which require more space on the PCB and can usually be identified by their two lead pins. These components are preferred in certain applications, as they are easier to mount and provide better overall performance due to their larger size.

Advantages of the 36501E47NJ

The 36501E47NJ fixed inductor provides many advantages to its users. It is a surface mount device, which helps reduce the overall size and requires fewer mounting steps than through-hole devices. It has a wide operating temperature range (-40°C to 125°C) and can be used in various applications such as automotive, industrial, and consumer electronics. The device also offers superior performance with a low ripple current up to 3.0A. The inductance rating remains stable even when operating over the maximum temperature range.

Disadvantages of the 36501E47NJ

The 36501E47NJ fixed inductor also has some disadvantages. The device is fairly sensitive to EMI/RFI and may not be suitable for high-frequency applications. It has a relatively high temperature coefficient, which means that its inductance rating may be affected by changes in the operating temperature. The maximum operating frequency is also limited to 250kHz.

Conclusion

The 36501E47NJ fixed inductor device is an important component in power supply designs for many different applications with a wide temperature range. The device has many advantages, such as its small size, low ripple current, and stability performance. However, it also has some drawbacks, such as its sensitivity to EMI/RFI and its limited operating frequency. In the end, this particular fixed inductor will depend on the application and requirements of the user to determine suitability.
