Fixed inductors, also known as chokes or coils, are components used in electronic circuits that are capable of providing a wide range of inductance values. The 3090R-100K is one of the more popular fixed inductors available and with its many benefits, it’s easy to understand why. This article will provide an overview of the application field and working principle of the 3090R-100K.

The 3090R-100K is an inductor designed for use in AC switching power supplies, as a broadband filter, or as an EMI filter. It has a wide operating temperature range of -55°C to +125°C and a wide operating voltage range of 10VDC to 100VDC. It is available in both through-hole and surface mount packages, allowing for easy installation and versatility in circuit design. Its low profile design makes it ideal for applications where space is limited.

In terms of its working principle, the 3090R-100K is based on the principle of self-inductance. This means that when current passes through the inductor, a magnetic field is generated, which then induces an opposing voltage in the inductor, creating a counter-current. This counter-current acts to limit the flow of current, thus effectively restoring balance in the circuit. This type of inductor is commonly used as a noise filter, or an energy storage device, in electronic circuits.

The 3090R-100K is a great choice for applications where high interference levels are a concern. The high inductance value allows for greater filtering capabilities, meaning that it can effectively reduce interference and reduce signal distortion. It also has a higher voltage rating, meaning that it can handle more voltage without failing. As well as being used in AC switching power supplies, the 3090R-100K can also be used in multi-stage amplifier circuits, and is often used in ham radios.

Due to its many advantages, the 3090R-100K is a popular fixed inductor choice. It provides a wide range of inductance values, and is suitable for a variety of applications. Because of its wide temperature range, low profile design, and higher voltage rating, it is well-suited for applications requiring a high level of performance. Its self-inductance principle means that it can act as a filter, energy storage device, and a noise filter, making it an ideal choice for EMI filtering or HAM radio applications.
