UP0.4UC-681-R

Fixed inductors are types of inductors that use a specific winding or core to produce a static inductance. The UP0.4UC-681-R is one of the most common fixed inductors used in a variety of different applications. When looking at the various applications and working principles of the UP0.4UC-681-R, it is important to understand what sets it apart from other inductors.

Application Field

The UP0.4UC-681-R is commonly used as a radio frequency interference (RFI) filter. In this application, it is used to reduce the effect of electromagnetic fields or radio signals on other electronic components around it. It has a capacitance rating of 0.4uF and a working frequency range of 1MHz-250MHz, making it well suited for use in RFI applications. Additionally, it is able to dissipate as much as 33 dB (fourth-order mode) of transmitted energy.

The UP0.4UC-681-R is also used for filter applications. In this application, it is used to reduce noise or unwanted signals in order to produce a clean radio frequency signal. It is commonly used as part of an image reject mixer filter in order to minimize unwanted signals and noise. Additionally, the UP0.4UC-681-R can also be used in audio frequency applications, such as in audio frequency transformers, where it is able to reduce the frequency of incoming signals.

Working Principle

The UP0.4UC-681-R is a type of fixed inductor and works on the principle of electromagnetic induction. When a current is passed through the inductor, it generates an electromagnetic field which creates a circular electric field around it. This electric field induces a current in the windings and core of the inductor, thus creating a secondary current. This secondary current is then amplified and passed onto the output side of the inductor.

One of the unique features of fixed inductors is that they are able to maintain a consistent inductance regardless of the frequency or voltage of the input signal. This makes them ideal for applications which require a consistent inductance over time. Additionally, the UP0.4UC-681-R is able to handle input currents up to 8.8A, making it suitable for even high-power applications.

Conclusion

The UP0.4UC-681-R is one of the most common types of fixed inductor used in a variety of applications. It is commonly used as an RFI filter, as part of an image reject mixer filter, and in audio frequency applications. Its ability to maintain a consistent inductance regardless of the frequency or voltage of the input signal makes it well-suited for these and other applications, while its high current rating makes it suitable for even high-power applications.
