Fixed Inductors

Inductors are passive electronic components, consisting of a conductor shaped as a coil with an electric current that runs through it. This current creates a magnetic field, so in the case of an inductor the electrons that are passing through its coil will create a current consisting of hundreds of different magnetic “slices”.

When resistance is applied to the inductor, it combines the magnetic fields of the slices and produces an induced polarization that opposes the change in current. This results in opposing change in electric potential and creating an electrical energy storage device, which is called inductance, hence the name inductor.

The 1008R-681F fixed inductor is a two-terminal non-polarized CMOS device that features low DCR (self-resisting force), small size, low internal resistance, and high frequency charactiction. It is typically used as a DC blocking capacitor, RF choke, or low-impedance power line filter in many communication and power supply applications.

The 1008R-681F is designed using an advanced thin-film, ceramic substrate, and multilayer metalization technology, meaning that it is highly durable and reliable while having exceptionally low parasitic capacitance and inductance. Its construction and precise matching of physical dimensions allow it to have a high Q-factor, high amount of current, and low internal resistance. As an added bonus, this fixed inductor is extremely efficient and offers high power performances.

The working principle of the 1008R-681F is simple. First, the applied current interacts with the core of the device, which induces a magnetic field. This magnetic field is then transferred to the surrounding environment, and the same magnetic field is potentiated by the secondary coil within the device. This then induces an opposite imaginary current that counteracts the original current, effectively dissipating it into the surrounding environment.

The 1008R-681F is ideal for applications such as high-speed signal transmission, power supply noise reduction, RF EMI reduction, motor drive circuits, and interference suppression. Its superior EMI filtering performance makes it suitable for a wide range of portable communications devices, video and audio systems, and other high-end digital products.

The 1008R-681F fixed inductor from Sunnydene is an ideal choice for various designs that require high performance and quality. It is easy to use, cost-efficient, and offers reliable performance even in challenging environments. Additionally, it is extremely durable and guarantees minimal resistance to current. As such, it is an ideal choice for many applications including those listed above.
