Fixed inductors are electronic components used in a circuit to provide a relatively steady current over a period of time. Fixed inductors are typically used in applications such as power supplies, where an input voltage is applied to the inductor and the inductor provides a steady output current. The 3094-820KS is an example of a fixed inductor that has been designed for use in high frequency applications such as radio frequency (RF) amplifiers, and it is capable of handling both low and high voltage loads.

The 3094-820KS is a surface mount fixed inductor that is made with high temperature, shielded ceramic core material. It features a low profile design, with a small footprint, and a small coil capacitance. The 3094-820KS can operate over a wide temperature range from -55° to +150°C. It also has an operating frequency range of 5kHz to 8GHz, making it suitable for many high frequency applications. Its inductance is rated at 0.08µH (microhenry) with an inductance tolerance of ±20%. The internal construction of the inductor consists of copper wire wound on a three-layer ceramic core.

The 3094-820KS has a number of features that make it ideal for use in RF applications, including a high power handling capability (up to 15W), and a low ESR (equivalent series resistance) of 8mΩ. It is also shielded to minimize unwanted interference, and it features a high shielding factor of >65dB. Additionally, the 3094-820KS has a high Q rating of 24, which ensures that inductive losses are minimized. The 3094-820KS is also RoHS (Restriction of Hazardous Substances) compliant.

In terms of its application field, the 3094-820KS is ideal for use in a range of high frequency applications, including cellular phones, wireless communication systems, antennas, RF amplifiers, receivers, and transmitters. It can also be used in power converter circuits and automotive electronics for boosted chip capabilities. Its design makes it particularly suitable for high frequency RF circuits that require high power handling capability, and/or a small physical size.

The working principle of the 3094-820KS is based on the principle of inductance. An inductor is an electrical component that stores energy in the form of a magnetic field when a current is passed through it. When the current in the inductor is changed, the magnetic field generated by the inductor produces a voltage that is proportional to the rate of change of the current in the inductor. This voltage, in turn, opposes the change in current, creating what is known as inductive reactance. This reactance is important in high frequency applications, as it helps reduce unwanted signals and ensure that signals remain within the desired frequency range.

In summary, the 3094-820KS is a fixed inductor that is designed for use in high frequency RF applications. It features a high power handling capability, a low equivalent series resistance, and a high shielding factor. It is also compliant with RoHS standards. The 3094- 820KS is suitable for use in RF amplifiers, receivers, transmitters, antennas, and automotive electronics, among other applications. Its working principle is based on inductance, where a magnetic field is created when an alternating current is passed through the coil, resulting in an inductive reactance which helps to reduce interference and ensure signals remain within the desired frequency range.
