Fixed inductors are inductors that are designed to offer a static inductance, typically in a range of microHenes (uH) to milliHenes (mH). Commonly used in RF (radio frequency) applications as well as digital circuit, fixed inductors can present a variety of characteristics, like temperature tolerance, saturation current and voltage ratings and more. The 3094R-473HS Fixed Inductors are specially designed for high-frequency applications and provide superior performance. The inductor’s radio frequency characteristics include high Q/frequency characteristics, high self-resonant frequency (SRF), low cost and small size.

The 3094R-473HS Fixed Inductor is designed to be used in high frequency applications (for applications up to GHz frequencies), high voltage circuits and other applications where significant current is required. The inductance values of this device are 1.2 uH ±20% and its DCR values range from 0.42 to 0.54 Ohms. The magnetic core material is nonmagnetic iron powder which gives the inductor added stability. This inductor also features a superior electrical/mechanical design and provides extremely low thermal resistance.

In terms of application field, the 3094R-473HS Fixed Turn Inductors are extensively used in very high frequency mobile phones, RF boards, audio amplifiers, dc-dc converters, power supplies and pulse oscillators and more. They are especially useful when the inductance values between different elements in a circuit must match for proper operation. Other common applications include RF power amplifiers, VHF/UHF TV amplifiers, satellite receivers, oscillators and modulators.

The working principle of the 3094R-473HS Fixed Inductors lies in the fact that the inductor consists of a conductor (usually copper) wound on a magnetic core. An electrical current flows through the conductor, producing a magnetic field in the core material. This magnetic field induces an electrical voltage in the conductor, leading to the back-EMF generated in the core. This back-EMF is then dissipated as heat energy. Depending on the inductance and other factors, the current flows through the circuit determining the overall performance of the device.

Due to the high frequency performance, high current handling capability and extremely low thermal resistance, the 3094R-473HS Fixed Inductors are perfect for wide range of high-frequency applications. The combination of small size, low cost and high magnetic performance makes this device ideal for any design requiring superior performance in a small package. From medical devices to automotive electronics, the 3094R-473HS Fixed Inductors are designed to meet the highest standards of reliability and performance.
