Fixed Inductors

Inductors are a type of electronic component used in a wide range of electronic circuits. They areused to store and control energy and can be found in a variety of different electrical appliancesand devices, from simple consumer electronics to complex computer systems. Inductors provideelectrical impedance and are most commonly used in alternating current (AC) applications.

PA3784.151HL is one example of a fixed inductor. It is a small surface mount device with anoperating temperature range of -20 to +85 degrees Celsius. It is designed to provide inductance inan AC signal over the frequency range 0.1 MHz to 1.0 GHz. The device has an impedance of 25.1Ohms ± 0.3 Ohms at 100 MHz, and a minimum self-resonant frequency of 3.0 GHz.

Applications

Due to its size and frequency range, the PA3784.151HL can be used in a wide variety ofapplications, including but not limited to:

• Radar circuitry
• Cable and satellite systems
• Amplifier circuitry
• Radar detectors
• High-frequency communication systems
• High-frequency radio systems
• Radar navigation systems
• High-frequency power supplies

Working Principle

An inductor works by creating a magnetic field when an electrical current passes through it. The magnetic field creates oppose the change of current, which creates a force that is directly proportional to the rate of change of current. This means that the inductor opposes any change in the electrical current, and so acts as a filter to reduce electrical noise in a circuit. This makes the PA3784.151HL suitable for applications where low electrical noise is desired, such as high frequency radio systems.

In addition, the PA3784.151HL has a high self-resonant frequency. This means that it can pass a wide range of frequencies without attenuating the signal too much. This makes it suitable for applications such as radar navigation systems, where a wide frequency range needs to be passed without too much signal loss.

Conclusion

The PA3784.151HL is a fixed inductor that can be used in a wide range of applications due to its small size and high self-resonant frequency. It is designed to provide inductance in an AC signal over the frequency range 0.1 MHz to 1.0 GHz. The device has an impedance of 25.1 Ohms ± 0.3 Ohms at 100 MHz, and a minimum self-resonant frequency of 3.0 GHz, making it a suitable choice for high frequency applications where low electrical noise is desired.
