Fixed Inductors are components used in various electronic devices and circuits, offering high frequency filtering and impedance matching. The 1945-04J Inductor has been widely used in the industry for its low profile and superior performance. This inductor is an important component in controlling the flow of electricity within a circuit, and can be used to create inductor-style filters and high frequency waveforms.

The 1945-04J Inductor is a cylindrical inductor with four leads for attaching to a PCB. It measures 3.2mm high by 3.2mm wide and has a height of 0.7mm. The inductance of this inductor is specified as 0.27μH (microhenries) which indicates a low inductance value. The operating temperature range for this inductor is from -40°C to 85°C, which means it can be used in wide range of temperatures.

The working principle behind the 1945-04J Inductor is based upon the fact that current in an inductor creates a magnetic field within the inductor. When the current changes the magnetic field, energy is stored in the form of an electric field and this energy is transferred back into the current when the field collapses. As a result, current in an inductor lags the voltage by 90 degrees, which can produce a low pass filter.

The 1945-04J Inductor is a great choice for applications which require a low-profile device with a high inductance value. It is most commonly used in Filter circuits and Amplifier circuits, where it is used to reduce high frequency frequency signals and reduce noise. It can also be used in switched-mode power supplies, to help control the current in the circuit. It is also used in Resonant circuits to tune a circuit for specific frequencies, and in RF circuits.

The 1945-04J Inductor is a great choice for electronics engineers who are looking for a reliable and effective inductor to use in their projects. This inductor offers superior performance and reliability for a wide range of applications, and its low profile design ensures that it can be used in many tight spaces. Its high inductance value and relatively low operating temperature make it an ideal choice for many applications.
