Fixed inductors are electronic components that remain constant in their inductance, or ability to induce a current with an applied voltage. The 0819R-48F is a particularly efficient and small size fixed inductor with a variety of applications. The 0819R-48F is especially suitable for filters in RF, IF (intermediate frequency) amplifiers, and antenna systems as it has a relatively high inductance and low loss.

The 0819R-48F is radial, through-hole type inductor with its core body being ferrite and its cover body being both a plastic resin and an enameled copper wire. Its main characteristics are its size; 8.0×19.0 mm, its inductance of 48uH, its rated current of 11.5A, withstanding voltage of 400VDC, and its resonant frequency of 44MHz.

The 0619R-48F has three primary working principles; inductance, resistance, and capacitance. Its inductance allows it to store electrical energy in a magnetic field, its resistance dissipates energy in the form of heat, and its capacitance provides low impedances over certain ranges of frequency. This combination of characteristics allows the 0619R-48F to filter out certain frequencies whilst allowing others to pass through a device or system.

The magnetic core of the 0619R-48F can take on either a toroidal, cylindrical, or barrel shape, depending on the application requirements. The core serves to concentrate the magnetic field and increase the inductance value of the inductor, as well as providing a cool operating environment and increased product reliability. Additionally, the enameled copper wire helps to reduce heat loss and the plastic resin increases its resistance to dust and water.

The primary application fields of the 0619R-48F include both RF and IF amplifiers, as it can eliminate or attenuate unwanted frequencies and limit the signal levels while allowing the desired frequency range to pass. It can also be used in audio and video applications as an antenna to limit unwanted interference. As it is very small and has a wide range of usable frequencies, the 0619R-48F can also be used in other applications, such as medical devices and telecommunications.

The 0619R-48F is a versatile and efficient fixed inductor that has a variety of applications. Its high inductance and low loss allow it to be used in RF and IF applications where it can attenuate or eliminate unwanted frequencies. Its small size also makes it suitable for use in a range of applications, from audio systems to medical equipment. As such, the 0619R-48F demonstrates the effectiveness of fixed inductors in providing reliable filtering and signal manipulation.
