Fixed inductors, often referred to as chokes or coils, are electrical components that are designed to store energy in the form of an electromagnetic field. The 1945R-03K is a type of fixed inductor, specifically a radial-leaded, shielded, molded RF choke series. Its main application fields are broadband wireless, ISM / RFID, satellite, Modem, VCR, home theatres, CATV, etc.
The 1945R-03K is designed with a ferrite core and a F07-43N ferrite core material construction. It features a high shielded, low profile package which gives it high thermal resistivity. The operating temperature range of the 1945R-03K is between -40℃ and +85℃, a storage temperature of -25℃ to +85℃ and a maximum operating voltage of 40V. It has a rated current of 8 mA and an inductance of 0.3μH.
The 1945R-03K has two different working principles that allow it to be used in a variety of applications. The first working principle is based on inductance. In this case, the inductor works by creating a magnetic field when current is passed through it. This magnetic field is then used to induce a voltage across the inductor. The second working principle is based on resistance. In this case, the inductor works by restricting the flow of current in the circuit. This creates a resistance to the current which allows the inductor to act as a filter.
The 1945R-03K is used in a variety of applications, ranging from consumer electronics to industrial applications. In consumer electronics, the 1945R-03K is used to prevent interference and to limit electrical noise. It can also be used to increase power efficiency and to reduce power consumption. In industrial applications, the 1945R-03K is used to provide current feedback, to provide filtering, to provide noise suppression, to provide voltage regulation, and to provide EMI/RFI protection.
The 1945R-03K is a reliable and versatile component. Its unique combination of ferrite core and F07-43N ferrite core material make it perfect for a variety of applications. It is also easy to install and can operate at a high temperature range. It is an ideal choice for those looking for a fixed inductor that offers reliability, high performance, and flexibility.
