Fixed inductors are electronic components that store energy in the form of magnetic fields and are widely used in a variety of applications. The 1945R-07F is a type of fixed inductor with specific properties which make it suitable for certain applications and electronic circuits.
The Construction of the 1945R-07F
The 1945R-07F is coiled around a ring-shaped ferrite core and is made of insulated copper. Its size is 0.313” long and 0.153” in diameter, and it is encased in an epoxy dome which helps to protect from changes in external temperature and humidity. Its inductance is 2.2µH with a tolerance of 5%, and its DC resistance is 125mΩ with a tolerance of 10%. It is rated for a maximum DC current of 150mA and can withstand temperature changes from -40°C to +80°C.
The Applications of the 1945R-07F
The 1945R-07F is primarily used as a noise filter for circuit protection, particularly in low current circuits. Its properties make it useful as an inductor for noise suppression, as it is able to withstand high temperature and sudden changes in ambient temperature and humidity while still operating effectively. In this regard, it is often found in circuits that require protection from radio frequency interference (RFI) and electromagnetic interference (EMI) noise.
In addition to noise suppression, the 1945R-07F can also be used as a transient suppressor. Car audio systems which contain capacitors and voltage regulators may require additional transient protection using the 1945R-07F. It can also be used in other audio circuits such as waveguides and power amplifiers.
The Working Principle of the 1945R-07F
The 1945R-07F works by creating a magnetic field which is proportional to the current running through the inductor. When a current is passed through the 1945R-07F, the magnetic field will obstruct the current flow, and this magnetic field is also able to filter out any unwanted noise in the circuit. As a result, the circuit is protected from any sudden and undesirable changes in voltage.
The 1945R-07F also works to maintain a constant voltage level in the circuit by regulating the current flow. By regulating the current, the inductor can reduce the level of voltage spikes or sudden changes in voltage caused by external noise. This helps to ensure the circuit does not become damaged by high voltage.
Conclusion
The 1945R-07F is a type of fixed inductor specifically designed for use in audio circuits. It is used primarily for protection from radio frequency interference (RFI) and electromagnetic interference (EMI) noise, as well as for transient protection. It works by creating a magnetic field which is proportional to the current running through the inductor, which in turn filters out unwanted noise and reduces voltage spikes.
