role
Eliminating high-frequency noise: Loop inductors are high-quality inductors that can eliminate high-frequency noise. When a high-frequency signal passes through a coil, the annular magnetic core converts the frequency of the signal, converting the high-frequency signal into a low-frequency signal, thereby achieving the effect of eliminating noise.
Filtering: Loop inductors can be an important component of filters, which selectively amplify and attenuate signals to achieve the purpose of filtering, thereby making signals clearer and more accurate.
Generate periodic signals: Loop inductors can serve as important components in oscillators, dissipating a portion of energy from the circuit to cause self-excited oscillations, resulting in periodic signals such as sine waves.
Adjusting current and voltage: In a constant current source circuit, a ring inductor is used as an impedance to adjust the magnitude and direction of the output current, thereby achieving a constant current output. In transformers, toroidal inductors are also commonly used to adjust the output voltage by adjusting the magnitude and direction of the current.
purpose
Filter: Loop inductors have the ability to resist high-frequency interference and are widely used in filters in high-frequency circuits to reduce circuit noise and interference.
Antenna: A circular inductor can be used as part of an antenna to convert radio signals into current signals.
Sensor: Loop inductors can be used as components in sensors to measure parameters such as current and voltage.
Magnetic memory: Loop inductors can be used as components in magnetic memory to store and read data.
Electromagnetic compatibility design: Loop inductors can enhance the anti-interference ability of devices, reduce radiation to external electromagnetic fields, meet strict electromagnetic compatibility standards, and enable electronic devices to operate stably in various complex electromagnetic environments.
In summary, ring inductance is a common component in circuits, especially in high-frequency circuits. Ring inductance can play a more diverse application role, such as eliminating high-frequency noise, impedance adjustment, current stability, etc., playing an important role in ensuring the correct operation of the circuit.
