SMD Chip Inductor, as the core passive component in electronic
circuits, undertakes multiple key functions with its compact chip
design and efficient electromagnetic characteristics
1. Noise filtering and signal purification: By blocking the
characteristics of high-frequency alternating current, it
effectively filters high-frequency noise and electromagnetic
interference (EMI) in circuits, especially in audio circuits and
communication modules, which can reduce signal distortion and
ensure the clarity of audio and data transmission.
2. Current stability and ripple suppression: In power circuits
(such as DC-DC converters and fast charging modules), the
characteristic of inductance "obstructing current changes" is
utilized to smooth current fluctuations, suppress output voltage
ripple, and provide stable DC power supply for sensitive components
such as chips and sensors.
3. Energy storage and release: In high-frequency switch circuits,
temporary energy storage and release are achieved through magnetic
field energy storage, combined with capacitors and other components
to form a filtering network, improving power conversion efficiency.
This is commonly used in fast charging circuits for smartphones and
laptops.
4. Impedance matching and signal coupling: In RF circuits and
antenna modules, impedance between different circuits is matched by
adjusting inductance values to reduce signal reflection loss and
ensure efficient transmission of wireless and high-frequency
signals; At the same time, signal coupling between circuits can be
achieved, isolating DC components and only transmitting AC signals.
