High Current 470M Wirewound Chip Inductor 47UH SMD Power Inductor
1.Product Description
The 470M Wirewound Chip Inductor is a wirewound chip inductor with
an inductance value of 470 microhenries (µH) for high frequency
circuits and power management systems. Features include high
inductance, low DC resistance, and excellent magnetic shielding to
suppress EMI and improve circuit stability. The inductors are
available in a compact SMD package design for easy automated
soldering and integration into a variety of PCB boards. Widely used
in switch-mode power supplies (SMPS), DC-DC converters, filters,
and energy storage circuits, they provide efficient energy storage
and transfer, and are an indispensable key component in electronic
devices.
2.Functionality
The 470M Wirewound Chip Inductor is a wirewound chip inductor that
plays a key role in a variety of circuits. Its main functions
include:
1. Filtering Function: With high inductance value, it can
effectively inhibit high frequency current passing. In power supply
circuits, it can filter out the high-frequency noise in the current
and provide a smoother and more stable DC power supply for
electronic devices. For example, in the power management module of
the cell phone, it can remove the high frequency interference
generated by charging or other circuit work, and guarantee the
normal operation of other parts of the cell phone.
2. Signal processing: In signal processing circuits such as radio
frequency (RF) circuits, it can be used to select signals of
specific frequencies. By combining with capacitors and other
components to form a resonant circuit, it can accurately select
signals in the desired frequency band and improve the accuracy and
stability of signal transmission. For example, in the wireless
communication module, it helps the equipment to accurately receive
and send wireless signals of a specific frequency.
3. Energy storage function: when the current passes through, it
will convert the electric energy into magnetic energy and store it;
when the circuit needs, it will convert the magnetic energy back
into electric energy and release it. In some circuits that need to
provide large current instantly, such as the flash circuit of a
camera, the 470M Wirewound Chip Inductor can release the stored
energy when the flash is turned on to ensure that the flash works
properly.
