The resistance of the inductor to DC is almost zero.
电感器可能体积庞大,笨重且昂贵,因此用便宜的元件代替它们通常很有价值。
Inductors can be bulky, heavy, and expensive, so it is often valuable to replace them with cheaper components.
当高频信号通过电感器时,它遇到很大的电阻并且难以通过。
When a high-frequency signal passes through an inductor, it encounters a large resistance and is difficult to pass.
典型的无源元件有:电阻器、电感器、电容器和变压器,而它们是构建任何电子或电气电路所必需的。
A typical passive component would be: resistors, inductors, capacitors and transformers which together are required to build any electrical or electronic circuit.
我们从前面的关于电感器的教程中知道,电感器是能够以磁场的形式存储能量的器件。
We know from the previous tutorial about the inductor, that inductors are devices that can store their energy in the form of a magnetic field.
所示单元恰好是早期无线电工作中使用的空芯电感器。
The unit shown happens to be an air-core inductor used in early radio work.
将继续推出晶体,振荡器和电感器,以满足其客户对这些技术的需求。
Will continue to introduce crystals, oscillators, and inductors to meet the requirements its customers demand for these technologies.
对于接地连接,切一块柔性(绞合或电感器)连接至4.5厘米长。
For the ground connection, cut one piece of flexible(litz or inductor) wire to a length of 4.5 cm.
电感器在电子制作中虽然使用得不是很多,但它们在电路中同样重要。
Inductors are not used much in electronics, but they are equally important in circuits.
许多电感器在线圈内有一个由铁或铁氧体制成的磁芯,用于增加磁场,从而增加电感。
Many inductors have a magnetic core made of iron or ferrite inside the coil, which serves to increase the magnetic field and thus the inductance.
The SWIFT TPSM84A21 and TPSM84A22 DC/DC modules integrate power MOSFETs,shielded inductors, input and output capacitors, and passives into a tiny, low profile footprint.
