Фиксированные катушки индуктивности

An inductor, also known as a coil, choke, or reactor, is a passive two-terminal electrical component that stores energy in a magnetic field when electric current flows through it. When the current changes, the magnetic field induces a voltage in the conductor. The induced voltage has a polarity which opposes the change in current that created it. The unit of inductance is the Henry (H). Mounting options include surface, through-hole, and chassis.
