Value
A choke coil is a coil component used to block signals in a specific frequency range and suppress noise in power and signal lines.
主な特徴
It allows direct current to pass through while blocking alternating current
It allows direct current to flow almost unimpeded, while blocking or attenuating alternating current (especially high-frequency components), and is used for noise removal and smoothing in power supply circuits.
Effective for noise removal
It can be inserted in series with power lines or signal lines to suppress high-frequency noise and prevent the intrusion of external noise.
Supports a wide frequency range
It can handle noise from tens of kHz to hundreds of MHz, and you can choose the material (ferrite core, iron powder core, metal composite, etc.) according to your application.
Lineup tailored to applications
We offer a lineup tailored to applications, including toroidal types and coil types.
