Läpikytkentäkomponentit

Läpikytkentäkomponentit, often translated as feedthrough components or feedthrough capacitors, are passive electronic components designed to pass specific signals while blocking others. Their primary function is to suppress unwanted high-frequency noise or radio frequency interference (RFI) from entering or leaving a system. They achieve this by acting as a low-pass filter.

These components are typically installed in a panel or chassis, providing a clean connection point for signals to pass through while simultaneously filtering out noise. The construction usually involves a capacitor integrated into a feedthrough structure, often with a bolt or threaded stud for mounting. The capacitive element is connected between the signal conductor and the ground plane of the enclosure.

Läpikytkentäkomponentit are crucial in applications where electromagnetic compatibility (EMC) is a concern. This includes sensitive electronic equipment, communication systems, medical devices, and military applications. By filtering out noise, they ensure the integrity and reliability of signal transmission, preventing malfunctions and improving overall performance. They are available in various capacitance values and voltage ratings to suit different filtering requirements and operating conditions.
