Resonance

A natural vibration is caused by an external stimulus. There are mechanical ones and electrical ones.
"Objects" have a natural frequency due to their mass and size, and especially when an external stimulus matches this natural frequency, resonance is likely to occur.
On the other hand, at the frequency where the inductance and capacitance exactly cancel each other electrically, the element impedance becomes extremely small and resonance occurs.
Also, due to reflections at multiple points on the transmission line, resonance occurs at frequencies in which the reflected waves reinforce each other, and this is used as an antenna. In unintended cases, it can also be a source of noise (receiving source).

We have Z-Move structure series connectors for vibration countermeasures. We also provide support for vibration analysis, etc., upon customer request.
