Description

How it behaves

  •  

What do Current Transformers aim to solve

  •  

  • AC circuit filter → attenuate high frequency noise, in series with current pathway, from harmonics in AC current → “AC choke” or “ AC power choke”
  • Maintain inductance over specified frequency range
+ Low parasitic capacitance → High self-resonant frequency > 5MHz *

* High inductance or inductors with many turns → lower self-resonant frequency
