Typically, the equivalent circuit for these filters is one of the "Lumped Constant Circuit" type where a by-pass capacitor is used in conjunction with an inductor. See Figure 2. The new "DCT" noise filters (SEMIFILT) are unique in that they employ a "Distributed Constant Circuit" type where the capacitance and inductance are combined to form an integrated capaci- tive/inductive circuit as shown in Figure 1. When conventional noise filters (Lumped Constant type) are not achieving sufficient noise reduction,our SC series can directly replace these filters without any adverse effects on circuit characteristics. SEMIFILT SC series are available in several series,each covering various frequency ranges. SEMIFILT SC series have also shown excellent protection against EMI noise from various external electronic appliances. SEMIFILT SC Noise Noise - fig. - fig. Conceptual Structure of SC/SP Series SC L C DCT noise filters (SEMIFILT SC Series)are constructed by winding two conductors with an interlayer of dielectric material. High attenuation characteristics are achieved by continuous integration of the L and C. LFC R Dielectric Conductor Conductor Dielectric Via Hole Conductor LFC R Directional Noise Reduction Effect (Bypass effect) High frequency noise injected through terminal generates an electromotive force. Due to the proximity of the ground connection, line responds as a bypass capacitor and shunts the unwanted noise to ground. (Inductor effect) In the alternate case, when a high frequency noise is injected into terminal , the bypass effect is decreased. This is due to the fact that line at its terminated end is responding more as an inductor, with less bypass capacitance. The high frequency noise is attenuated by the inductive effect of the main line itself.
