Features

• Three Terminal EMFIL Capacitors, DSN6 / DSN9 / DST9N Series. Unlike conventional two terminal capacitors which have high residual inductance within the lead wires, thereby impeding the path of high frequency noise to ground, a three terminal capacitor forms a T-filter providing high inductance in series with the line, via two integral ferrite beads, and low inductance to ground via the bypass capacitor. Thus they provide increased attenuation with frequency over conventional decoupling capacitors. Note: See 'key characteristics' table for details of effective frequency ranges. Applications include:. High frequency noise suppression for d.c. power lines Noise suppression in digital high impedance circuits Noise suppression in high speed digital signals (clocks etc.) Noise suppression in video IF signals
