EMI SUPPRESSION FILTERS
VARISTOR-CAPACITORS
3 -TERMINAL STRUCTURE
The reason the 3-terminal structure provides excellent
high frequency characteristics.
Bypass capacitors should logically be able to remove
more noise as frequency increases. In actual fact, the
electrodes and lead wires of the capacitor have series
inductance as shown in Fig. 3, and this causes an LC
resonance when the frequency is between 1MHz and
50MHz. As a result, when the frequency is higher than
the self-resonance frequency, the noise suppression
capability of the bypass capacitor is drastically reduced
because the capacitor functions as inductor. To solve
this problem, the DSS series has one side of the capacitor
electrodes connected to two lead wires. This eliminates
the series inductance to the capacitor. Furthermore,
a ferrite bead is attached to each lead wire to form a
T-shaped filter, thus providing efficient noise suppression.
