quantities
The internal structure furnishes a reduced inductance when
compared to that of a conventional capacitor. This is a result
of the novel internal electrode structure which inherently
reduces the inductance by the cancellation effect of opposing
currents in close proximity. The capacitance line to ground
(common mode) is closely matched due to the symmetry
within the design. As the device includes line to ground
capacitance for both lines, any temperature, ageing and
voltage effects will have an equal influence on both lines
therefore maintaining balanced decoupling.
Because the part acts as a de-coupling device, the current
limitations of a standard 3 terminal chip do not apply. The
single line 3 terminal feedthrough chip carries the signal
current through the very thin feedthrough electrodes within
the device which have limited dc resistance and so can cause
excessive heating, hence the maximum permissible current
is often limited to around 300mA for a 1206 device. The
Integrated Passive Component is in by-pass across two lines
and so is unaffected by high signal currents.
The table below offers a comparison of de-coupling devices
and demonstrates how the Integrated Passive Component
extends the options for EMC circuit protection.
