Chip Capacitors Find Their Range Extended

The Inter-Digitated Capacitor (IDC) line of chip capacitors now includes an 0612-size chip with a higher capacitance value than previously offered in the series. The device offers 2.2 µF at 6.3V in a X7R dielectric. Moreover, the capacitor sports low inductance of just 175 pH. The IDC line of chip caps is suited for decoupling signal lines for today's ever-faster CPUs.The devices work by connecting the chips' single capacitor with a series of eight vias to the power and ground planes in an alternating (or inter-digitating) pattern. This internal construction geometry alternates the polarity of these elements, allowing the alternating inductance values to cancel each other.
