TDK Corporation Industry's First(a) Low Varistor Voltage 6.8 V Multilayer Chip Varistor Launched

Business Wire
TDK Corporation announced today that it has developed the
AVRM0603C6R8NT101N (0.6 mm � 0.3 mm � 0.3 mm) multilayer chip
varistor with low varistor voltage of 6.8 V. Mass production will
begin in June. The AVRM0603C6R8NT101N boasts the industry�s lowest
varistor voltage for a multilayer chip varistor and is also the
industry�s smallest varistor of its type. Mobile electronic devices
such as mobile phones and portable music players are being made
ever smaller even as they incorporate more advanced functions, and
consequently, the miniaturization and high-density integration of
components is progressing rapidly. In addition, the shift to lower
voltages for operating ICs is also accelerating to reduce power
consumption and maintain and extend operating times. In conjunction
with these developments, the risks of malfunctions from static
electricity at lower voltages than previously are increasing, and
consequently, protective components with both low varistor voltage
and compact size are needed as countermeasures. In response to this
demand, TDK improved multilayer chip varistor materials and
internal structures to reduce varistor voltage to 6.8 V. As a
result, the static electric limiting voltage has been reduced from
the 8 V varistor voltage of earlier products to 6.8 V, a reduction
of 15%. Because the varistors are compact and have no polarity,
they contribute to reductions in both mounting area and mounting
costs, making them ideal static electric countermeasures in compact
mobile devices. (a) As of June 2007, according to TDK
