Pulse Withstanding
Chip Resistors
PWC Series
Today’s electronic devices are becoming
smaller and smaller. As a result designers
are moving more towards surface mount
components not only for new designs
but also to design out large axial and
other through-hole resistors. In most
cases this is a straightforward task as
several resistor manufacturers offer chip
resistors with performances to match
axial parts. However in some cases, due
to power rating or pulse withstanding
requirements, this has been impossible.
The requirement, in particular, for pulse
withstand capability is growing due to
the need to protect sensitive modern
electronic systems.
To meet this demand TT electronics have
designed a Pulse Withstanding Chip
Resistor (PWC Series). The PWC series is
available in four standard sizes from
0805 to 2512 as shown in the following
table. The table also gives details of the
improved LEV (Limiting Element Voltage)
and increased power rating. Pulse
withstanding details are given on the
following pages.
The enhanced performance of the chips
is made possible by the precise use of
the best resistance inks and a closely
controlled production process.
