INTRODUCTION
The 303134 through to 303138 series is the first surface
mount device to provide high rated power, excellent load life
stability along with extremely low TCR all in one resistor.
One of the most important parameters influencing stability is
the temperature coefficient of resistance (TCR). Although the
TCR of foil resistors is considered extremely low, this
characteristic has been further refined over the years. The
303134 through to 303138 Series utilizes ultra high precision
Bulk Metal
®
Z-Foil. The Z-Foil technology provides a
significant reduction of the resistive element’s sensitivity to
ambient temperature variations (TCR) and to self heating
when power is applied (power coefficient). Along with the
inherently low PCR and TCR, Z-Foil technology also
provides remarkably improved load life stability, low noise
and availability of tight tolerance.
The 303134 through to 303138 series has a full wraparound
termination which ensures safe handling during the
manufacturing process, as well as providing stability during
multiple thermal cyclings.
Our application engineering department is available to
advise and make recommendations.
