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.
