INTRODUCTION

Vishay Foil Resistors (VFR) introduces a new line of Ultra

Precision Bulk Metal

Z1-Foil technology: chip resistor for

hybrid circuits with aluminum wire bonding. These new types

of hybrid chips were especially designed for high

temperature applications up to + 240 °C

(1)

(working power: to

150mW at + 220°C), and include gold plated terminals.

The HTHA series is available in any value within the

specified resistance range. VFR's application engineering

department is available to advise and make

recommendations.

For non-standard technical requirements and special

applications, please contact
