INTRODUCTION
Vishay Foil Resistors (VFR) introduces a new line of Ultra
Precision Bulk Metal
®
Z1-Foil technology: hybrid chip
resistors, connected using gold wire bonding. The HTHG
series features two different layouts of chip designs
according to the sizes (see figure 3 and table 4). 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 HTHG 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
