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
