FRSH Series (Z1 Foil Technology)
0603, 0805, 1206, 1506, 2010, 2512
INTRODUCTION
Vishay Foil Resistors (VFR) introduces a new line of Ultra
Precision Bulk Metal
®
Z1 Foil Technology: wraparound
surface mount chip resistors with extended pads for high
temperature up to + 225 °C
(1)
(working power: to 330mW at
+200 °C).
The new extended pad designs also exhibit better heat
di
ssipation, thus enabling higher power usage (Working
Power: to 1200mW at + 70°C
(1)
). The FRSH has a full
wraparound termination that ensures safe handling during
the manufacturing process, as well as providing stability
during multiple thermal cyclings.
The FRSH 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
