Ultra High-Precision Foil Wraparound Surface Mount Chip Resistor
Ultra High-Precision Foil Wraparound
Surface Mount Chip Resistor
with Gold Plated Terminals for High Temperature Applications up to +225°C
FEATURES
• Temperature coefficient of resistance (TCR):
2.5 ppm/°C max (–55°C to +200°C, +25°C ref.)
• Resistance range: 10 Ω to 125 kΩ (for higher and lower
values, please contact us)
• Resistance tolerance: to ±0.01%
• Working power
(1)
:
to 750 mW at +70°C
to 300 mW at +200°C
• Long-term stability: 0.1% at +225 °C for 1000 h,
no power
• Load-life stability: ±0.1% at 200°C for 2000 h, at
working power
• Bulk Metal Foil resistors are not restricted to standard
values; we can supply specific “as required” values at
no extra cost or delivery (e.g., 1K2345 vs. 1K)
• Thermal stabilization time <1 s (nominal value achieved
within 10 ppm of steady state value)
• Electrostatic discharge (ESD) at least to 25 kV
• Non-inductive, non-capacitive design
• Rise time: 1 ns effectively no ringing
• Current noise: 0.010 μV
RMS
/V of applied voltage
(<–40 dB)
• Voltage coefficient: 0.1 ppm/V
• Non-inductive: <0.08 μH
• Non hot spot design
• Terminal finish: soft gold plating

INTRODUCTION
Vishay Foil Resistors (VFR) introduces a new line of Ultra
Precision Bulk Metal
®
Z1 Foil Technology: wraparound
surface mount chip resistors with gold-plated terminals
for high temperature up to +225°C
(1)
(working power: to
300 mW at +200°C).
The FRSG series incorporates Z1 Foil Technology
to extend its critical performance features to high-
temperature environments, while maintaining the same
low TCR. The gold-plated terminals support the use of
popular mounting methods used in the industry, therefore,
facilitating any design considerations required.
The FRSG 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
