Vishay Foil Resistors
Bulk Metal® Foil Technology Low Profile Conformally Coated High
Precision Resistor with Tight Tolerance from ꢀ0ꢀꢁ ꢂ and Load Life
Stability of ꢀ0ꢀꢁ ꢂ and Instantaneous Thermal Stabilization
FEATURES
• Temperature coefficient of resistance (TCR):
2.0 ppm/°C typical (- 55 °C to + 125 °C,
+ 25 °C ref.) (see table 1)
• Tolerance: to 0.01 %
• Power rating: to 300 mW at + 70 °C
• Load life stability: to 0.01 % at 70 °C, 2000 h at rated
power
• Resistance range: 5 Ω to 120 kΩ (for higher and lower
values, please contact us)
INTRODUCTION
Bulk Metal® Foil (BMF) technology out-performs all other
resistor technologies available today for applications that
require high precision and high stability, and allows
production of customer oriented products designed to satisfy
challenging and specific technical requirements.
• Vishay Foil resistors are not restricted to standard values;
specific “as required” values can be supplied at no extra
cost or delivery (e.g. 1K2345 vs. 1K)
• Thermal stabilization time < 1 s
• Electrostatic discharge (ESD) up to 25 ꢀꢀꢀ V
• Short time overload: ≤ 0.01 %
The BMF provides an inherently low and predictable
Temperature Coefficient of Resistance (TCR) and excellent
load life stability for high precision analog applications.
• Maximum working voltage: 300 V
• Non inductive, non capacitive design
• Rise time: 1 ns effectively no ringing
• Current noise: < - 42 dB
Model VSH offers low TCR, excellent load life stability, tight
tolerance, excellent shelf life stability, low current noise and
low voltage coefficient, all in the same resistor.
Our application engineering department is available to
advise and make recommendations. For non-standard
technical requirements and special applications, please
contact us using the e-mail address in the footer below.
• Voltage coefficient < 0.1 ppm/V
• Non inductive: < 0.08 µH
• Non hot spot design
• Terminal finish: lead (Pb)-free or tin/lead alloy
• Matched sets are available per request
• Compliant to RoHS directive 2002/95/EC
