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 400 mW at + 70 °C
• Load life stability: to 0.01 % at 70 °C, 2000 h
at rated power
• Resistance range: 10 Ω to 125 kΩ (for higher and lower
values, please contact us)
Top View
• Vishay 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)
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.
• Fast thermal stabilization < 1 s
• Electrostatic discharge (ESD) up to ꢀ5 ꢂꢂꢂ V
• Short time overload: ≤ 0.01 %
• Non inductive, non capacitive design
• Rise time: 1 ns effectively no ringing
• Current noise: - 42 dB
• Voltage coefficient < 0.1 ppm/V
• Non inductive: < 0.08 µH
The BMF provides an inherently low and predictable
Temperature Coefficient of Resistance (TCR) and excellent
load life stability for high precision analog applications.
• Non hot spot design
• Terminal finishes available: lead (Pb)-free, tin/lead alloy
• Compliant to RoHS directive 2002/95/EC
• Matched sets are available per request
• Prototype quantities available in just 5 working days
or sooner. For more information, please contact
foil@vishaypg.com
Model VSM 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.
The VSM has a full wraparound termination which ensures
safe handling during the manufacturing process, as well as
providing stability during multiple thermal cyclings.
• For better performances please review VSMP and
VFCP Series datasheets
Our application engineering department is available to
advise and make recommendations. For non-standard
technical requirements and special applications, please

A low profile solder fillet is
recommended to avoid unnecessary
stresses along top edge of
metallization. IR and vapor phase
reflow are best.
Notes
(1)
Avoid the use of cleaning agents which could attack epoxy resins, which form part of the resistor construction
Vacuum pick up is recommended for handling
Soldering iron may damage the resistor
