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.
•
Rise Time: 1 ns without ringing
• Current Noise: - 40 dB
• Voltage Coefficient < 0.1 ppm/V
• Non Inductive: < 0.08 µH
• Non Hot Spot Design
• Terminal Finishes Available: Lead (Pb)-free
The BMF provides an inherently low and predictable
Temperature Coefficient of Resistance (TCR) and excellent
load life stability for high precision analog applications.
Tin/Lead Alloy
• Matched sets are available per request
• Any value available within resistance range (e.g. 1K2345)
• Prototype samples available from 48 hours. For more
information, please contact foil@vishay.com
• For better performances please review VSMP and VFCP
Series datasheets
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.
