Discrete High Precision Surface Mount Chip Resistor
High Power - Excellent Long Term Stabilty
INTRODUCTION
VSMP1206 is the industry’s first device to provide higher
power rating with excellent long term stability along with
low nominal TCR of ± 0.5ppm/°C (-55°C to +125°C) all in
one.
The VSMP1206 Precision Surface Mount Chip Resistor
utilizes Ultra Precision Bulk Metal^® Z Foil (BMZF) Vishay’s
revolutionary for the resistive element. This technology
provides a significant reduction of the resistive components’
sensitivity to ambient temperature variations and applied
power changes. Designers now can guarantee a high degree
of stability an accuracy in fixed - resistor applications using
solutions based on BZMF technology.
The new technology provides inherently an extremely low
and predictable Temperature Coefficient of Resistance
(TCR), a remarkably improved load life stability, low noise
and availability of tight tolerance.
The TCR is a process capability not a selection process and
for most of the range is independent of ohmic value and lot
related variations.
A voltage divider can be fashioned by using two arbitrarily
selected VSMP1206s with a resultant tracking specification
of < 3ppm/°C. Extremely low tracking of < 1ppm/°C can be
supplied upon request.
The VSMP1206 has a conventional full wrap around robust
termination which insures safe handling during manufacturing
process, as well as providing stability during the multiple
thermal cyclings it will see over its service life.
The availability of tight absolute tolerance provides a good
cost solution for the variability of other components when
compiling the total error budget. BMZF offers the best
stability available; and is more than an order of magnitude
better than thin film technology. The noise generated by
the resistor is non measurable and its design and
construction make it well suited for high frequency
applications. The BMZF is the ultimate resistor component
for analog applications.
Most effective in applications where high stability is
required under load and extreme enviromental conditions.
