Y11212K00000B9L Overview

res 2K ohm 1/4W .1% 2512

SMR1D/SMR3D
Vishay Foil Resistors
High Precision Bulk Metal
®
Foil Molded Surface Mount Resistor
with TCR down to ± 2 ppm/°C, Flexible Terminations,
and Load Life Stability of ± 0.005 % (50 ppm)
FEATURES
Temperature coefficient of resistance (TCR):
± 2 ppm°C typical (- 55 °C to + 125 °C,
+ 25 °C ref.)
Tolerance: to ± 0.01 %
Flexible terminations ensure minimal stress
transference from the PCB due to a difference
in thermal coefficient of expansions (TCE)
Electrostatic discharge (ESD) above 25 000 V
Load life stability: ± 0.005 % (70 °C, 2000 h at rated power)
Resistance range: 5
to 80 k (for higher and lower
values, please contact us)
Power rating: to 600 mW at 70 °C
Non inductive, non capacitive design
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
tin/lead alloy
Matched sets with TCR tracking are available upon request
Any value available within resistance range (e.g. 1K234)
Prototype samples available from 48 h. For more
information, please contact
foil@vishaypg.com
For better performances please review SMRxDZ datasheet
Any value at any tolerance available within resistance range
INTRODUCTION
The SMRxD is a precision molded surface mountable
resistor offering all the elements of precision; including low
TCR, tight tolerance, long term stability, low noise, low
thermal EMF, and non-measurable voltage coefficient. It
utilizes the Bulk Metal
®
Foil technology for the resistive
element with its inherent low and predictable TCR and long
term stability. This surface mountable product affords similar
performance to the time tested S series molded through-hole
product.
The flexible terminations of this product also reduce
stress transference from the PCB to the resistor.
Voltage division with tight tracking < 3 ppm/°C can be
achieved with 2
randomly
selected units even with a large
ratio between the two values.
Our Application Engineering Department is available to
advise and make recommendations. For non-standard
technical requirements and special applications, please
