Vishay Foil Resistors

High Precision Bulk Metal^®Foil Molded Surface Mount Resistor

with TCR down to ꢀ ꢁꢁpm/C, Flexible Terpinations,

and Load Life Stability of ꢂ0ꢂꢂꢃ ꢄ (ꢃꢂ ꢁꢁp)

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)

Any value at any tolerance available within resistance range

 Electrostatic discharge (ESD) above 25 000 V

 Load life stability: 0.005 % (70 °C, 2000 h at rated power)

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.

 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

The flexible terpinations of this ꢁroduct also reduce

stress transference frop the PCB to the resistor0

 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

Voltage division with tight tracking < 3 ppm/°C can be

achieved with 2 randoply selected units even with a large

ratio between the two values.
