FIGURE 4 - RECOMMENDED MOUNTING
Notes
(1) _{IR and vapor phase reflow are recommended.}
(2) _{Avoid the use of cleaning agents which could attack epoxy resins, which form part}
of the resistor construction
*
(3) _{Vacuum pick up is recommended for handling}
(4) _{If the use of a soldering iron becomes necessary, precautionary measures should}
be taken to avoid any possible damage / overheating of the resistor
* Recommendation: The solder fillet profile should be such as to avoid running over
the top metallization

CRYOGENIC TEST
Different expansion/contraction rates of composite materials
in resistors may induce discontinuities during temperature
excursions that are not evident at temperature extremes,
making an unreliable resistor appear normal. A good resistor
must also return to its initial value with no resistance drift. In
this demo, a VFR VSMP0805 precision resistor is monitored
through the range of +25°C, down to -196°C and back up to
+25°C. Results confirm the VSMP0805 exhibits only 5
ppm/°C TCR, experiences no discontinuities, and returns to
its exact same starting value, showing absolutely no change
in resistance (< 1 ppm measurement accuracy).
