Note

(1) As shown + 0.01

 to allow for measurement errors at low values

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).
