FIGURE 3 - 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) _{In case of using soldering iron, measurement precautions should be taken to avoid}
damaging the resistor
PULSE TEST
TEST DESCRIPTION
All parts baked at +125°C for 1 hour and allowed to cool at room
temperature for 1 hour, prior to testing. By using an electrolytic
0.01µF capacitor charged to 1200 VDC, a single pulse was
performed on 30 units of 1206, 10K of Surface Mount Vishay Foil
resistor and Thin Film resistor. The unit was allowed time to cool
down, after which the resistance measurement was taken and
displayed in ppm deviation from the initial reading.
