Load
At room temperature, Surges are applied
10⁵ times every 2 seconds. Then after 1 or 2
hours, the sample is measured.
400V
0.47μF
At room temperature, the capacitor
"C" is charged with 70V, then discharged to
apply the voltage to the sample. Tested once
(resuming JASO A-1).

At a temperature of 85±3°C, the varistor voltage V1 is continuously
applied to the sample for 1000 to 1024 hours.
Then it is left at room temperature, for 4 to 24 hours before measuring.

cPulse-Voltage Breakdown Characteristic (VFS9V)
VFS9V EMIGUARDr use a self healing varistor- capacitor,
so that it can be used under a 500 to 600V surge that would
break conventional disc type EMI filters. As shown in the
50Ω
figure below EMIGUARDr withstands 2000V impulses
