Standard Rate of Capacitor (failure rate)
If two of three capacitances (R’-S’ phase, S’-T’ phase and T’-R’ phase) are under their failure rate, you
need to replace a new EMI filter right away. The table below lists the
standard rates (in blue color)
and
the
failure rates (in red color)
with unit uF.

Estimation by the failure rate: There are three capacitors in the EMI filter, when one of the
capacitor’s failure rate is over 15%, that means this capacitor is decaying. A decaying capacitor
might cause malfunction of the REG2000 and even cause safety hazards.
