(1) Rated Continuous Working Voltage (RCWV) shall be determined
from RCWV=
√Power Rating×Resistance Value or Limiting Element
Voltage listed above whichever less.
(2) Overload (Short-time Overload) Test Voltage (SOTV) shall be
determined from SOTV=2.5×Power Rating or max. Overload
Voltage listed above whichever less.
(3) Intermittent Overload Test Voltage (IOTV) shall be determined from
IOTV=4.0×Power Rating or max. Intermittent Overload Voltage
listed above whichever less.
(4) Resistance tolerance is of use besides range listed, please inquire.
(5) Resistance Range Type ERG : >10 Ω
Type ERX : <9.1 Ω
(6) As for the low resistance value range, "Z" is given to the part
number. (Refer to the explanation of part numbers.)
✽ Z type is non standard resistance values.
