anti-surge power type leaded resistor
resistors
EU
features
•
Excellent anti-surge characteristics
•
Stable characteristics of moisture resistance
up to high resistance range.
•
RCR50 +(1MΩ - 12MΩ), RCR50EN (1MΩ - 12MΩ) and
RCR60 (1MΩ - 12MΩ) are discharge resistors recognized
by UL1676 and c-UL(CSA-C22.2 No.1-M94).
•
RCR50EN (100kΩ - 33MΩ) and RCR60 (470kΩ - 56MΩ)
is approved by EN60065 14.1 safety. There is the case that
RCR50EN cannot meet CLASS II depending on a use.
•
Marking: Blue-gray body color with color-coded bands
•
Products with lead-free terminations meet EU RoHS
requirements. EU RoHS regulation is not intended for
Pb-glass contained in electrode, resistor element and glass.
•
Surface mount style “N” forming is suitable for automatic mounting

Notice of Surge Load
Surge withstanding load voltage for the resistors cannot be guaranteed when
the undermentioned 4 items get to a remarkable overload in comparison with
the conditions shown by surge withstanding voltage in Anti-surge
characteristics. Please contact KOA in advance if such a case is anticipated.
1. Peck voltage to be applied
2. Pulse width
3. Conditions of protecting insulation around the resistor

For resistors operated at an ambient temperature
of 70°C or above, a power rating shall be derated
in accordance with the above derating curve.
For example: In the figure, a metal wire is placed
less than 5mm away from the resistor body,
Discharge
there is such a case that causes an electric
discharge by a surge load 10kV and then
destroys the outer coating.
