KTR18
Endured high voltage fixed thick film chip resistors
KTR18 (3216 size: 1 / 4W)
zFeatures
1) Power rating of 1 / 4W
2) Limiting element voltage of KTR series is twice compared with that of MCR series.
3) Highly reliable chip resistor Ruthenium oxide dielectric offers superior resistance to the elements.
4) ROHM resistors have approved ISO–9001 certification.
Design and specifications are subject to change without notice. Carefully check the specification sheet before using or
ordering it.

Rated voltage
The voltage rating is calculated by the following equation.
If the value obtained exceeds the limiting element voltage,
the voltage rating is equal to the maximum operating voltage.
E= P×R
Nominal resistance See Table 1.
