Resistors

High Voltage Resistance Chip Resistors

KTR18 (1206 size: 1 / 4W)

zFeatures

1) Power rating of 1 / 4W

2) Limiting element voltage of KTR series is 2.5 times 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.

zBefore using components in circuits where they will be exposed to transients such as pulse loads (short–duration, high–level loads), be certain to evaluate the

component in the mounted state. In addition, the reliability and performance of this component cannot be guaranteed if it is used with a steady state voltage that

is greater than its rated voltage.
