zFeatures
1) Extremely small size and light weight facilitate the assembly of light, thinner, and smaller equipment.
2) Close match between wiper and resistive element reduces wiper noise.
3) Ruthenium oxide resistor material, with superb stability and resistance to humidity and the elements, offers the same
outstanding reliability of our existing product (MVR32).
4) Smoother and larger suction surface offers the same ease of mounting as that of the MVR32 chip.
5) Open design for reflow soldering.
6) Cross groove for easy adjustment.
7) Protective film prevents short circuits due to terminal contact.
8) The wiper is fully rotated during testing to guarantee its performance.
9) ROHM resistors have approved ISO9001- / ISO/TS 16494- certification.

Rated voltage
The voltage rating is calculated by the following equation. If the value
obtained exceeds the maximum operating voltage, the voltage rating
is equal to the maximum operating voltage.

•Before 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.
•The remainder of flux may negatively affect product performance and reliability. So please make sure to wash and remove flux completely washing.
