MVR21

Features

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 (MVR22).

4) Open design for reflow soldering.

5) Cross groove for easy adjustment.

6) Protective film prevents short circuits due to terminal contact.

7) ROHM resistors have approved ISO-9001 / ISO/TS 16949 certification. Design and specifications are subject to

change without notice. Carefully check the specification sheet supplied with the product before using or ordering it.

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.

E : Rated voltage (V)

P : Rated power (W)

R : Nominal resistance (

Ω)

E = P

× R

Power must be derated according to the power derating curve in
