Features
1) Superb solderability thanks to extra soldering electrode.
2) Close match between wiper and resistive element reduces wiper noise.
3) Mounting can be automated by using a carrier tape.
4) Extremely thin dimensions and light weight facilitate miniaturization of equipment.
5) Two-digit markings used to indicate resistance.
6) Special screwdriver (AD1804) available separately.
7) 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.

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.
