Chip trimmer potentiometers
MVR32
!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.
