Type MV Low Resistance Power Film Resistors combine Caddock's

Exclusive Non-Inductive Design with many high performance capabilities of

The interdigitated terminations in the Type MV resistors provide a multiple-

path distribution of the current into parallel resistance sections, which provides

low resistance values and non-inductive performance. This Exclusive Non-

Inductive Design provides significant performance improvements in high speed

or inductance sensitive electronic circuits, including high performance power

amplifiers, high-speed data transmission systems, high frequency video

amplifiers, current switching circuits, and current sensing circuits.
