Type MV Low Resistance Power Film Resistors

Values from 0.1 ohm to 50 ohms with Exclusive Non-Inductive Design

Type MV Low Resistance Power Film Resistors combine Caddock's

Exclusive Non-Inductive Design with many high performance capabilities of

Micronox ? resistance films to achieve these special advantages:

? Low Resistance - from 0.1 ohm to 50 ohms.

? Maximum Operating Temperature up to +275°C.

? Five Sizes and Power Ratings.

? Full Power Ratings without derating for Non-Inductive Performance.

? See MP900 Series Power Resistor Products for Resistances as Low as 0.005 Ω .

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.
