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 0.005Ω.
The interdigitated terminations in the Type MV resistors provide a multiplepath distribution of the current into parallel resistance sections, which provides
low resistance values and non-inductive performance. This Exclusive NonInductive 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.
