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: MV 217 • • • • • 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. MV 228 MV 234 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 a mplifiers, high-speed data transmission systems, high frequency video amplifiers, current switching circuits, and current sensing circuits.
