MRA-0510K00FE12

MRA www.vishay.com Vishay Mills Wirewound Resistors, Non-Magnetic, Non-Inductive, Axial Lead FEATURES • High temperature coating (> 350 °C) • Non-magnetic and all welded constructions greatly enhance frequency response. Combined with non-inductive Ayrton-Perry winding the inductive reactance and signal loss are almost totally eliminated. • Ideal for Audio Industry • Material categorization: For definitions of compliance please see www.vishay.com/doc?99912 STANDARD ELECTRICAL SPECIFICATIONS POWER RATING (1) POWER RATING (1) TOLERANCE (2) P25 °C W P25 °C W % CHARACTERISTIC U + 250 °C CHARACTERISTIC V + 350 °C RESISTANCE RANGE  WEIGHT (typical) g 1, 5, 10 0.01 to 15.0K 1.00 1, 5, 10 0.05 to 35.0K 3.87 MRA-12 MRA12 10.0 12.0 1, 5, 10 0.05 to 85.0K Notes (1) Vishay Mills MRA models have two power ratings depending on the operation temperature and stability requirements.
