For virtually all detection needs Low Ohmic Chip Resistors

Features | Applications | Lineup

PMR Series

Features

  1. Ultra-low resistance (1mΩ and up)
  2. Original trimless design significantly improves current detection, making them ideal for large current fast switching circuits.
  3. The resistive element utilizes a special metallic alloy for low TCR characteristics.
  4. The unique chip structure minimizes thermal stress during temperature cycling, resulting in greater reliability.
  5. The world's first 0.25W (10mΩ) resistor in the 1608
    (0603inch) size
  6. A special metallic alloy is used for the resistive element, ensuring in superior resistance temperature characteristics: ±150ppm/ ºC

Features

0603 size ideal for compact devices of all types
