Thick Film Chip Resistors (Low Resistance Type)
Features
● Current sensing resistor
● Small size and lightweight
● Realize both low-resistance & High-precision by original thick film resistive element & special electrode
structure
● Suitable for both reflow and flow soldering
● Realize High-power by double-sided resistive elements structure that aimed to suppress temperature rising
● Low TCR
: ERJ2LW, 3LW, 6LW, 2BW, 3BW, 6BW, 8BW, 6CW, 8CW : ±75×10-6/K(ERJ6CW, ERJ8CW)
● Low resistance value : Thick film resistors available from 5 mΩ (ERJ3LW, 6LW)
● Reference standard : IEC 60115-8, JIS C 5201-8, JEITA RC-2144
● AEC-Q200 compliant
● RoHS compliant
■ As for packaging methods, land pattern, soldering conditions and safety precautions, please see data files.
