Current Sensing Chip Resistors

NCSR & NCST Series of Current Sensing Chip Resistors feature low resistance values, tight tolerance and stable characteristics in low profile flat chip construction. NCRS series uses temperature stable precision conductor construction, NCST uses low cost thick film construction. Precision resistance values from 0.5 milli-ohm (0.0005 ohm) to 1000 milli-ohm (1.0 ohm) are available in tolerances from +/-1% (F) ~ +/-5% (J). TCRs (resistance temperature coefficients) cover range from +/-50PPM/°C ~ +/-600PPM/°C. Industry standard case sizes from 0402 ~ 2512 with power ratings of 0.063W (1/16W) to 2.0W. Supplied RoHS compliant standard, with pure Tin terminal finish. Compatible with SAC soldering processes to +260°C. Supplied on tape and reel for high speed auto placement. Lead times from 5 ~ 8 weeks.  Samples are available.
