Ultra Precision Resistors

DIRECT Electronics offering Precision and Ultra Precision resistors has added tighter tolerance, improved temperature coefficients ratio tracking of ±5 PPM/°C and extended resistance range resistors in all lines for greater industry support.

Tolerance Precision up to 0.01% and temperature coefficients to 5ppm are now available in a variety of case sizes and on tape and reel for auto-handling. In addition to the standard E24, E96 & E192 resistance values, non-standards are possible. Full lines meet RoHS Directives, MIL-R-10509, MIL-R-55182, and other military grade.

Typical applications will include tester, measurement, sensor, transducer, and voltage cross-current regulation circuits and in many other applications that require precision feedback or dense packaging.
