High Voltage Chip Resistors / Low Noise Chip Resistors
Series HVC
High Voltage Chip Resistors HVC Series combine proprietary Fine Line
Thick Film Technology and design to achieve a new level of high voltage
ratings and stability in SMD chip resistors. Nicrom’s technology features a
longer, high aspect ratio trace of lower resistivity film compared to
traditional thick film chip resistors.
Compared to standard chip resistors Nicrom’s HVC Series provides
unmatched performances and design efficiency resulting in lower voltage
coefficients and temperature coefficients, lower noise, tighter tolerances,
higher stability, higher resistance values and higher voltage ratings. Wire
bondable gold terminations and custom configurations available.
