Ohmite’s High Voltage Flip Chip Series incorporates high accu-
racy screen printing technology to achieve high voltage capability
in a stable flip chip SMD chip resistor package. The HVF Series
offers unmatched performance in comparison to standard chip
resistors. Its unique design provides lower voltage and tempera-
ture coefficients, less noise, tighter tolerances, better stability,
higher resistance values, and higher voltage ratings. HVF is
available in convenient 1206 and 2512 footprints.
