HVF Series Ohmite’s High Voltage Flip Chip Series incorporates high accuracy 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 temperature coefficients, less noise, tighter tolerances, better stability, higher resistance values, and higher voltage ratings. HVF is available in convenient 1206 and 2512 footprints.

Coating Silicone Solder Pad Material Silver (PdAg) Note: HVF Series should not be used with tin-lead based solder compositions. Only silver-based solder compositions are recommended. Care should be taken in the selection of the solder flux contained in the solder paste. Some pastes are "corrosive" and can damage the coating and also the resistive layer during the soldering process at high temperature. PCBs must be properly cleaned to remove any layers of moisture containing halides below the resistor. We recommend Halide Free (or Halogen Free) solder pastes, containing for example ROL0 or similar. It is advisable for the PCB layout to provide a slot, or air gap, underneath the downward facing resistor element, thereby increasing insulation resistance and reducing the possibility of capacitive coupling to the PCB. Under no circumstances should any copper trace be present in the layout directly under the resistive element.
