HVF Series
High Voltage
Flip Chip Film
F e at u r e S
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 resis-
tors. Its unique design provides lower voltage and
temperature coefficients, less noise, tighter toler-
ances, better stability, higher resistance values, and
higher voltage ratings. HVF is available in convenient
1206 and 2512 footprints.
• High voltage up to 3,000 volts
• Industry standard sizes
• Working temperature range –55°C to 200°C
• Designed for automatic insertion
• Non-magnetic construction

Note:
HVF Series should not be used with tin-lead based solder compositions. Only silver-based solder composi-
tions 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 pro-
cess 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.
