Packaging
HVC Resistors are supplied taped and reeled as per IEC 286-3.
High Voltage
Chip Resistors
HVC Series
HVC resistors are ideally suited for handling by automatic
methods due to their rectangular shape and the small
dimensional tolerances. Electrical connection to a ceramic
substrate or to a printed circuit board can be made by reflow
or wave soldering of wrap-around terminations.
Wrap-around terminations provide good leach properties and
ensure reliable contact. Due to the robust construction, the
HVC can be immersed in the solder bath for 30 seconds at
260°C. This enables the resistor to be mounted on one side
of a printed circuit board and wire-leaded components
applied on the other side.
HVC resistors themselves can operate at a maximum

temperature of 155°C (see performance above). For soldered
resistors, the joint temperature should not exceed 110°C. This
condition is met when the stated power levels at 70°C are used.
The PCB layout should avoid tracks running between the HVC
mounting pads, as this would compromise the LEV.
The LEV stated applies to operation at sea-level pressure, in a
non-condensing atmosphere and non-contaminating
environment. Voltage derating should be applied if low
pressure, high humidity or contamination may be encountered.
The termination clearance dimension (B) should be used in
conjunction with the creepage limit applicable to the circuit
application in order to determine the derated LEV.
