Performance Data
Construction
Resistive thick film material, overglaze and organic
protection are screen printed on a 96% alumina substrate.
The design and laser adjustment of the resistive element
optimises the limiting element voltage of the resistor.
Terminations
The chips are supplied with wrap-around terminations
suitable for soldering. Consult factory for alternative
termination options.
Solderability
The terminations have an electroplated nickel barrier and tin
finish. This ensures excellent ‘leach’ resistance properties and
solderability.
Marking
The body protection is resistant to all normal cleaning solvents
suitable for printed circuits. The chips are not marked and the
relevant information on type, value, tolerance date code and
quantity are recorded on the reel.

Application Notes
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.
