Wrap-around terminations
(3 faces)
Construction
Thick film resistor material, overglaze and organic protection are screen printed on a 96% alumina substrate. Wrap-around terminations
have an electroplated nickel barrier and solderable coating, this ensures excellent ‘leach’ resistance properties and solderability.
Marking
Components are not marked. Reels are marked with type, value, tolerance, date code and quantity.
Solvent Resistance
The body protection is resistant to all normal industrial cleaning solvents suitable for printed circuits.

Peak Voltage (V)
Resistors are tested in
accordance with IEC 60 115-1 using
both 1.2/50µs and 10/700µs pulse
shapes. 10 pulses are applied. The
limit of acceptance is a shift in
resistance of less than 1% from the
initial value.

The single impulse graph is the
result of 50 impulses of rectangular

intervals. The limit of acceptance
was a shift in resistance of less
than 1% from the initial value.

Peak Power (W)
The continuous load graph was
obtained by applying repetitive
rectangular pulses where the pulse
period was adjusted so that the
average power dissipated in the
resistor was equal to its rated power
at 70°C. Again the limit of acceptance
was a shift in resistance of less than
1% from the initial value.

of a printed circuit board and wire-leaded components
applied on the other side. DSC is compatible with typical
Pb-free soldering materials and temperature profiles.
DSC resistors are ideally suited for handling by automatic
40
methods due to their rectangular shape and the small
30
dimensional tolerances. Electrical connection to a ceramic
20
substrate or to a printed circuit board can be made by reflow
10
or wave soldering of wrap-around terminations.
DSC resistors themselves can operate at a maximum
temperature of 155°C. For soldered resistors, the joint

when the stated power levels at 70°C and recommended
ensure reliable contact. Due to the robust construction, the
pad and trace areas are used. Pad and trace area is defined as
DSC can be immersed in the solder bath for 30 seconds at
the total area of the solder pad plus all copper trace within two
260°C. This enables the resistor to be mounted on one side
squares of the edge of the solder pad. Allowance should be made
if smaller areas of copper are used.
