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 Pb-free 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.
General Note
Welwyn Components reserves the right to make changes in product specification without notice or liability.
All information is subject to Welwyn’s own data and is considered accurate at time of going to print.

The single impulse graph is the
result of 50 impulses of rectangular
shape applied at one-minute
intervals. The limit of acceptance
was a shift in resistance of less
than 1% from the initial value.

Application Notes
DSC 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
DSC 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. DSC is compatible with typical
Pb-free soldering materials and temperature profiles
DSC resistors themselves can operate at a maximum
temperature of 155°C. For soldered resistors, the joint
temperature should not exceed 110°C. This condition is met
when the stated power levels at 70°C and recommended
pad and trace areas are used. Allowance should be made
if smaller areas of copper are used.
