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.

DSC Series

Single Pulse

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.

Continuous Load Due

to Repetitive Pulses

Continuous Pulses

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.

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.

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. Pad and trace area is defined as

the total area of the solder pad plus all copper trace within two

squares of the edge of the solder pad. Allowance should be made

if smaller areas of copper are used.

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
