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 solder
coating, this ensures excellent ‘leach’ resistance properties
and solderability.
Note that anti-sulphur version parts below 100R are
produced in flip-chip format with the resistor element on
the underside.
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.

Lightning Surge
Lightning surge 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.

Single Impulse
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
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

Packaging
0603, 0805 and 1206 resistors are supplied on 8mm carrier tape and 2010 and 2512 resistors are supplied on 12mm carrier tape,
all on 7 inch reels as per IEC 286-3.
Application Note
PWC 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.
