CONSTRUCTION
Solder Plating
Nickel Barrier
Dipped Conductor
The chips have a high alumina substrate (96% minimum)
with a ruthenium oxide resistance element and silver
palladium, nickel and solder plated terminations. A glazed
protection coat is applied to the resistive element (See
Fig. 1)

TERMINATIONS
Solderability The terminations meet the requirements
of IEC 115-1, Clause 4.17.3.2.
Strength
The terminations meet requirements of
IEC 68.2.21.
MARKING
96% min Alumina Substrate
Figure 1
All resistors are individually marked with 3 digits. The
first two digits are the significant figures and the third
defines the number of added zeros. Jumpers are marked
000. Type 0402 have no marking.
E96 1% components that can not be marked with 4 digits
will be marked with a standard 3 digit code. Details can
be supplied upon request.
SOLVENT RESISTANCE
The protective epoxy lacquer and marking are resistant to
all normal industrial cleaning fluids suitable for printed
circuits.
