High Purity Alumina Substrate
Ni alloy thin-film resistive element
Wrap around electrodes
RoHS compliant (100% matte tin over
Nickel).
Various Sizes
2 to 8 resistors/package
Resistance tolerances to 0.02%
Tracking tolerances to 0.02%
TCR as low as ±5 ppm/°C
TCR tracking of ±1, ±2 or ±5ppm/°C
Description:
These surface mount resistor networks feature wrap around electrodes in various product sizes. The number of
resistors in the package is either 2, 4 or 8. Because all of the resistors are fabricated together, these networks offer
extremely tight tracking and TCR tracking tolerances which are difficult to achieve by using individual, discrete resistors.

The first 3 digits are significant figures.
The last digit specifies the number of
zeros. For values <100Ω, “R” is used
to designate the decimal position.
Multiple values are separated by a
slash ( / ).
e.g. 1001 = 1,000Ω
75R0 = 75.0Ω
