MECHANICAL SPECIFICATIONS
Substrate
Alumina
Technology
Thin film
Film
Nickel chromium with mineral passivation
B type: SnPb over nickel barrier
Terminations
N type: SnAg over nickel barrier
G type: Gold over nickel barrier
SPECIAL FEATURES
Resistance values can be different on a given network
(R max./R min. as high as 300). Tooling charges might
be required depending on the ohmic values in the
same network. Please, consult VISHAY SFERNICE for
ohmic values, tolerances and also temperature coefficient
(e.g. ± 1 ppm/°C) outside the standard range.
PACKAGING
Several types of packaging are available: waffle-pack and
tape and reel.
