Macrochip Series
High Voltage/High resistance
Precision thick Film surface Mount
With J-bend Option:
B
B'
Ohmite’s MacroChip resistors
bring precision high voltage
capabilities to surface mount
applications. Designed with
thick film on alumina substrate
technology, the resistors can
be provided in precision toler-
ances, high voltage ratings,
and high resistance values.
The planar package design
is low profile for easy use
with instrumentation, medical
equipment, voltage regulators,
and power supplies.

Note:
Silver solder is recom-
mended for Macrochip resistors.
Leaching of the silver in the ter-
mination will occur if non-silver
solder is used. 60/40 tin-lead sol-
ders are not recommended for
use with the Macrochip product.
