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 pro-
vided in precision tolerances, high volt-
age ratings, and high resistance values.
The planar package design is low profile
for easy use with instrumentation, medi-
cal equipment, voltage regulators, and
power supplies.
