Ohmite MC102821003JE Low voltage coefficient Datasheet

Macrochip Series
High Voltage/High Resistance
Precision Thick Film Surface Mount
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 tolerances, 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.

Solder Silver solder is recommended for
Macrochip resistors. Leaching of
the silver in the termination will
occur if non-silver solder is used.
60/40 tin-lead solders are not
recommended for use with the
