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.

FEATURES

• Non-inductive design (less than

50 nanohenries)

• Low voltage coefficient

• Surface mount

• Pd Ag terminations

• J-bend terminals for applications

involving shock and vibration

Macrochip Series
