Ohmite’s MacroChip resistors
bring precision high voltage
capabilities to the surface
mount level. 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
• Low voltage coefficient
• Surface mount
• Pd Ag terminations
• J-bend terminals for applications
involving shock and vibration
