Macrochip Series Datasheet

High Voltage/High Resistance Precision Thick Film Surface Mount

Res Macrochip product image

 

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.

Applications

  • Medical instrumentation
  • Power Supplies
  • Avionics
  • Light Magnification Systems

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
