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. F e at u r e s •Non-inductive design (less than 50 nanohenries) •Low voltage coefficient •Surface mount •Pd Ag terminations •J-bend terminals for applications involving shock and vibration A p p l i c at i o n s •Medical instrumentation •Power Supplies •Avionics •Light Magnification Systems S ER I E S S PEC I F I CAT I ON S Series MC101 MC102 MC103 MC104 MC202 MC204 Resistance Range (Ohms) 100Ω to 1,000M 200Ω to 5,000M 250Ω to 5,000M 1K to 5,000M 500Ω to 5,000M 1K to 5,000M Contact Ohmite for custom configurations.
