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.

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 APPLICATIONS Medical instrumentation Power Supplies Avionics Light Magnification Systems SPECIFICATIONS Material Resistor: Thick film on Alumina Electrical Resistance range: 100 ohm to 5,000 Mohm Power rating: 0.75W to 3.25W Voltage rating: 2.0KV to 10.0KV Tolerance: 0.5% to 20% Operating Temperature: -55°C to +180°C TCR and VCR: see Slim Mox Note: 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 Macrochip product.
