Designed with thick film on alumina substrate technology, the resistors can be pro- vided in precision tolerances, high volt- age ratings, and high resistance values. The planar package design is low profile for easy use with instrumentation, medi- cal equipment, voltage regulators, and power supplies. f ea ture S •Non-inductivedesign(less than 50 nanohenries) •Lowvoltagecoefficient •Surfacemount •PdAgterminations •J-bendterminalsforapplica- tions involving shock and vibration S er I e S S pec I f I cat I on S character IS t I c S Resistor Thick film on Alumina Resistance Range 100 Ohms to 5,000M 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 chart below Solder Silver solder is recommended for Macrochip resistors.
