Thick Film Surface Mount 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. • Non-inductive design (less than 50 nanohenries) • Low voltage coefficient • Surface mount • Pd Ag terminations • J-bend terminals for applications involving shock and vibration • Medical instrumentation • Power Supplies • Avionics • Light Magnification Systems Contact Ohmite for custom configurations. c h a r a c t e r 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 -55°C to +180°C Temperature TCR and VCR See chart below Solder 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. p e r f o r m a n c e d ata Characteristic Test Method Humidity MIL-STD-202, Method 103B, Condition B Dielectric Withstanding MIL-STD-202, Method 301, Voltage 750V Insulation Resistance MIL-STD-202, Method 302, Condition A or B Thermal Shock MIL-STD-202, Method 107G, Condition B, B-1, or F Load Life MIL-STD-202, Method 108A, Condition D Resistance to Solvents MIL-STD-202, Method 215G ±0.25% >10,000M or greater dry ±0.20% ±1.0% No degradation of coating or marking ±0.25% ±.020% Shock (Specified Pulse) MIL-STD-202, Method 213B, Condition I Vibration, High MIL-STD-202, Method 204D, Frequency Condition D Recommended Solder Profile High Voltage Macrochip Series 1-866-9-OHMITE • Int’l 1-847-258-0300 • Fax 1-847-574-7522 • www.ohmite.com • [email protected]
