High-Value Chip Resistors Deliver Tight Tolerance

The 10-Gigaohm versions of these chip resistors can be trimmed to a tolerance of 0.1% while the 100-Gigaohm resistors can be trimmed to 0.25%. The chip resistors are also said to be very stable, in the range of 10 ppm/V with TCRs of 25 ppm/°C. They are available in sizes ranging from 0.02'' x 0.02'' (0202) up to 0.25'' x 0.125'' (2512), with custom sizes also available. Pricing for a 50-Gigaohm 2512 at 1% tolerance is $1.74 each/10,000.
