High precision matched pair SIP resistor networks utilizing NiCr thin film spattered onto an alumina
substrates using high density patterning technologies. These models exhibit 1ppm 0.05%, tight ratio
tolerance and TC tracking (2T series). The 2S and 2M models are economical and show good performance.
A large variety of quick delivery resistances are available. The 2.5mm width and 5mm height is ideal for
high density layouts. Application for 2S(wide) include: Voltage dividers, feed back resistors, voltage
reference circuit in data processing, data transmission, precision power sources of industrial controls,
medical, measurements.
