Single-Tap .020 x .020 Series Thin Film Single-Tap Chip Resistors (.020 x .020 Series) Chip resistors provide variations in resistor material, temperature coefficient of resistance, substrate material, resistance and tolerance. Features Photo • • • Chip Size: .020” x .020” Silicon or Alumina Substrate Wire bond pads Available Options Include: • Resistor Tolerance to 0.5% • Nickel Chrome or Tantalum Nitride Resistor Materials • Back Gold Option API Technologies thin film single-tapped chip resistors .020 x .020 series are available in a wide range of resistances and tolerances with values available from 1 ohm to 600 kohms. The thin film resistor layer is made of Nickel-Chromium or Tantalum Nitride (TaN), with a gold or nickel-gold conductor layer. Applications for thin film center-tapped chip resistors include military and industrial hybrids, and medical, aerospace and communications equipment. Single-tapped chip resistors are available with either passivated nickel chrome or tantalum-nitride resistor metalization. • Nickel chrome provides excellent stability and temperature coefficient in hermetic applications • Tantalum-nitride provides superior moisture-resistance for non-hermetic applications.
