Center-Tap .030 x .030 Series Thin Film Center-Tap Chip Resistors (.030 x .030 Series) Chip resistors provide options in substrate, resistor material, temperature coefficient of resistance, resistance and tolerance. Features Photo Available Options Include: • Resistor ratio tolerances to 0.01% • TCR options available for 61AC series. Chip Size: .030” x .030” Silicon or alumina substrate Both sum and ratio of two resistors meet tolerance. Wire bond pads • • • • API Technologies thin film center-tapped chip resistors .030 x .030 series are available in a wide range of resistances and tolerances with values available from 2 ohms to 1 megohm. A center-tap is standard for values up to 500K, on a silicon or alumina substrate. The thin film resistor is made of Nickel-Chromium (NiCr) or Tantalum Nitride (TaN), with a gold conductor layer. Applications for thin film center-tapped chip resistors include military and industrial hybrids, and medical, aerospace and communications equipment. Center-tapped chip resistors are available with either passivated NiCr or TaN resistor metallization. • Nickel-chromium provides excellent stability and temperature coefficient in hermetic applications. • Tantalum-nitride provides superior moisture-resistance for non-hermetic applications.
