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.
