HP / Agilent 16089C Kelvin IC Clip Lead

The HP/Agilent 16089C Kelvin IC clip lead is a four-terminal test accessory engineered for precision impedance measurements of integrated circuits and irregular component geometries unsuitable for standard fixtures. Two insulated small-format Kelvin clips (1 mm width × 2 mm depth) minimize lead inductance and contact resistance, delivering accurate characterization across a 5 Hz to 100 kHz measurement window. The assembly includes approximately 1.3 m of cable terminated in a 4-terminal pair BNC connector and operates across 0°C to 55°C with humidity tolerance to 95% RH (non-condensing). DC bias capability ranges from −42 V to +42 V, with peak AC+DC voltage limited to ±42 V. Open and short compensations performed prior to measurement establish baseline accuracy; the DUT is then secured directly by the Kelvin clips. ESD precautions—including grounding straps and avoidance of direct contact with clip terminals—protect sensitive microcircuits during handling. This accessory integrates with Keysight LCR meters and impedance analyzers supporting four-terminal-pair connections, enabling deployment in research, quality assurance, and manufacturing metrology workflows.
