HP / Agilent 16197A Bottom Electrode SMD Test Fixture

The HP/Agilent 16197A is a bottom electrode SMD test fixture for precise impedance characterization of surface mount devices across a broad frequency spectrum. This fixture delivers reliable, repeatable electrical connections essential for accurate measurements in component testing and circuit validation. The 2-terminal design accommodates SMD packages from 0402 (1005 mm) through 1210 (3225 mm) form factors, with optional support for 0201 (0603 mm) devices. Maximum stress ratings of ±40 V peak (AC+DC) and 5 A enable testing across diverse component classes.
