Capacitors, Inductors, Resistors

Measure, Analyze, and Optimize the Entire Application Process

For magnetics and passive component testing, Chroma manufactures a complete line of test equipment to measure the electrical behavior and characterization of capacitors, inductors, resistors, and wound components to the most current of specifications. Characterization tests include inductance, capacitance, resistance, impedance, dissipation factor, quality factor, leakage current, and insulation resistance. In addition, Chroma’s equipment can also test switches, connectors, lead wires, conductive, dielectric material, magnetic material, and semiconductor components.

The tests not only analyze the characteristics of components but also help to optimize the entire application process including automated manufacturing assessment, incoming and outgoing material inspection, quality verification, and R&D analysis in order to meet low cost, high efficiency requirements.

White Paper: LCR Measurement Primer

What is Impedance? What are the measurements of Impedance? This primer defines and explains the measurement of the impedance parameters known as L (inductance), C (capacitance), and R (resistance). Impedance parameters are characteristic of an AC circuit; this primer describes the impedance measurements that are typically used, including their equations. Also described are the connections to the device under test, and how to use test instruments to precisely measure impedance. In addition, primer describes the testing of individual passive components for inductance, capacitance, and resistance.
