The MICROTEST 6632C is purpose-built for evaluating capacitors with unmatched precision and speed. It supports ESR measurement from 10 Hz to 10 MHz, allowing engineers to assess performance under real-world operating frequencies. In Meter Mode, it provides instant ESR readings, while Sweep Mode offers impedance and phase vs. frequency plots to locate the Self-Resonant Frequency (SRF), revealing the capacitor’s high-frequency characteristics.

With a built-in ±12 V DC bias, the 6632C enables direct bias sweeps for C-V curve plotting, streamlining analysis for both development and production. The integrated dielectric constant (εr) measurement enhances material characterization, making it suitable for advanced research and quality control. Its switchable 25 Ω and 100 Ω output impedance supports a wide variety of test conditions, while the ultra-fast < 3 ms measurement speed boosts productivity in manufacturing environments.

Whether used in R&D labs or production lines, the 6632C delivers accurate, repeatable, and high-speed testing for capacitors, inductors, and other passive components.
