Microtest 6632C Capacitor Analyzer

The Microtest 6632C Capacitor Analyzer is a purpose-built instrument for comprehensive capacitor characterization, delivering ±0.08% basic accuracy across 10 Hz to 10 MHz with specialized ESR (Equivalent Series Resistance) and SRF (Self-Resonant Frequency) measurement capabilities. Unlike general-purpose LCR meters, the 6632C is optimized for the specific parameters that define capacitor quality and suitability, ESR for power dissipation assessment, SRF for frequency-dependent behavior, and capacitance stability under DC bias conditions.

Built-in DC Bias for Capacitance Derating

The built-in ±12 V DC bias source enables capacitor characterization under real-world operating conditions, measuring capacitance derating curves for ceramic capacitors (especially Class II MLCC types that exhibit significant voltage-dependent capacitance changes). This eliminates the need for an external bias source and simplifies test setup for incoming inspection and production line testing.

Frequency Sweep Profiling

List sweep mode generates capacitance-vs-frequency and ESR-vs-frequency profiles in a single automated sequence. These profiles reveal the self-resonant frequency where the capacitor transitions from capacitive to inductive behavior, and the ESR variation that determines power dissipation at the operating frequency. For power electronics and RF applications, this data is essential for selecting the right capacitor for the circuit.

Applications

Capacitor manufacturers, electronic component distributors performing incoming inspection, power electronics designers, and RF engineers evaluating decoupling capacitors all benefit from the 6632C’s purpose-built measurement capabilities. The instrument is particularly valuable for MLCC characterization, electrolytic capacitor aging assessment, and film capacitor quality verification.
