Microtest 6621 Series LCR Meter

The Microtest 6621 Series LCR Meter combines a typical ±0.05% accuracy with a compact benchtop form factor, weighing just 3.4 kg with a 4.3-inch TFT display. Covering frequencies from 10 Hz to 30 MHz, the 6621 handles standard component testing through high-frequency characterization of RF inductors, MLCC capacitors, and EMI filter elements, delivering measurement performance comparable to full-size instruments at a fraction of the bench space.

Compact Form Factor, Full Performance

With sub-3 ms measurement speed, the 6621 Series supports high-throughput production testing alongside its R&D capabilities. Automatic level control maintains consistent test signal amplitude, open/short/load correction compensates for fixture parasitics, and BIN comparator functions enable automated pass/fail sorting on production lines.

Applications

The compact form factor makes the 6621 particularly well-suited for workbench-constrained environments, multi-station production floors, and portable field testing applications. Engineers characterizing RF inductors, MLCC capacitors, EMI filter components, and wound magnetics benefit from 30 MHz frequency coverage in a lightweight package that can move between test stations.
