IWATSU SS-686/SS-687/SS-688/SS-689 world-first 100 MHz high-frequency Rogowski current probe

Brand: IWATSU

Origin: Japan

SS-680 series closed-loop Rogowski coil, max 100MHz measurement bandwidth, Ls SIC.GaN test, saturation
Overview

SS-680 series is a closed-loop Rogowski coil with measurement bandwidth up to 100 MHz, low-Ls measurement, suitable for SiC/GaN testing, and no magnetic saturation limitation.

    Key features of the SS-680 series:

  • Achieves a 100 MHz test bandwidth.

  • Suitable for measurement of high-speed power devices such as SiC and GaN.

  • Low-Ls measurement is achieved by miniaturizing and thinning the probe tip.

  • Can measure up to 12000 A.

  • Since magnetic saturation does not occur, large-current measurement can be performed with confidence.

  • The sensor section is shielded, providing good resistance to external noise and other external environmental factors.

  • Probe head operating temperature range: -10°C to +70°C

  • Maximum peak voltage: 1.2 kV
