Micsig RCP series Rogowski current probe measures AC currents up to 12000Apk, max. bandwidth up to 30MHz, withstand voltage is up to 1kVrms, nearly zero insertion impedance, greatly minimized the interference to the DUT.
A 1.6mm thin, flexible, clip-around Rogowski coil allow user easily pass through pin leg of TO-220 semiconductor devices. With 2% accuracy (typical) , accurately measures high-frequency and high-current signals like double-pulse dynamic test, monitor semiconductor switch current.

Measure the Id current of MOSFET

The RCP has excellent high-frequency measurement capabilities, easily handles high-speed signals and rapidly changing current waveforms, helping to observe high-frequency harmonic components when measuring the Id current of MOSFETs. (as shown the oscillation section).

Smallest coil cross-section

The cross-sectional diameter of the coil is only 1.6mm, allow engineers measure current in most difficult-to-reach parts of the circuit, such as narrow pin spacing chip like TO-220, TO-47.
Most compact flexible design easily solved the hard-to reach part issue, coil diameter support customzied made to meet more test requirements

BNC interface

Standard BNC interface to use on any oscilloscope.
