The model is specialized in the insulation test of chip power inductor coil.
4 terminal testing circuits can be performed sufficiently with applied high voltage to ultra-low inductance coil. Maximum of 1000v (shown on screen) impression is possible to a minimum of 1μH coil.
Detailed response waveform is displayed as twice as many wave-form sampling resolution by testing machine.
High-speed test can be done with shortest test time of 30msec with 1 pulse application, and mass-production in line is possible. Each function of a test mode" and the "breakdown test mode" which performs detailed evaluation is carried in one set.
Impression of one pulse, high-speed test can be done without a judgment in shortest test time of 10msec, and mass-production line is possible.
It also suits to a choke , motor coil, and coil with few numbers of turns besides a chip power inductor.
