Testing of ultra-low inductance coils, which was previously difficult, is now possible! Testing of a 1μH coil in as fast as 10 msec.
The "DWX-LI Series" is a product line specialized for high-speed testing of ultra-low inductance coils, focusing on insulation testing within chip power inductors. With a four-terminal testing circuit, it can apply up to 1000V to coils as small as 1μH. It displays detailed response waveforms with twice the waveform sampling resolution of conventional testing machines. Additionally, it features three modes optimized for insulation testing within coils, and it can accommodate coils with fewer turns. 【Features】 ■ Specialized for insulation testing within chip power inductors ■ Capable of applying up to 1000V to coils as small as 1μH ■ Displays detailed response waveforms with twice the waveform sampling resolution of conventional testing machines ■ Incorporates three modes: "High Speed / Test / Breakdown Test" in one unit ■ Fast operation with a minimum testing time of 10 msec, suitable for use on production lines *For more details, please refer to the PDF document or feel free to contact us.

Company information
Since our founding, we have focused on the development and manufacturing of various measuring instruments as a research and development-oriented company. Among these, the "Impulse Winding Tester" is used to inspect the damage of winding components in various motors and transformers used in LCD TVs, automobiles, and more. We have a strong track record of deliveries not only in Japan but also in China, South Korea, Taiwan, and other countries, receiving high praise. It allows for easy non-destructive testing of all good/bad judgments of winding components, including differences in winding count, material, and insulation defects. We develop and manufacture this testing machine domestically. Additionally, looking towards the next generation, we are conducting research themed on environmental purification, leveraging high-voltage impulse power supply technology in collaboration with universities.
