DC Bias Current Test System - Molded Power Inductor Test
MICROTEST DC Bias current test system is an integration test system of 6632 LCR Meter or impedance analyzer and 6243/6223 DC Bias Current Source.
MICROTEST 6243/6223 series bias current source output can be controlled by 6632 LCR Meter or impedance analyzer directly. MICROTEST maximum current can be as high as 320A. Frequency response up to 3MHz. The 6632 offers current graphical scan to inspect I sat and I rms. Analyze the curve of temperature change and saturation of inductor to see if it would burnout due to the temperature. List mode function, customers may select multiple parameters by 1 setting, all the test results are shown at the same time.
The age of 5G communication is coming; molding choke is wildly used in smart phone. Apple, Samsung, and Huawei……etc. use molding choke to fulfill high frequency high current. Therefore, the request of inductors from the engineers are high current efficiency and low internal resistance.
MICROTEST DC Bias current test system is the best system to analyze the magnetic saturation ( I sat) of the iron core when the inductor is at high current testing, and temperature rise ( I rms) cause inductance burned out.
