More InfoQuote

The Chroma 19301A Impulse Winding Tester applied with high/ low inductance test technology has 1000Vdc impulse voltage and 200MHz high speed sampling rate that can satisfy most of the power inductors test requirements for wide range of inductance products from 0.1uH to 100uH. The built-in Area Size Comparison, Differential Area Comparison, FLUTTER value and LAPLACIAN value functions are able to inspect the coils for poor insulation effectively.

The inspection of winding components includes electrical characteristics and safety withstand voltage tests. Commonly poor insulation of coils is the root for causing layer short and output pin short-circuited during usage. The reason could result from bad initial design, poor moulding processes or deterioration of insulating materials; therefore, adding the coil layer short test to winding components has its necessity.

The Chroma 19301A is an equipment specifically designed for testing winding components utilizing a high voltage charged micro capacitor (low test energy) and coil under test to form an RLC parallel resonant. Analyzing the oscillation decayed waveform via a high speed and sophisticated sampling process technique can successfully detect the coils with poor insulation, also provides withstand voltage tests on winding quality and cores for power inductor components.
