We conducted visual inspections and internal observations using X-ray CT on normal products and degraded products!
We would like to introduce the internal condition of aluminum electrolytic capacitors that have malfunctioned due to aging degradation, which was confirmed using X-ray CT. In degraded products, the internal pressure rises due to gas generated from the decomposition of the electrolyte, and as degradation progresses, there is a risk that the electrolyte may spout out due to the opening of the pressure relief valve. Additionally, it is believed that the gradual volatilization of the electrolyte occurs due to the deformation of the rubber cap, leading to eventual capacity loss and open failure. 【Overview】 ■Appearance Comparison - Conducted visual inspection of normal and degraded products. ■Internal Comparison using X-ray CT - Conducted internal observation of normal and degraded products using X-ray CT. *For more details, please refer to the PDF document or feel free to contact us.
