不良分析:1.通过以上调查,我司同批产品内部高温纹波验证2923H,D

Bad analysis: <br>1. Through the above investigation, the internal high temperature ripple of the same batch of products of our company is verified that 2923H, DF is currently below 4%, and the product appearance is normal. <br>2. Take the same batch of products to test that chloride ion and halogen are not contained. <br>3. The experimental life feedback of your company is not good. Our preliminary analysis is related to the difference in experimental conditions (such as <br>over-voltage, over-ripple current, over-temperature applied by instrument factors), <br>or whether the product has undergone similar experiments related to salt spray. Containing chloride ion or halogen will accelerate the <br>attenuation of the capacitor. The internal temperature of the capacitor will increase, the internal pressure will increase, and the explosion-proof valve of the product will be badly raised. <br>Please send the experimental samples back to our company, and then analyze the samples after receiving the samples. Our company will then carry out targeted bad reproduction verification.

Poor analysis:<br>1. Through the above investigation, I Division with the same batch of products internal high temperature ripple verification 2923H, DF is currently below 4%, and the appearance of the product is normal.<br>2. Take the same batch of products to test chlorine ions and halogens are not contained.<br>3. Your feedback of the experimental life is not good, our preliminary analysis and the condition of the experiment difference (e.g. instrument<br> factors apply over voltage, over-the-line current, overtemperature),<br> or whether the product is conducting a similar salt spray-related experiment that contains chlorine ions or halogens that will speed up the capacitance<br> Attenuation. Leads to an increase in the internal temperature of the capacitor, an increase in internal pressure, and a poor raise of the product explosion-proof valve.<br>Please send the experimental sampleback to our division, receive the sample and then for analysis of the sample.

Adverse analysis:<br>1.
