6 FAQs about [What are the inspection items for finished capacitors ]
How to test film capacitors?
There are two steps for testing film capacitors: manual and fully automatic sorting machine. Automatic sorting machine to test the electrical properties of film capacitors: Now, sampling film capacitors only needs to examine a few samples of the capacitors. A film capacitor automatic sorting machine is required to complete the examination.
What makes a reliable film capacitor manufacturer?
Reliable film capacitor manufacturers will pay attention to the quality of the finished products, and constantly carry out quality inspections and screenings in the process to ensure that consumers receive flawless products.
Are the dimensional drawings definitive for the finish of film capacitors?
The dimensional drawings in the individual data sheets are definitive for the dimensions. The finish of film capacitors is assessed in compliance with EPCOS finish specifications. For more detailed specification, refer to the "General technical information" chapter. When applicable, the individual data sheets are definitive for finishing.
What factors affect the failure rate of a film capacitor?
In the case of film capacitors, the two most relevant parameters affecting the failure rate are tem-perature and voltage. In the IEC61709:2011 standard, models for stress factors are consequently applied in order to convert the failure rates under reference conditions to values applying for oper-ating conditions.
What is a film capacitor automatic sorting machine?
A film capacitor automatic sorting machine is required to complete the examination. It can automatically check the open circuit, short circuit or defective products with large leakage current of the capacitor. The product is charged on the test conveyor chain test clamp for 60 seconds after charging. Perform leakage current performance test.
What is final inspection & approval for shipment?
Final inspection verifies the major properties of the end products batch by batch, usually by means of fully automated electrical selection tests. Approval for shipment helps certify that the shipped products comply with the specifications. It in-cludes: examination of papers accompanying the batch.
