LED lighting: for voltage regulation and power factor correction
Our experienced quality inspectors and engineers provide our customers with unparalleled supply chain security, from supplier auditing and management to packaging and delivering products, following established processes and procedures to continuously optimize high-quality results.
We inspect, measure, verify and test electronic components starting from the outer packaging to confirm they meet the highest quality standards
Prepare test equipment and instruments in accordance with applicable standards and specifications. Confirm accuracy and qualification of test equipment
Appearance inspection: Check the integrity of the marks and labels; check the appearance of the capacitor to ensure there is no physical damage
Capacitor parameter test: measure the electrical parameters of the capacitor, including capacitance value, tolerance, withstand voltage, etc.
Electrical performance test:
Conduct a withstand voltage test to ensure that the capacitor will not breakdown under the specified voltage
Conduct insulation resistance testing to ensure good insulation performance
Conduct AC withstand testing to evaluate capacitor performance under AC power
Temperature characteristic test: Test the performance changes of capacitors under different temperature conditions, including changes in capacitance value
Mechanical performance testing: Check the mechanical strength and durability of the capacitor to ensure it can withstand mechanical vibration and shock
Reporting and Recording: All test results and observations, producing detailed test reports
