《GB/T 3615-2016电解电容器用铝箔》由TC243（全国有色金属标准化技术委员会）归口，TC243SC1（全国有色金属标准化技术委员会轻金属分会）执行，主管部门为中国有色金属工业协会。
Introduction
Background and significance of GB/T3615-2016 standard revision
GB/T3615-2016 "Aluminum foil for electrolytic capacitors" standard is a major upgrade on the original basis, mainly for medium and high voltage anode foil, low voltage anode foil and cathode foil technical requirements and testing methods have been fully optimized. The revision of this standard fully considers the industry development needs and technological progress, aiming to improve product quality and performance stability.
Comparison Analysis of Technical Specifications
| Product Category | Brand | State | Thickness Range(mm) | Cube Texture Content(%) |
|---|---|---|---|---|
| Medium and High Voltage Anode Foil | 1A97, 1A99 | Oa、H18 | 0.050~0.150 | >0.085~0.100: ≥90; >0.100~0.150: ≥95|
| Low Voltage Anode Foil | 1A85, 1A90, 1A93, 1A95, 1A97, 1A99 | Oa、H18 | 0.015~0.080 | -|
| Cathode foil | 1A90, 1070A, 3003 | Oa、H18、H22 | 0.015~0.080 | -
Interpretation of new technical requirements
Brand expansion: 1A97, a new brand for medium and high voltage anode foil, and 1A90, H18, H22 and other states for low voltage anode foil and cathode foil have been added respectively, enriching the product selection.
Joint requirements:It is clear that the number of joints per roll of cathode foil shall not exceed 1, and it shall be firm and flat, while no joints are allowed for anode foil. This helps to improve the consistency of product quality.
Actual application case
Case:When a certain electrolytic capacitor manufacturer selected medium and high voltage anode foil, it selected 1A97 grade H18 state with a thickness of 0.150mm. By comparing GB/T3615-2016 with the old standard, it was found that its cubic texture content increased to 95%, which significantly improved the durability of the capacitor.
Implementation suggestions
- Supplier selection:Give priority to enterprises with advanced production equipment and quality control systems to ensure that the materials meet the standard requirements.
- Detection focus:Focus on key indicators such as thickness deviation, cubic texture content and corrosion rate, and it is recommended to send them to third-party institutions for regular testing.
- State management: Select the appropriate foil state (such as Oa or H18) according to the specific application scenario to ensure the best performance.
