If the working voltage (U)is lower than the rated voltage (UR), the capacitor can be worked at a higher dV/dt.In this case, the maximum allowed dV/dt is obtained by multiplying the right value with UR/U. |

READ MOREAs electronic products become increasingly miniaturized and high-performance, high voltage metallized polypropylene film/foil capacitors are key components in the circuit, and their performance and stability are directly related to the operating efficiency and safety of the entire system. As a well-known capacitor manufacturer in the industry, Walson Electronics' CBB28 series high-voltage metallized polypropylene film/foil capacitor (sub-miniature) have won wide market recognition with their excellent design and manufacturing process. So, how does Walson Electronics ensure that this product can achieve high performance and high quality while maintaining an sub-miniature size?
From the product structure point of view, the CBB28 series capacitors use a winding structure of metallized polypropylene film and foil. This design not only makes the capacitor more compact, but also greatly improves its capacitance density. At the same time, the metallized polypropylene material itself has excellent electrical properties, such as low loss and low inherent temperature rise, which ensures that the capacitor can still operate stably under high frequency and high voltage environments.
In terms of performance parameters, the CBB28 series capacitors exhibit the characteristics of negative temperature coefficient of capacitance, which means that as the temperature rises, the capacity of the capacitor will decrease slightly, thereby reducing the risk of circuit instability caused by temperature changes to a certain extent. In addition, this series of capacitors also uses flame-retardant epoxy resin powder coating (compliant with UL94/V-0 standards), which further improves the safety performance of the product and effectively prevents fire accidents even under extreme conditions.
In order to ensure the high efficiency and high quality of the products, Walson Electronics always adheres to the advanced automation and industrialization cooperation concept in the production process. The company continues to introduce excellent production equipment from home and abroad, realizing full automation control from raw material processing to finished product manufacturing, greatly improving production efficiency and product consistency. At the same time, the company has also independently developed production management software, realized enterprise collaborative management, and ensured the smooth and orderly production process with scientific and efficient operation methods.
It is based on such production concepts and technical strengths that Walson Electronics' CBB28 series high-voltage metallized polypropylene film/foil capacitors (sub-miniature) have achieved an annual production capacity breakthrough of 1 billion units and maintained an orderly upward trend. This achievement not only demonstrates the company's deep foundation in capacitor manufacturing, but also provides customers with a stable and reliable product choice.
Walson Electronics ensures that the CBB28 series high-voltage metallized polypropylene film/foil capacitors (sub-miniature) can achieve high performance and high quality while maintaining an sub-miniature size through advanced production processes, strict quality control and continuous technological innovation. This not only meets the market's urgent demand for high-performance electronic components, but also makes a positive contribution to the development of the electronics industry.
