READ MOREIn the field of power electronics, WPR series high voltage filter/resonat capacitors are key components, and their performance stability and reliability are crucial to the operation of the overall system. Walson Electronics, as a leader in this field, has launched its WPR series of high voltage filter/resonant capacitors, which have won wide market recognition for their excellent insulation performance and self-healing capabilities. So how does Walson Electronics achieve these key features in the WPR series capacitors?
In terms of material selection, the WPR series capacitors use FR-4 epoxy tube shells, which have excellent insulation and heat resistance and can remain stable in high voltage and high temperature environments. At the same time, the dry structure design further improves the insulation reliability of the capacitor and reduces the performance degradation caused by environmental factors such as humidity.
In the core part of the capacitor, Walson Electronics selected metallized PP film as the dielectric. This film not only has excellent electrical properties, but also has good self-healing capabilities. When a capacitor has a slight breakdown or damage during use, the metallized PP film can quickly form a new conductive path to restore the normal working state of the capacitor, greatly reducing the risk of capacitor failure caused by local damage.
In addition to the advantages in materials, the WPR series capacitors have also made great efforts in production technology. Walson Electronics has its own factory, which realizes independent control and refined management from the procurement of raw materials to the production and processing of products, and then to quality inspection and sales. This not only ensures the consistency and stability of the products, but also greatly improves production efficiency and reduces production costs.
Walson Electronics also has its own international sales department, which is responsible for product promotion and sales in the global market. This means that customers can enjoy more convenient and efficient pre-sales consultation and after-sales service. Whether in product selection, technical support or logistics distribution, Walson Electronics can provide all-round and personalized solutions.
The reason why the WPR series high-voltage filter/resonance capacitors can stand out in the market is inseparable from the comprehensive advantages of Walson Electronics in material selection, production technology and sales services. These advantages jointly guarantee the excellent performance of the WPR series capacitors in insulation performance, self-healing ability, stability, safety and life. For customers who need high voltage filtering/resonance capacitors, the WPR series is undoubtedly a trustworthy choice.
