Maximum Pulse Rise Time (dV/dt):
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.

MKT21B capacitor uses metallized polyester film technology, which enables the capacitor to maintain low loss and good stability at high frequency operation. Its internal laminated structure not only improves the overall performance of the capacitor, but also effectively improves its withstand voltage and service life. The product's housing is made of high-quality plastic (compliant with UL94 V-0 standard), which has good fire resistance and protection performance, and is suitable for more complex working environments.

MKT21B capacitors also have high dv/dt capability, which means that they can also work stably in high voltage and rapidly changing current environments. This feature is particularly critical for applications that require fast response and high stability, and can effectively improve the reliability of the equipment.

Epoxy resin sealing is another outstanding feature of MKT21B capacitors. The sealing design not only prevents the intrusion of external moisture or dust, but also effectively resists the corrosion of chemicals in the environment to the inside of the capacitor, further extending the service life and ensuring the stability of the product in harsh environments.

Walson Electronics' advantages and production capabilities
Walson Electronics has its own factory, which can realize self-control of all production links from raw material procurement, design to final product, ensuring the high quality and consistency of the product. The company's self-developed production line uses advanced technology and equipment, so that each MKT21B capacitor can be strictly controlled during the manufacturing process and meet international standards.

Walson Electronics also has its own international sales department to ensure that it can respond quickly to customer needs. Whether in terms of product customization services or delivery time, Walson can provide flexible and efficient solutions. With these two advantages, Walson Electronics not only occupies a place in the domestic market, but also gradually expands its influence in the international market.

Application fields of MKT21B capacitors
MKT21B box-type metallized polyester film capacitors are widely used in many fields due to their high voltage resistance, high stability and strong protection. For example, in communication equipment, MKT21B capacitors can be used for filtering, decoupling and signal stabilization to ensure the stability of equipment in high-frequency environments. In the field of automotive electronics, with the popularization of electric vehicles and intelligent vehicles, the requirements of electronic systems for capacitors are becoming more and more stringent. MKT21B capacitors can withstand higher voltage fluctuations with their high dv/dt capabilities and are widely used in automotive electronic control systems.

MKT21B capacitors are also suitable for industrial control, LED lighting, power modules and other occasions. Its high reliability and environmental resistance enable it to provide long-term stable working performance in these fields.

MKT21B box-type metallized polyester film capacitors (laminated version) have become an ideal choice for many demanding electronic products due to their advanced technology, excellent performance and wide range of applications. As its manufacturer, Walson Electronics, with its own factories and international sales network, is able to provide high-quality products and thoughtful customer service to meet the various needs of global customers for capacitors.
