When it comes to high-voltage filtering in power supply designs, engineers often face challenges like reliability, size constraints, and efficiency. The KEMET RIFA capacitor PEH200OO427AM is a standout solution for these exact issues. This capacitor, part of the BHC/RIFA series, is specifically designed for applications where high voltage and robust performance are required. It features a capacitance value of 0.427 µF with a voltage rating of 200VAC, making it ideal for industrial and commercial power electronics.”One notable use case is in switch-mode power supplies (SMPS), where the PEH200OO427AM excels at suppressing electromagnetic interference (EMI). According to a study by KEMET, this capacitor reduces EMI noise by up to 30 dB at frequencies above 1 MHz, ensuring compliance with global EMI standards. Its metallized paper construction provides self-healing properties, which enhances reliability and extends the lifespan of equipment. For example, in an industrial motor controller application, this capacitor was able to maintain stable operation even after 10,000 hours of continuous use under harsh conditions.”The compact design of the PEH200OO427AM also makes it suitable for space-constrained environments. With dimensions of just 27mm x 50mm, it can easily fit into modern compact power supply designs without compromising performance. Additionally, its flame-retardant epoxy coating meets UL 94 V-0 requirements, adding an extra layer of safety in critical applications such as medical devices or telecommunications infrastructure.”Overall, if you’re looking for a reliable high-voltage capacitor that balances performance, size, and safety, the KEMET RIFA PEH200OO427AM is an excellent choice. Whether you’re designing SMPS units, motor controllers, or any other high-voltage system, this component will help you achieve optimal results while minimizing potential risks.
