Cornell Dubilier, a renowned supplier of electronic components, has expanded its product line with the introduction of the MXT Series capacitors. These new metalized polypropylene film capacitors are specifically engineered to suppress electromagnetic and radio frequency interference (EMI/RFI) in power circuits. This enhancement is significant for maintaining circuit integrity in environments with potential electrical disturbances.
A notable feature of the MXT Series is its durability, having successfully endured the rigorous 85/85 Temperature, Humidity, Bias (THB) test. This test involved exposing the capacitor to a demanding environment with 85°C heat and 85% relative humidity while under voltage for 1,000 hours. The successful completion of this test confirms the MXT Series capacitors’ reliability for use in harsh conditions.
EMI/RFI suppression is particularly crucial in electric vehicle (EV) charging stations, where it ensures that noise from powerlines does not disrupt the functioning of devices. Furthermore, it is key in preventing the propagation of internally generated noise to the power mains, maintaining the overall quality of power supply.
The MXT capacitors offer a range of capacitance values from 0.1 to 40 µF, operating at 305 V AC with a frequency of 50/60 Hz. These self-healing capacitors can withstand temperatures from -40°C to +110°C and come encased in a UL 94V-0 flame retardant plastic housing with an epoxy seal, enhancing their safety and durability.
Additionally, the MXT capacitors facilitate the safe coupling of receiving circuits to external antennas. They also serve as a protective measure, preventing electrical shock in the event of RF circuit failure.
Cornell Dubilier highlights that Class X2 capacitors, such as the MXT, are commonly employed across AC inputs to mitigate the spread of interference through power lines and maintain a clean power supply for other devices sharing the same circuit. These capacitors play a pivotal role in the stability and safety of electrical systems.
