Cornell Dubilier, a division of Knowles Corporation, has introduced the new MXT Series Metallized Polypropylene Film Capacitor.

Class X2 capacitors, like the MXT, are typically connected across the AC input to prevent interference from spreading through power lines or other devices on the same circuit.
The MXT Series is designed to suppress electromagnetic/radio frequency interference (EMI/RFI) at a circuit’s power input. It’s built to withstand harsh environments and has passed the demanding 85/85 THB (Temperature, Humidity, Bias) test requirements.
The MXT offers a wide selection of capacitance values, ranging from 0.1 to 40 μF, at 305 Vac and 50/60Hz, and can operate within a temperature range of -40° to +110° C. The durable box-style plastic case and epoxy seal are both UL 94V-0 flame retardant. Additionally, the metalized polypropylene-film construction is self-healing, adding reliability.
As the latest addition to Cornell Dubilier’s 85/85 THB-rated film capacitor lineup, the MXT has successfully passed accelerated testing at 85° C heat with 85% relative humidity and an applied rated voltage for 1,000 hours. These extreme tests effectively simulate the harsh operating conditions that many commercial and industrial applications may encounter.
EMI/RFI suppression can play an important role in many different commercial and industrial product applications. These include motors, Class 3 EV charging stations, industrial controls, and more. In these applications, the MXT filters out powerline noise to prevent it from affecting powered devices, and it prevents noise generated within a product from being carried to the power mains. Additionally, should the device fail, there’s no shock hazard.
The MXT can also be used as a safe means of coupling a receiving circuit to an external antenna. In the event of a fault in an RF circuit, the MXT can block potential electrical shock hazards.
