New capacitors meet demanding 85/85 THB test

New Yorker Electronics has announced the release of the new MXT Metallised Polypropylene Film Capacitor Series from Cornell Dubilier. Created to suppress conducted EMI/RFI at a circuit’s power input, the MXT Series is ideal for use in harsh environments, having met the demanding 85/85 THB (Temperature, Humidity, Bias) test conditions. Class X2 capacitors like the MXT are generally connected across the AC input to prevent interference from spreading through power lines or other devices on the same circuit.

The series provides a wide selection of capacitance values, ranging from 0.1μF to 40μF, at 305VAC and 50/60Hz. It can operate within a temperature range of -40C to +110C. The durable box-style plastic case and epoxy seal are UL 94V-0 flame retardant. Also, the metallised polypropylene-film construction is self-healing, ensuring added reliability.

As the latest addition to the 85/85 THB-rated film capacitor lineup from New Yorker Electronics, the series has successfully passed accelerated testing at 85C heat with 85% relative humidity and an applied rated voltage for 1,000 hours. These extreme tests simulate the harsh operating conditions many commercial and industrial applications may encounter.

EMI/RFI suppression can be important in many commercial and industrial product applications. These include motors, AMR, Class 3 EV charging stations, solar micro-inverters, UPS, power supplies, industrial controls, and appliances. In these applications, the series serves two crucial functions: it filters out powerline noise to prevent it from affecting powered devices and prevents noise generated within a product from being carried to the power mains. Also, should the device fail, there is no shock hazard.

The series can also be used to connect a receiving circuit to an external antenna safely. In the event of a fault in an RF circuit, the MXT can block potential electrical shock hazards.
