These solvent-resistant products come in a box-style plastic case and come with UL, VDE, ENEC and CQC approvals. Capactitors offer 100,000 hours of life cycle at 85 °C and are suitable for solar micro-inverters, UPS, power supplies, cash stations, vending machines and industrial control applications.

Original Press Release:

X2 Class Interference Suppressor Capacitors Meet 85/85 THB Tests AND Safety Agency Approvals

Illinois Capacitor’s new all-weather “MPX/MPXB” Series metalized polypropylene capacitors suppress conducted electromagnetic/radio frequency interference (EMI/RFI) before it can be transmitted via power lines to or from other devices. Designed to connect across the input of an AC mains powered device, the MPX meets the demanding 85/85 THB (Temperature, Humidity, Bias) test, as well as a full complement of safety agency X2 Class approvals, including UL, CSA, VDE and others. The MPXB is a specialized version, utilizing more robust construction, for use in AC divider circuits.

The 85/85 THB test is a form of accelerated testing that subjects a part to 85 C heat with 85% relative humidity and an applied bias voltage (240Vac) for 1,000 hours. This demanding test simulates the extraordinarily harsh operating conditions encountered by many commercial and industrial products.

AC line suppression applications are widespread, and include use with motors, AMR (Automated Meter Readers), solar micro-inverters, UPS, power supplies, cash stations, vending machines, industrial controls and appliances. The MPX also can be used as a safe means of coupling a receiving circuit to an external antenna. In the event of a failure, X2 Class devices do not present an electrical shock hazard to users of the equipment.

With self-healing, metallized polypropylene-film construction, MPX/MPXB interference suppressors provide excellent electrical and environmental performance. Capacitance ranges from 0.01 to 45 µF in 68 stock values, at 275/305 Vac, 50/60Hz. Overall operating temperature range is -40 °C to +110 °C. Life expectancy of 100,000 hours at 85 °C. Approvals include UL, VDE, ENEC and CQC. RoHS compliant. The solvent-resistant, box-style plastic case and epoxy-seal are both UL 94V-0 flame retardant. The MPX/MPXB is available now from major distributors.

The Illinois Capacitor MPX/MPXB series is a cost-effective way to improve EMI/RFI suppression needed to meet FCC or other regulatory approvals. For more information, contact, Illinois Capacitor, 2400 East Devon Avenue, Suite 292, Des Plaines, IL 60018 Phone: 847-675-1760. Email:
