Cornell Dubilier Electronics, a US-based manufacturer of capacitors, has developed a new series of Y2 EMI/RFI suppression capacitors designed for harsh environments.

The MYH capacitor series is AEC-Q200 certified, meets a 2,000-hour Temperature, Humidity, Bias (THB) life test and is used in motors, automated meter readers (AMRs), uninterruptible power supplies (UPS), charging systems and appliances.

The line-to-ground capacitors filter out electromagnetic noise and have multiple international safety agency approvals. The 2,000-hour THB test conducted at 85° C and 85% relative humidity at rated voltage subjected the components to twice the industry standard test hours required to meet IEC 60834, Class III-B for THB, the company said.

Capacitance values range from 0.001 to 1 µF in 29 standard values, at 300 V AC, 50/60 Hz. Their operating temperature range is from -40° C to +110° C. The series has UL, CSA and VDE safety and performance certifications for Y2, line-to-ground applications.
