Charged EVs | Knowles introduces new line of safety-certified capacitors for EV onboard chargers

Knowles, a manufacturer of specialty electronic components, has released a new range of X1/Y2 safety-certified surface-mount multilayer ceramic capacitors (MLCCs).

These new safety-certified MLCCs have voltage ratings between 310 Vrms and 500 Vrms, making them an ideal solution for ensuring safe operation of the high-power AC/DC converters required for a variety of industrial and automotive applications.

Key features of the new range of MLCCs:

• High working voltage—Voltage rating and maximum capacitance value of 12 nF in 310 Vac class Y2
• High DC-rated voltage—1,500 V in compliance with EN60384-14 Annex H
• Tested for operation in harsh environments—rated to humidity grade IIIB (85° C, 85% RH, 1,000 hours)
• Wide operating temperature range: -55° C to 125° C
• Compact case—Creepage distance of up to 5 mm minimum packed into a 2720 case size, reducing required board space

These safety-certified MLCCs are available AEC-Q200 qualified and with a flexible termination option using FlexiCap, the company’s proprietary flexible epoxy polymer termination material.

“With our newly expanded portfolio of enhanced safety-certified MLCCs, electrical engineers designing the high-voltage power electronics required for applications ranging from electric vehicle onboard chargers to data center servers can reliably mitigate the effects of transient voltages and electromagnetic interference, ensuring safe operation,” said Nan Zhang, Director and Product Line Manager for Ceramic Capacitors at Knowles.
