EMI filters are available in 1206, 1809, and 1812 case sizes. The 2 kV rated capacitors are designed for AC terminations, as the EMI filters are capable of withstanding high-voltage surges. Primary reasons for use of the high-voltage chip capacitor include the EMI filters’ acceptance of ANSI/IEEE Std. 802.3 and ANSI/IEEE Std. 803af, making the high-voltage chip power-over-ethernet approved; 1500 Vrms at 50/60 Hz for 60 seconds; 2250 VDC for 60 seconds; and 2400 V peak voltage surge.
