Holy Stone Safety-Rated Ceramic Capacitors
Holy Stone has one of the broadest industry offerings of Safety Certified Multilayer Ceramic Capacitors (MLCCs). Our SCC series includes X2 and X1/Y2 classes rated at 250Vrm. These products are certified compliant with IEC60384-14 and UL60384-14. A 305Vrms 2220 size X2 version is also offered with compliance confirmed under TUV test report number 28208004 (May 27, 2010). These products are available in Class I NPO (COG) and Class II X7R dielectrics.
Characteristics of Safety MLCCs:
Safety Capacitors have designations of X or X/Y. The X designation is used in "line to line" circuit applications in which a failure would not result in electrical shock. The Y designation refers to "line to ground" circuit applications where failure and loss of the ground connection could result in electrical shock. The X/Y designation refers to products that have been certified for use in either "line to line" or "line to ground" applications.
The numeric designation following the X(2), X(1)Y(2) refers to the AC Voltage Rating and the Impulse Voltage to which the product has demonstrated compliance. In the case of X2, the Rated AC Voltage is 250Vrms with Impulse testing performed at 2500Vrms Impulse Voltage. In the case of the X1/Y2, the Rated AC Voltage is 250Vrms with Impulse testing performed at 5000Vrms. (see Summary Specifications Chart for all Characteristics)
Holy Stone also offers a line of X1Y2 Safety Certified Multilayer Ceramic Capacitors suitable for Automotive Applications. These products are particularly suited for charging systems for Electric and Chargeable Hybrid Automobiles. Please see our AEC Automotive product line for AEC-Q200 and ACC product line for TS16949 (PPAP Level 3 + AEC-Q200).
