Offer

Holy Stone Enterprise specializes in high-specification multilayer ceramic capacitors (MLCCs) and specialized passive solutions:

  • Safety-Certified MLCCs (SCC Series): Class X1/Y2 and X2 safety capacitors certified to UL, EN, and IEC safety standards, suitable for primary-to-secondary coupling, surge isolation, and switching power supply EMI filtering.
  • High Voltage & Mid Voltage MLCCs (HVC / MVC Series): Rated voltages from 250 Vdc to 8,000 Vdc for snubber circuits, high-voltage inverters, and industrial power supplies.
  • Super Termination (Soft Termination) Capacitors: Flexible polymer conductive termination layers designed to absorb PCB bending and mechanical shear stress, preventing cracked bodies in high-vibration automotive power-trains and solar micro-inverters.
  • Automotive MLCCs: AEC-Q200 qualified components for battery management systems (BMS), electric vehicle chargers, and electronic control units.
  • High Capacitance & Low ESR Capacitors (HCC Series): Output smoothing MLCCs spanning up to multi-microfarad ratings for PoE (Power over Ethernet) circuits and DC/DC converters.
