Holy Stone Enterprise Company Limited is based in Taipei, Taiwan, with factories in Lungtan, Taiwan. The company was founded in 1981 and is listed on the Taiwan Stock Exchange.
Holy Stone produces a broad line of standard and specialised products with the support of an advanced materials laboratory in Japan. Our modern factories utilise state-of-the-art equipment and technology. The facilities are ISO-14001, ISO-9001, QC 080000 and IATF 16949 certified. The company also holds many internationally recognised product approvals for its safety capacitors.
To complement the full range of ceramic capacitors, there is a strong focus on Application Specific Products and Technologies such as:
- TUV, U/L, CSA, and CQC recognized Safety Certified Capacitors (Class X2/Y3 and X1/Y2 surface mount) for LED driver, lighting, surge protection, EMI filtering, isolation, and all charger and adapter applications.
- 200Vdc – 8KVdc commercial High Voltage Ceramic Capacitors for a wide range of inverter, DC-DC converter, ballast, modem, and telecommunications applications.
- High CV (Capacitance/Voltage) Ceramic Capacitors for LED drivers, lighting, DC-DC and AC-DC converters, power supplies, industrial controllers, and telecommunications applications. Ideal for smoothing, decoupling and imput/ouput filtering.
- High CV Class 1 (NPO) products for xDSL, audio, matching and coupling circuits, cable modems, and general telecommunications applications. Also replacement of PPS film capacitors.
- Products optimized for specific applications such as back light inverter circuits and strobe/flash circuits for digital cameras, utilizing hybrid dielectrics such as X6S.
- Stacked Capacitors for power supplies, DC-DC converters, and industrial controller applications. Ideal for snubbers, input/output filtering, and smoothing where very high CV values and low ESR are required. Available in NPO and X7R T.C.’s up to 34uf, at 50Vdc to 1KVdc in 1 to 5 chip configurations.
