Telecom

Holy Stone manufactures a broad line of multilayer ceramic capacitors (MLCC’s) used in the telecommunications industry. Applicable market segments include: mobile devices, IP telephony, LAN and WAN networking, cable modems, Ethernet devices, triple play, All-in-One printers, and set top boxes, receivers and Over-The Air equipment. Available Temperature Coefficients are ultra-stable Class I COG/NPO, and Class II X7R for greater capacitance/voltage density as well as X7T and X7P dielectrics for greater capacitance density and improved DC Bias characteristics. The Class I and Class II MLCC devices are available in sizes from 0603 up to 2225, at voltages from 100vdc to 5KVdc. Superterm® flexible termination is available upon request. This option incorporates a polymer layer in the termination structure which effectively absorbs external stresses and therefore reduces the incidence of potential product cracking. An open mode product design is also available as a customized option – this specialized internal electrode design reduced the possibility of a short circuit due to cracking under high mechanical or thermal stress conditions. A world leader in Safety-Rated capacitors, Holy Stone also offers X1/Y2 and X2 capacitors for safety circuits. Example applications include:

• Surge and line protection
• Isolation
• EMI
• Snubbers
• Smoothing
• Series and parallel busses
• Tip and Ring
• All power circuits
