Smart Grid / Meters

Holy Stone Capacitors for Smart Grid / Meters

Holy Stone manufactures a broad line of multilayer ceramic capacitors (MLCC’s) used in digital smart meters and related power, monitoring, and communication equipment. The dominant market segment is single phase, single phase dual element, and three phase AMR and AMI meters. Available ceramic capacitor 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 6.3vdc 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:
