Smart Grid / Meters

Holy Stone manufactures a broad line of multilayer ceramic capacitors (MLCCs) 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:
