Overview
Smart meters have expected operational lifetime of 10 to 15 years once installed. As a
result, components with long life and virtually no-wear out mechanism in high humidity
environments are required.
After AC coupling, internal smart meter power rails can range from 1.8 V to 24 V. KEMET T521
High Voltage Polymer capacitors are well-suited for bulk decoupling on these high voltage DC
rails. With no electrolyte to wear-out, T521 devices will provide long operational life.
Hold-up energy reserves for RF modem (and power loss situations) can be provided by
either a KEMET Supercapacitor (EDLC) or T520 Polymer capacitor, depending on the height
available. These same high energy capacitors can also be used to provide peak current to
the RF modem during communication.
