New Yorker Electronics has announced the distribution of two types of rechargeable coin cell devices to cover the power needs of a wide range of devices and applications. The Cornell Dubilier double-layer supercapacitor generates higher power than batteries, delivers more energy than typical aluminum electrolytic capacitors and provides memory backup in circuits up to 6.3 W V DC. The Illinois Capacitors lithium ion coin cell batteries offer the highest mAh capacity available and with new encapsulation technology, significantly increase storage capacity.
The EDC and EDS series of coin cell style EDLC capacitors from New Yorker Electronics have quick response and recharge times. They offer higher power than batteries and greater energy than typical aluminum electrolytic capacitors without degradation over millions of charge-discharge cycles. These new supercapacitors can replace or extend battery life in on-board memory backup. They are electric double-layer supercapacitors that provide high capacitance values in a thru-hole stacked coin type package. Three case configurations are available for horizontal, vertical and radial-lead PCB mounting.
EDC and EDS series capacitors are ready to board mount in such applications as real-time clock (RTC) backup, power failure backup, battery assist and in market segments such as smart metering, HVAC controls, building automation, communication systems, appliances, instruments and other microprocessor-based devices. Because of their high volumetric power density, they can be an effective way to reduce board size and weight. Either series can be used as a drop-in replacement for similar value capacitors recently discontinued by other manufacturers.
Not only has the energy density per cell been improved in the Illinois Capacitor lithium ion batteries, the failure rate is superior to older designs. Encapsulation, unlike conventional stacking construction, has resolved older manufacturing issues, which can affect safety and reliability. As a result, RJD series batteries allow manufacturers to offer new levels of performance without product redesign.
With the increased performance levels, product run time can be increased by 20% or more versus a conventional lithium rechargeable coin cell battery. Alternatively, if product size is most critical, performance levels can be maintained with a physically smaller cell.
