Series-connected supercapacitors
9 November 2016
Passive Components
AVX has released a new series of supercapacitor modules comprised of series-connected cylindrical, electrochemical, double-layer supercapacitors. The SCM Series is currently available in two voltage ratings (5 V and 5,4 V), and exhibits optimal pulse power handling characteristics, including: high capacitance values (0,47 F – 7,5 F ±20% tolerance), low ESR (4 mΩ – 300 mΩ at 1000 kHz), low leakage (2 μA - 1000 μA), high energy density (1 to 5,6 Wh/kg), and long lifetime performance (50 000+ cycles).
Designed to provide reliable hold-up, energy harvesting and pulse power solutions, the modules can be used alone or in conjunction with primary or secondary batteries to provide extended backup time, longer battery life, and instantaneous pulse power in applications such as uninterrupted power supplies (UPS), wireless alarms, remote meters, GSM and galvanic skin response (GSR) transmissions, camera flash systems, scanners, toys and games.
The supercapacitor modules are rated for use in operating temperatures spanning -40°C to +65°C at 5,0 – 5,4 V balanced, or, with voltage derated to 3,9 – 4,6 V per cell, -40°C to +85°C balanced. Unbalanced options are also available. Packaged in plastic or shrink-wrapped cases spanning 14 mm to 24 mm in length with vertical or horizontal radial leads, the series is compatible with hand, reflow and wave soldering, and is both lead-free compatible and RoHS compliant.
