Supercapacitors Have Optimal Pulse Power Handling Characteristics

AVX Corporation has released a new series of supercapacitor modules composed of series-connected cylindrical, electrochemical and double-layer supercapacitors. The SCM Series supercapacitor modules come in two voltage ratings (5 V and 5.4 V) and exhibit optimal pulse power handling characteristics, including: high capacitance values (0.47 F–7.5 F ±20% tolerance), low ESR (4 mΩ–300 mΩ at 1,000 KHz), low leakage (2 µA–1,000 µA), high energy density (1 to 5.6 Wh/kg), and long lifetime performance (50,000+ cycles).
The SCM Series modules can be used alone or in conjunction with primary or secondary batteries to provide extended back-up time, longer battery life and instantaneous pulse power in applications, including uninterrupted power supplies (UPS), wireless alarms, remote meters, global systems mobile (GSM) and galvanic skin response (GSR) transmissions, camera flash systems, scanners, toys and games.
The modules are rated for operating temperatures spanning –40° C to +65° C at 5.0–5.4 V balanced, or, with voltage de-rated to 3.9–4.6V 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 as long as appropriate precautions are enacted. The series is both lead-free compatible and RoHS compliance compatible.
All SCM Series parts are tested and qualified for life cycle, high temperature load-life, temperature and humidity characteristics, and vibration resistance, and they are shipped in bulk packaging. Current lead-time for the series is four to eight weeks, and custom modules are available upon request.
