Passive components manufacturer AVX Corporation has released a new series of supercapacitor modules for hold up, energy harvesting and pulse power applications. Composed of series-connected cylindrical, electrochemical, double-layer supercapacitors, the new SCM Series supercapacitor modules are currently available in two voltage ratings of 5 V and 5.4 V, and exhibit optimal pulse power handling characteristics. The peak current capability is 0.86 A to 173.5 A. In addition, the supercapacitors also offer high capacitance values (0.47 F–7.5 F ±20% tolerance), low equivalent series resistance (ESR) of 4 mΩ–300 mΩ at 1,000 KHz, low leakage current (2 µA–1,000 µA), high energy density (1 to 5.6 Wh/kg) and long lifetime performance (50,000+ cycles).
The supercapacitors are rated for use at operating temperatures ranging from –40° C to +65° C at 5.0–5.4V balanced, or with voltage de-rated 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 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. They are shipped in bulk packaging with a lead-time of four to eight weeks.
According to AVX, 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 such as 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.
