Series-connected supercapacitor modules maximise pulse power

November 04, 2016 // By Graham Prophet
AVX’ SCM Series supercapacitor modules offer high capacitance values, low ESR, low DCL, and long lifetime performance for hold-up, energy harvesting, and pulse power applications in the industrial and consumer electronics industries.

Comprising series-connected cylindrical, electrochemical, double-layer supercapacitors, the SCM Series supercapacitor modules are currently available in two voltage ratings (5V and 5.4V), and exhibit optimal pulse power handling characteristics, including: high capacitance values (0.47F – 7.5F ±20% tolerance), low ESR (4 mΩ – 300 mΩ at 1,000 kHz), low leakage (2 µA – 1 mA), 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, SCM Series 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 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.

SCM Series supercapacitor modules are rated for use in operating temperatures spanning -40°C to +65°C at 5.0 – 5.4V 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 so long as appropriate precautions are enacted, and is both lead-free compatible and RoHS compliance compatible.
