type cdhc snap-in hybrid carboncap power ultracapacitors large cylindrical type the snap mount hybrid ultracapacitors are designed for board mountable power backup applications. the best applications for these type of ultracapacitors have low power, low energy, and low charge/discharge cycle rates. the main feature of these ultracapacitors is the ability to be rapidly charged preferably followed by a slow discharge. applications include solar lighting, led lighting, and portable devices. highlights - rapid charge - circuit board mountable - standard snap-in design specifcations operating temperature range storage temperature range C40 ?c to +60 ?c C40 ?c to +65 ?c rated voltage range 2.3 vdc, 2.50 vdc rated surge (do not discharge below 1 vdc) capacitance range 220 f to 1000 f capacitance tolerance C5% / +10% life at room temperature 10 years at rated voltage and 25 oc capacitance change 20% esr change 100% life test 1000 h @ rated voltage and +50 oc capacitance change 30% decrease esr change 100% increase cycle test >10,000 cycles (rated to half rated voltage at +25 c) capacitance change 20% decrease esr change 100% increase shelf life 1000 h without voltage at +60 c capacitance change 20% decrease esr change 100% increase rohs compliant ratings part number cdhc221k2r3sr cdhc301k2r3sr CDHC821K2R3SR cdhc102k2r3sr terminal confguration snap in snap in snap in snap in capacitance (f) (discharge w constant current at 25c) 220 300 820 1000 esr, dc (m), max 40 25 12 14 esr, ac @ 1khz (m), max 25 15 6 7 current - max peak (a) (1 s discharge rate to 50% of rated voltage) 26 41 87 77 leakage current (ma), max after 72 h at +25 c 0.20 0.55 0.50 0.70 usable power density, pd (kw/kg) (per iec 62391-2) 0.63 0.94 0.76 0.50 impedance match power, (kw/kg) 2.1 3.3 3.1 2.1 gravimetric energy density, emax (wh/kg) 5.2 6.6 7 5.2 energy available (wh) (at rated voltage) 0.13 0.18 0.49 0.60 weight (kg) 0.025 0.027 0.07 0.115 maximum continuous current (arms) (t=20c) 5 5.5 7.5 8 short circuit current (a) 92 153 383 329 cde cornell dubilier ? 1605 e. rodney french blvd. ? new bedford, ma 02744 ? phone: (508)996-8561 ? fax: (508)996-3830 obsolete
