XH-HG Capacitor XH414HG/ Pb-free reflowable XH409HG (Under development) FEATURES * Pb-free reflowable: Superior heat resistance (260C peak) allows reflow soldering by Pb-free solder * Wide operating voltage range from 0V to 3.3V * High capacity: 0.08F with "414" size * Long Cycle Life: At least 10,000 times of charge/discharge * Simple charging circuit (constant voltage charging) * Wide operating temperature range: Operating temperature range: -20C to +60C The XH-HG is a capacitor with an excellent large current discharge characteristic at least 3 V, compared to its predecessor (XH414H). It is an environmentally friendly product that is reflow mounted by Pb-free soldering. It features high capacity, and long-term reliability, as well as a wide operating voltage range. It is thus suitable for backup power supply of clock and memory functions of mobile and information devices. APPLICATIONS Backup power supply for memory and clock functions of cellphone, PHS, cordless phone, digital still camera, PDA, MD player, game machine, and printer, etc. SPECIFICATIONS Electrical Specifications (Normal Temperature)*1 Type Size Weight (g) Maximum Use Voltage (V) Capacitance (F) Internal Impedance*2 () Diameter (mm) Height (mm) XH414HG 3.3 0.08 100 4.8 1.4 0.06 XH409HG (under development) 3.3 (0.05) (100) 4.8 0.9 0.05 *1.

Value measured using AC (Alternating Current) method at the fully charged state. <APPLICATION NOTES> * Prohibition ripple charging A ripple (high frequency fluctuation of voltage) in the charge voltage extremely lowers the capacitor performance. Be sure to charge capacitors with a stable voltage. * Charge voltage The age deterioration of the capacitor depends on the charge voltage. The age deterioration is accelerated as charge voltage goes higher. * Usage environment Aging degradation of the capacitor varies depending on the usage environment (temperature and humidity).
