Panasonic Corporation announced today that it has commercialized its HL series electric double layer capacitor with the industry’s first 2000-hour operation life guarantee as a radial lead type. The new capacitor is suitable for the backup power supply circuit of industrial equipment requiring long operation life, such as storage equipment and smart meters, and automobile backup power supply circuits. Mass-production is scheduled to start in January 2017.
With the expansion of IoT and smart grid, demand for a backup power supply is on the rise for such things on the network as smart meters and storage equipment to allow them communicate or store data instantly when a power failure occurs. Industrial backup devices used in such equipment require long operation life without replacement and the capability of instantly supplying high-current output.
These devices also require strength to endure outdoor installation in severe environments as well as compact-sizing and lightweight design of the power supply circuit. Panasonic has developed unique electrolyte, which permits the new electric double layer capacitor to not only achieve the industry’s first 2000-hour-long guaranteed operation life as a radial lead type, but to supply large-capacity current in a low-temperature environment of -40°C.
Panasonic’s new electric double layer capacitor has the following features:
- Industry’s first 2000-hour-long guaranteed operation life without requiring replacement
• Life: 2000-hour guarantee. Panasonic’s conventional models offer a 1000-hour guarantee - Reduced internal resistance enables instant discharge of large current
• Internal resistance (1 kHz): 10~70 mΩ max.
[Panasonic’s conventional models: 100~300 mΩ max.] - Achievement of low-temperature guarantee down to -40°C, permitting outdoor installation in severe environments as well as automotive applications
• Temperature guarantee: -40~70°C (65°C)
[Panasonic’s conventional models: -25~70°C (60°C*3)]
