Rubycon's YXJ series was developed as an improved version of the YXF series which was widely used in secondary filtering of power supply units. The YXJ achieves miniaturization, higher ripple current capability, and lower impedance compared with the conventional YXF series. Offering one rank smaller size while maintaining the same or better capacitance, impedance, ripple current, and life time specifications, the YXJ provides an advantage in helping in downsizing and performance improvement, as well as cost savings. With a wide range of capacitance values to offer, the YXJ series is suitable for use in a wide range of power filtering applications. They are best suited in applications for the Smart Meter, which forms the central function of a Smart Grid system and, requires the performance of miniaturization, long life, and high capacitance values.
