In power supply applications, it generally includes power adapters, desktop power supplies, or server power supplies. The passive components required for power supplies must be able to maintain high product stability even when exposed to an environment with large temperature fluctuations, and have an ultra-low ESR (Equivalent Series Resistance) value and a high ripple current rating. The characteristics of high capacitance value and low ESR (Equivalent Series Resistance) of this series of products allow them to maintain low impedance at high frequencies, so as to support the noise suppression and ripple absorption functions in various applications. In this application, space is a key factor, and cost and higher efficiency are the priorities. The series of professional surface-mounted aluminum electrolytic capacitors for LEDs produced by Hongruikai Electronics can play a very good role.
