Their applications are extremely diverse, particularly in communication equipment, computers and peripherals, LCD TVs, portable DVD players, GPS navigation systems, in-vehicle TV/DVD/RADIO, high-definition television (including digital set-top boxes), LCDs, ultra-thin DVDs, set-top boxes, security equipment, firefighting devices, power banks, and more. Additionally, they are employed in financial and commercial ATMs, tax control machines, high-end computers, POS terminals, cash registers, mobile scanners, barcode readers, various automotive electrical devices, medical instruments, precision measuring instruments, control sections of industrial or household appliances, electronic toys, and electric vehicle control systems.
Surface-mounted aluminum electrolytic capacitors play crucial roles in electronic circuits, primarily including AC conduction, DC blocking, and providing electrical functions such as filtering, bypassing, coupling, decoupling, and phase shifting. They are indispensable components in electronic circuits. With the advancement of personal digital handheld devices, the usage of surface-mounted aluminum electrolytic capacitors continues to grow. As various electronic devices become smaller and more intelligent, many applications of traditional through-hole electrolytic capacitors will gradually be replaced by surface-mounted electrolytic capacitors.
From the perspective of product types and technical performance, surface-mount electrolytic capacitors will evolve toward higher rated voltages, larger or smaller rated currents, lower internal resistance, enhanced breaking capacity, restorable designs, as well as multi-line arrays, intelligent functionalities, and multifunctional integrated components or modules, to meet the design and production needs of more advanced end products.
Given the current state of China's manufacturing sector, the increasingly scarce labor resources have led to a sharp rise in labor costs. The high costs and low efficiency of manual component insertion severely constrain the automation and scaling of factories. Additionally, growing demands for higher performance and smaller sizes in electronic products are driving manufacturers to undergo transformations. The trend of replacing traditional through-hole capacitors with surface-mount aluminum electrolytic capacitors has thus emerged.
The market prospects for chip aluminum electrolytic capacitors are extremely broad, representing a large market aligned with future trends.
