The SMD 4 x 5.4mm electrolytic capacitor LCSC Electronics EasyEDA is a small but vital part of many modern electronic devices. Surface Mount Device (SMD) capacitors are preferred due to their compact design and high performance. These capacitors play a crucial role in power regulation, energy storage, and signal filtering in electronic circuits.
LCSC, a prominent electronic component distributor, offers a wide range of SMD electrolytic capacitors. These are widely used in both commercial and industrial electronic designs.
What is an SMD 4 x 5.4mm Electrolytic Capacitor LCSC Electronics EasyEDA?
An SMD (Surface Mount Device) electrolytic capacitor measuring 4mm in diameter and 5.4mm in height is designed to be mounted directly onto the surface of printed circuit boards (PCBs).
These capacitors offer several key characteristics that make them suitable for various electronic applications. Their voltage rating typically ranges from 6.3V to 50V, while the capacitance value generally falls between 1µF and 1000µF.
Being polarized components, they must be correctly oriented on the PCB to function properly. In terms of durability, they are built to last thousands of hours, depending on the voltage applied and the operating temperature.
Regarding material composition, these capacitors usually use an aluminum electrolyte, which is standard for its balance of cost and capacitance density. Some higher-performance variants may incorporate tantalum, although this is less common in this size range
