USB Type革新,探索新型接口的未來趨勢與挑戰(zhàn)-HIS時尚網(wǎng)

Okay, "USB Type" usually refers to the "physical connector shape and size" of a USB port or cable. There are several major types currently in use:
1. "USB Type-A:" "Description:" The most common rectangular connector, recognizable by its flat top edge. This is what you typically find on computers, laptops, tablets, and many peripherals. "Usage:" Primarily for host devices (like computers) connecting to peripheral devices (like keyboards, mice, printers, external drives). It's generally not reversible (you can only plug it in one way).
2. "USB Type-C (USB-C):" "Description:" A newer, smaller, and more versatile connector with a symmetrical,梯形 (ladder-shaped or trapezoidal) design. It's much smaller than Type-A and reversible (can be plugged in either way up). "Usage:" Found on modern smartphones, tablets, laptops, desktop computers, game consoles, and various peripherals. It supports higher power delivery and faster data transfer rates than older USB standards. It can also supply power to charge devices.
3. "USB Type-B:" "Description:" A square connector, often found on larger peripherals like printers, external hard drives, and some monitors (less common now). "Usage:" Typically used as a device connector, plugging into a host's Type

一、前言

那么一根Type-c線材能過2A電流肯定不夠用了，像VIVO、一加、華為等廠商已經(jīng)將數(shù)據(jù)線電流設計到5A。之前跟大家分享過2A電流下的內(nèi)阻和壓降測試，大部分線材的壓降都還能接受。那么，到了3A電流，內(nèi)阻大的線材壓降就不堪入目了，甚至可以講大部分線材根本過不了3A電流。小電流時代，內(nèi)阻大點影響倒不是很大；大電流時代，內(nèi)阻一定要??！這次給大家?guī)?A電流下的若干TYPE-C線材的內(nèi)阻和壓降測試，幫大家找出支持3A及以上電流的數(shù)據(jù)線，希望大家喜歡。
