  • 接口规格:USB 2.0标准,Type-A母座,4Pin触点(覆盖电源与数据传输通道);
  • 端口配置:单端口设计,结构紧凑;
  • 封装形式:SMD(表面贴装)全贴工艺,适配自动化生产;
  • 安装角度:90度弯角布局,优化PCB空间利用;
  • 电气指标:额定电源电流1A(符合USB 2.0供电规范),额定电压5V,数据传输速率最高480Mbps;
  • 环境范围:工作温度-20℃~+85℃,满足多场景宽温需求。

二、结构设计与工艺特性

该连接器在结构上兼顾紧凑性与可靠性,关键工艺特点如下:

  1. 90度弯角全贴设计:90度弯角可节省PCB垂直方向空间,适合小型设备的高密度布线;全贴SMD封装无需插件孔,通过回流焊直接贴装,提升生产效率与一致性,降低手工焊接成本。
  2. 平口铜壳防护:采用高导电铜材质平口外壳,兼具两大功能——电磁屏蔽(EMI) 抑制外部干扰,保障数据传输稳定;机械防护 增强接口强度,防止插拔过程中变形。外壳表面常规做镀镍处理,提升耐腐蚀性。
  3. 触点工艺:4Pin触点采用镀金(或镀锡)工艺,确保低接触电阻(≤30mΩ),减少信号衰减,同时提升长期插拔可靠性。

三、电气性能与可靠性

U221-041N-4V33-F5的性能指标满足主流应用需求:

  • 电气稳定性:1A额定电流可支持USB设备常规供电,480Mbps传输速率覆盖U盘、键盘、鼠标等USB 2.0外设;接触电阻稳定,保障信号完整性。
  • 宽温适应性:-20℃~+85℃的工作范围,可覆盖消费电子(室内外)、车载电子(低温启动)、小型工业设备(高温环境)等场景。
  • 长寿命与抗干扰:触点插拔寿命≥5000次(符合USB连接器标准),满足日常频繁插拔;铜壳屏蔽有效抑制EMI干扰,避免信号串扰。

四、应用场景适配

基于小体积、宽温、自动化贴装等特性,该连接器适用于多类场景:

  1. 消费电子:移动电源、手机充电器、蓝牙音箱、无线耳机充电盒等小型便携设备,适配紧凑空间需求。
  2. 小型家电:加湿器、智能台灯、空气净化器等,宽温设计适应室内环境变化。
  3. 车载电子:车载充电器、行车记录仪、车载蓝牙等,90度弯角适配车载PCB狭小空间,宽温满足-20℃~+85℃的车载环境。
  4. 工业控制:小型传感器模块、数据采集终端、工业物联网设备,可靠性能适合工业场景稳定性要求。

五、品牌与封装优势

作为星坤的成熟产品,U221-041N-4V33-F5具备明显优势:

  • 品牌保障:星坤是国内专业连接器厂商,拥有完善的研发与生产体系,品控严格,交货周期稳定,可满足批量生产需求。
  • 封装适配性:SMD全贴封装兼容主流SMT生产线,无需额外工装;90度弯角优化PCB布局,减少布线复杂度,提升产品设计效率。

该连接器综合性能均衡,是小型化设备USB接口的可靠选择,可满足消费电子、车载、工业等多领域的应用需求。

Sourcing availability signal

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

Buyer sourcing scenarios

Examples of how common component sourcing requests are organized.

Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.

The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
