TE Connectivity 型号 1909763-1 为 UMCC(Micro-Coax Connectors)第一代板端插座,属 IPEX/UMCC 系列的 50Ω 推入式射频连接器。该件为单位端口(1 位)SMD(表面贴装)封装,适用于 PCB 板端与模块/线缆间的板对组件连接,频率覆盖至 6 GHz,旨在提供小体积、低剖面且性能稳定的射频连接解决方案。接口为内针(中心为母针/受体结构),接口直径约 2.0 mm,接口外露长度/高度约 1.25 mm,便于模块快速插拔与板上安装。
1909763-1 采用紧凑的推入式结构设计,接口为受体形态以配合对应凸针或插头使用。外壳与接触件材质通常采用镀镍或镀金的铜合金,以保证良好的导电性、低接触电阻和耐磨性,同时抵抗焊接与环境腐蚀。SMD 底座设计便于回流焊工艺,实现与常规 SMT 生产流程的兼容。结构上兼顾机械强度与最小占板面积,适合空间受限的无线终端与模块化设备。
该 UMCC 插座以 50Ω 特性阻抗设计,保证在宽频段内的阻抗匹配,降低反射损耗。对于 0–6 GHz 的应用,插座能提供稳定的插入损耗与回波损耗表现(具体 V.S.W.R. / S 参数视配对线缆/插头及 PCB 走线设计而定)。在高速无线(如 Wi-Fi、BT、GPS、LTE IoT 等)及射频测试接口场景中,能保证信号完整性与较低的串扰风险。由于采用 SMD 形式,布局时应考虑阻抗控制(微带或带状线过渡)与接地回流路径,以维持设计的射频性能。
在选型与采购 1909763-1 时,建议确认:
总结:TE 1909763-1 为一款面向小型化射频应用的 UMCC 50Ω 板端 SMD 插座,适合对空间、射频性能和自动化装配有要求的消费电子与模块化无线系统。在实际设计中建议配合厂方资料完成 PCB 和匹配件的校核,以获得最佳的射频与机械性能。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
