2199230-3 为 TE Connectivity(美国泰科)出品的 M.2 NGFF 插座,Keying Code B(B Key),母座类型,适用于标准 M.2 模块的电源/信号连接。该产品为卧贴(低姿态)安装,板上高度 4.2 mm(0.165 in),并配有安装支柱,金属触点镀金处理,工作温度范围 -40 – 80 °C。
2199230-3 采用符合 M.2 NGFF 尺寸与键位规范的插座结构,金属触点通常为铜合金基材并进行金镀,以保证可靠的电气接触和耐久性。塑料外壳材料选用耐高温工程塑料,适配常见回流焊工艺或其它组装流程。带柱设计便于在 PCB 上定位并通过螺柱或焊点实现可靠固定。
该插座适用于需要将 M.2 B-Key 模块(如部分 SATA/PCIe x2 SSD、WWAN/4G/5G 模块、扩展卡等)稳固连接到主板的场合。由于为低高度版本,特别适合空间受限的手持设备、超薄笔记本、工业控制器、套件式嵌入式系统及网络设备等对厚度有限制的应用。
工作温度范围 -40 – 80 °C 适应多数工业与消费类应用环境。金镀触点提高抗氧化能力与多次插拔寿命,但实际插拔次数与可靠性受应用环境(灰尘、湿度、振动)影响,应根据使用场景进行验证测试(如插拔寿命、接触电阻、机械振动与冲击测试等)。
在选用 2199230-3 前,请确认所用 M.2 模块的 Key(B)与 PIN 数配置匹配,尤其是电源与高速差分信号的引脚分配。若系统需更高工作温度范围、特殊防护或不同高度,应咨询 TE 官方文档以获取其他型号或定制选项。采购时关注包装、批次与生产日期以确保质量一致性。
如需更详细的机械尺寸图、PCB 布局建议、插拔寿命与电气参数,请参考 TE Connectivity 的官方产品资料或联系授权分销商获取技术支持与数据表。

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.
