X8821WVS-03-9TSN 2.5mm线对板连接器针座产品概述

X8821WVS-03-9TSN是中国星坤(XKB Connectivity)推出的2.5mm间距线对板连接器针座,兼容JST XH系列标准,采用立贴式(SMD)封装,专为紧凑空间内的小功率电气连接设计,核心满足3Pin线对板的可靠信号/电源传输需求。

一、产品核心定位与基础特征

该针座针对小型化、高集成度设备的内部连接场景,核心特征可概括为:

  • 间距标准:遵循2.5mm行业通用间距,适配主流XH系列端子;
  • 封装形式:立贴式SMD,无需PCB插件孔,节省板上空间;
  • 结构简化:无扣设计,降低插拔阻力的同时适配常规端子配合;
  • 材料升级:采用PA9T耐高温塑料,替代传统PA66,提升环境适应性。

二、关键技术参数深度解析

1. 结构与尺寸参数

  • 插针配置:1排×3Pin(单排3针),满足基础3线连接需求;
  • 板上定位:X轴底边长度(间距线)12.5mm,明确PCB布局时的占位范围,方便设计人员精准开孔与布局;
  • 封装类型:SMD表面贴装,引脚采用贴片式设计,适配自动化回流焊工艺。

2. 电气性能参数

  • 额定电流:3A/Pin,可满足小型家电、办公设备的常规电源传输(如5V/12V低功率电路);
  • 额定电压:250V AC/DC,覆盖低压电气系统的安全电压范围;
  • 工作温度:-25℃~+85℃,满足绝大多数室内/工业环境的温度要求(如智能家居、小型工业控制器)。

3. 材料与可靠性参数

  • 触头系统:黄铜基底+锡镀层——黄铜导电率高(约28%IACS),锡镀层抗氧化、易焊接,接触电阻稳定(通常≤20mΩ);
  • 绝缘塑料:PA9T(聚邻苯二甲酰胺)——相比传统PA66,耐温性提升(长期使用温度可达120℃),阻燃等级UL94V-0,符合安全规范;
  • 封装工艺:SMD引脚采用镀锡处理,确保回流焊时的焊接可靠性,无虚焊风险。

三、材料与工艺的差异化优势

1. 触头系统:平衡导电与可靠性

黄铜基底保证低接触电阻,锡镀层避免触头氧化(尤其是在潮湿环境下),同时提升焊接兼容性——无论是手工焊还是回流焊,均能实现牢固连接,减少后期接触不良问题。

2. 绝缘塑料:PA9T的环境适应性

PA9T塑料具有低吸湿性(吸水率仅0.15%),避免因潮湿导致的绝缘电阻下降;同时耐化学性强,可抵抗常见溶剂(如酒精、清洁剂),适合工业设备的清洁维护场景。

3. 立贴封装:适配自动化生产

SMD封装无需PCB钻孔,可直接贴装在PCB表面,提升生产效率(适配SMT流水线);同时节省板下空间,便于设备内部紧凑布局(如小型打印机、智能手环的内部连接)。

四、典型应用场景

该针座因小间距、高可靠、立贴省空间的特点,广泛适配以下场景:

  • 小型家电:咖啡机、加湿器、空气净化器的内部电源/信号连接;
  • 办公设备:打印机、扫描仪、投影仪的内部模块连接;
  • 工业控制:小型PLC、传感器模块、物联网网关的线对板连接;
  • 消费电子:智能家居设备(如智能灯泡、传感器)、可穿戴设备的内部布线。

五、安装与可靠性验证

1. 安装注意事项

  • 采用回流焊工艺时,需控制温度曲线(峰值温度≤260℃,时间≤10s),避免PA9T塑料变形;
  • 贴装时需对齐PCB焊盘,确保引脚与焊盘完全贴合,减少虚焊概率。

2. 可靠性验证

  • 插拔寿命:常规端子配合下,插拔次数可达100次以上(符合行业标准);
  • 绝缘电阻:常温下≥1000MΩ,高温85℃时仍≥100MΩ;
  • 阻燃性能:UL94V-0等级,可通过垂直燃烧测试,提升设备安全等级。

总结:X8821WVS-03-9TSN是一款高性价比的XH系列兼容针座,兼顾小间距设计与可靠性能,适合对空间、成本敏感的小型设备内部连接,是替代进口XH系列针座的优质选择。

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
