X8821WRS-02L-LPSN是中国星坤(XKB Connectivity) 推出的一款小型化线对板针座,核心作用是实现导线与PCB板的可靠电连接,适配小功率电路的信号传输与电力供应需求。其定位为高性价比、高可靠性的基础连接器件,广泛应用于消费电子、工业控制、智能家居等对空间紧凑、振动抗性有要求的场景。
该产品的核心参数围绕“小型化、标准化”设计,关键指标如下:
相比传统直插针座,卧贴SMD封装无需在PCB上钻孔,可节省约30%的布局空间,适配智能穿戴、小型家电等“轻薄化”设备;同时支持回流焊工艺,自动化贴装效率比手工焊接提升5倍以上,降低人工成本与焊接一致性问题。
针对工业手持设备、车载小模块等易受振动的场景,带扣设计可实现“插拔锁定感”——线端连接器插入时自动卡合,避免运输或使用中因振动脱落,经测试可满足IPC-610振动标准(10Hz~2000Hz,加速度1.5g)。
LCP(液晶聚合物)外壳具备优异的耐温性(长期使用温度-40℃~130℃)、耐化学性(抗清洁剂、溶剂腐蚀),适合厨房家电(如高温加湿器)、户外传感器(如温湿度监测)等复杂环境。
黄铜触头导电率达1.07×10^7 S/m,锡镀层厚度≥5μm,可有效防止氧化(接触电阻≤20mΩ),确保长期使用(≥500次插拔)后仍保持稳定电性能。
该产品因“小型化、高可靠”特点,覆盖多个领域:
采用SMD卧贴,贴装时可通过“定位柱+PCB焊盘”精准定位,回流焊温度曲线适配常规无铅工艺(220℃~260℃);线端对接时,带扣结构仅需轻压即可卡合,无需额外工具。
星坤作为国内连接器头部厂商,该产品通过RoHS 2.0、REACH环保认证,符合ISO9001质量管理体系;出厂前需经过“接触电阻测试、插拔寿命测试、振动测试”三道核心工序,良品率达99.9%以上。
X8821WRS-02L-LPSN以“小型化、高可靠、易生产”为核心优势,适配多种小功率设备的连接需求,是消费电子、工业控制等领域降低成本、提升可靠性的优选针座产品。

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.
