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。
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:
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。
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。
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)。
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:
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。

Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
