CJT A3963WV-6P是长江连接器(CJT)推出的VH系列线对板直插针座,属于1排6针(1×6P)结构,针距3.96mm。作为中功率电气连接的基础组件,它主要用于实现导线与PCB板之间的稳定导通,适配VH系列端子的插拔配合,是小家电、工业控制等领域的常用连接方案。
该针座的核心参数覆盖电气、机械、环境三大维度,满足多场景需求:
选用黄铜作为基础材质,导电率高(约28%IACS),接触电阻≤10mΩ;表面镀锡处理,抗氧化能力强,可避免长期使用中氧化层导致的接触不良,同时提升焊接兼容性(适配常规手工焊/回流焊)。
采用PA66(聚酰胺66) 工程塑料,耐温性优异(长期使用温度≤120℃),抗冲击、耐化学腐蚀,且通过UL94V-0阻燃认证,安全可靠。
针脚采用精密冲压成型,针距公差±0.05mm,确保与端子配合紧密;塑料主体注塑一体成型,无拼接缝隙,结构稳定性强。
因参数适配性强,该针座广泛应用于以下领域:
直插式设计,针脚直接插入PCB焊盘,焊接温度建议控制在260℃以内(持续时间≤3秒),避免PA66塑料过热变形。
完全适配VH系列线端端子(如VH-3.96端子),插拔配合力适中(5~10N),插拔寿命≥500次,满足多次装配需求。
针距3.96mm符合常规PCB设计规范,可直接匹配VH系列端子的布局。
该产品符合RoHS环保指令(无铅、无镉等有害物质),适配全球市场;长江连接器对其进行了振动测试(102000Hz,1g加速度)、温度循环测试(-40℃105℃,500次循环),确保长期使用稳定性。
综上,CJT A3963WV-6P凭借紧凑结构、中功率适配性与宽温可靠性,成为多领域电气连接的高性价比选择。

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.
