A3961WV-3P 产品概述

一、产品概要

A3961WV-3P 为 CJT(长江连接器)CH 系列线对板插针座,1×3P 直插(插件)结构,针间距(Pitch)为 3.96mm,单排 3PIN 设计。该产品为通孔(直插)安装方式,适用于需要可靠电气连接与较高额定电流的小型电源或信号配线场景,兼顾加工装配与成本控制。

二、主要技术参数

  • 型号:A3961WV-3P(CH 系列)
  • 插针结构:1×3P(单排 3PIN)
  • 间距(Pitch):3.96 mm
  • 安装方式:直插(通孔)
  • 额定电流:7 A(单针额定)
  • 额定电压:250 V
  • 触头材质:黄铜
  • 触头镀层:镀锡
  • 塑料材质:PA66(尼龙66)
  • 阻燃等级:UL94 V-2
  • 工作温度范围:-40 ℃ ~ +105 ℃
  • 参考系列:CH

三、产品特点

  • 稳定的电气性能:黄铜触头配合镀锡处理,导电性与焊接性良好,适合常规电源与信号传输。
  • 中等电流承载:7A 额定电流满足小型电源模块、控制板等中等功率连接需求。
  • 标准间距:3.96mm 间距为常见线对板规格,易于与市面上配套插针、母端子或接线端子匹配。
  • 结构可靠:通孔直插式安装使焊接后机械强度较好,适合振动环境下的可靠连接。
  • 阻燃与耐温:PA66 材料在常见应用温度范围内具有良好力学与阻燃特性(UL94V-2),工作温度覆盖工业级需求。
  • 成本与加工友好:镀锡触头与常见塑料材质有利于波峰/回流焊接与自动化组装,经济性好。

四、典型应用场景

  • 小型电源、适配器内部连接与出线接口。
  • 工业控制设备、继电器模块、端子排连接。
  • 家电控制板、照明驱动、电源管理模块。
  • 通用电子设备的线对板连接、测试治具以及样机连接器件。

五、安装与使用注意事项

  • PCB 设计:建议参考原厂封装图和焊盘建议,保证通孔尺寸与焊盘形状满足通孔插装与焊接强度要求。
  • 焊接工艺:镀锡触头兼容常规波峰或手工焊接,建议根据具体焊接工艺参照厂家推荐的温度曲线与时间,避免过高温度或长时间加热导致塑料件变形。
  • 防腐与可靠性:镀锡在一般环境下性能良好,如需更高耐蚀性或长寿命低接触电阻,建议选用镀金或联系厂家定制。
  • 机械应力:通孔结构承载力强,但在插拔或线束受力时仍应通过拉紧固定、绑线或固定座减轻对焊点的直接拉力。
  • 工作环境:产品适用于-40 ℃ 至 +105 ℃ 的工作温度范围,超出此范围请咨询厂家。

六、选型与包装建议

  • 若追求更高阻燃等级或耐高温性能,可向厂方询问是否有 UL94 V-0 或高温等级的替代品。
  • 对应线端或对接母座,请选用相同系列或标注兼容的连接件,确保配合插入力与插拔寿命满足应用需求。
  • 包装通常为卷装或袋装,量产时可与 CJT 确认最低包装单位、出货方式与质量检测报告。

七、资料与售后

如需详细的封装图、PCB Footprint、力学和电气测试数据(耐压、绝缘电阻、插拔寿命等)或样品获取,请联系 CJT(长江连接器)或其授权分销商索取 A3961WV-3P 的官方数据手册与物料清单(BOM)建议。购买前建议进行样件验证,确认在目标应用中的兼容性与可靠性。

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
