M1250R-03P线对板针座产品概述

M1250R-03P是兴飞(XFCN)推出的1.25mm间距单排3Pin弯插式线对板针座,专为小型化、高密度电子设备的信号/低功率电源传输设计,兼顾紧凑性与可靠性,广泛适配消费电子、智能家居、汽车辅助电子等场景。

一、产品核心定位与典型应用

该针座聚焦低功耗、高密度电路连接,核心解决小型设备内部“小空间+多接口”的布局痛点,典型应用场景包括:

  1. 智能家居终端:温湿度传感器、人体感应模块、智能门锁内部的信号连接(适配1.25mm间距线端,节省模块体积);
  2. 便携式电子:蓝牙耳机充电盒、智能手环主板与电池/传感器的低功率电源连接(额定1A电流满足小功率供电需求);
  3. 汽车辅助电子:座椅调节辅助控制单元、后视镜加热小模块的内部接口(工作温度-25~+85℃覆盖车载环境);
  4. 工业小型控制:微型PLC扩展接口、传感器节点的信号传输(弯插设计适配板间狭小间隙)。

二、关键技术参数详解

参数设计围绕“紧凑+可靠”核心,关键指标及实际意义如下:

  • 插针结构:1×3P(单排3Pin)→ 单排布局节省水平空间,3Pin满足常规“VCC+GND+信号”的连接需求;
  • 针距(P):1.25mm → 高密度设计,比2.0mm针距节省约37%水平空间,适配小型设备的PCB布局;
  • 安装方式:弯插(插件)→ 引脚垂直插入PCB后弯脚贴合板面,焊接牢固且抗振动性能优于直插;
  • 电气参数:额定电流1A(DC/AC通用)、额定电压125V → 满足低功率电路(≤12W@12V)的电源/信号传输,安全合规;
  • 环境参数:工作温度-25℃+85℃ → 覆盖消费类(-2070℃)与常规工业(-40~85℃)场景,无需额外降额;
  • 尺寸参数:板上高度3.2mm(Z轴)、底边宽度4.7mm(Y轴)→ 适配薄型设备内部空间,方便PCB走线与相邻针座排列。

三、结构设计与工艺特点

1. 机械结构优化

  • 弯插引脚设计:采用“垂直插入+90°弯脚”结构,焊接时弯脚完全贴合PCB板面,避免虚焊,同时提升抗振动性能(比直插引脚高约20%);
  • 紧凑外壳尺寸:单排3Pin布局,外壳宽度仅4.7mm,相邻针座可间距≤0.5mm排列,最大化PCB利用率。

2. 材料与表面处理

  • 针芯材质:优质黄铜(CuZn39Pb0.5),导电率≥56%IACS,确保信号传输损耗小;
  • 表面处理:镀锡(厚度≥3μm),耐腐蚀(通过500小时盐雾测试),焊接性优异(适配波峰焊/回流焊);
  • 绝缘外壳:耐高温PA66塑料,阻燃等级UL94 V-0,工作温度范围内无变形,常温绝缘电阻≥1000MΩ。

四、安装与兼容性说明

1. 安装注意事项

  • PCB适配:需采用1.25mm间距的过孔(孔径建议0.8~1.0mm),过孔深度≥1.5mm,确保引脚完全插入;
  • 焊接工艺:优先采用波峰焊(温度250260℃,时间≤3秒),或手工焊(烙铁温度350380℃,时间≤2秒),避免高温损坏绝缘外壳;
  • 引脚保护:安装时不要过度弯折引脚,防止针芯断裂影响连接可靠性。

2. 兼容性

  • 匹配线端:需搭配1.25mm间距的3Pin线端连接器(如兴飞同系列XFCN-1250W-03P),确保连接紧密(插拔力1~5N,符合常规操作手感);
  • PCB布局:针座周边需预留≥1mm空间,方便焊接操作与后期维护。

五、可靠性与应用注意事项

  • 可靠性测试:经过温度循环(-25℃→常温→+85℃,50次)、振动测试(10G/20~2000Hz,3h),无引脚松动、外壳变形,接触电阻变化≤5mΩ;
  • 应用余量:实际应用电流建议≤0.8A(预留20%余量),避免长期过载导致针芯发热;
  • 存储条件:未使用产品需存储在-40℃~+60℃、湿度≤85%RH的环境中,避免阳光直射与化学污染。

M1250R-03P凭借紧凑尺寸、可靠性能与成本优势,成为小型电子设备中“信号+低功率电源”连接的优选针座,适用于对空间敏感且要求稳定传输的场景。

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
