MF254V-11-04-0743 排母产品概述

一、产品基本定位与核心参数

MF254V-11-04-0743是兴飞电子(XFCN)推出的单排直插圆孔排母,专为中小功率电路的信号/电源连接设计,核心参数清晰匹配主流应用需求:

  • 品牌:XFCN(兴飞)
  • 排数:单排(1排)
  • 总孔位数:4P(4个独立插孔)
  • 针距(间距):2.54mm(国际通用标准,兼容性强)
  • 安装方式:直插式(插件封装,适配PCB焊接)
  • 孔型:圆孔(圆柱插孔)
  • 塑壳高度:3mm(紧凑设计,节省PCB空间)
  • 插孔方向:顶部(便于端子从上方插入连接)

该型号参数与同针距的插针/端子完全适配,可直接替代同类通用排母。

二、关键结构与工艺特点

1. 紧凑单排布局

采用1x4P直线排列,4个插孔间距2.54mm,既保证连接密度,又避免多排结构的空间占用,适合小型化设备(如便携音箱、小型传感器模组)的内部紧凑布局。

2. 圆孔接触设计

相较于方孔/扁孔,圆孔插孔为圆柱状,与匹配的圆柱插针接触时接触面积更均匀,能有效降低接触电阻波动(减少信号衰减),同时插针插入/拔出时磨损更小,延长连接器寿命。

3. 直插式封装工艺

塑壳底部带插脚,可直接焊接于PCB焊盘,适配波峰焊、手工焊等成熟工艺;插脚长度适配常规1.6mm厚PCB,无需额外加工,焊接可靠性高。

4. 低塑高设计

塑壳高度仅3mm,在保证插孔深度(满足端子插入需求)的前提下,大幅降低连接器在PCB上的高度占用,适合对设备厚度有严格要求的场景(如智能手环、车载小型模组)。

三、电气性能指标

该排母的电气性能满足中小功率电路的安全连接需求,核心指标经出厂测试符合行业标准:

  • 额定电流:3A/孔(单孔最大持续工作电流,总电流需根据实际连接数量合理分配)
  • 接触电阻:≤20mΩ(接触稳定,减少功率损耗与信号干扰)
  • 绝缘电阻:≥1000MΩ(相邻插孔/插脚间绝缘优异,避免短路风险)
  • 工作电压:≤125V AC/DC(覆盖常规低压电路应用场景)

四、环境适应性

1. 宽温工作范围

工作温度覆盖**-40℃~+105℃**,可适应寒冷地区(如北方户外设备)、高温工业环境(如烤箱、高温车间)等极端温度,不会因温度变化导致塑壳变形、接触不良。

2. 阻燃与耐候性

塑壳采用UL94V-0级阻燃工程塑料,遇明火快速自熄,降低电路起火蔓延风险;同时具备耐湿热性能,可在湿度≤90%RH的环境下长期稳定工作(符合GB/T 2423.3湿热试验要求)。

3. 振动冲击耐受

插件式结构与插脚焊接强度可靠,可承受10Hz~2000Hz振动频率、2g加速度冲击(符合GB/T 2423.10振动试验要求),适合工业控制、汽车电子等振动场景。

五、典型应用场景

MF254V-11-04-0743凭借紧凑尺寸、宽温性能与稳定连接,广泛应用于以下领域:

  1. 消费电子:小家电(加湿器、台灯)、便携设备(蓝牙音箱、智能手环)的内部信号/电源连接;
  2. 工业控制:小型PLC、传感器模组、继电器接口的辅助连接;
  3. 通信设备:小型路由器、交换机的状态指示灯接口、辅助电源接口;
  4. 汽车电子:车载小型传感器(温度/湿度传感器)、辅助电路的连接(适配汽车级宽温需求);
  5. 医疗设备:小型监护仪、血糖仪的内部信号接口(阻燃性能符合医疗安全要求)。

六、选型与使用注意事项

1. 选型匹配

  • 需确认匹配插针的针距为2.54mm、端子类型为圆柱针(圆孔排母仅适配圆柱针,避免扁针导致接触不良);
  • 若需多组连接,可选择同系列多排型号(如1x8P、2x4P),但需注意PCB布局空间。

2. 焊接注意事项

  • 手工焊:烙铁温度≤350℃,焊接时间≤3s/孔,避免过焊导致塑壳熔化;
  • 波峰焊:温度260℃±5℃,焊接时间≤3s,批量生产建议采用防变形工装。

3. 存储与维护

  • 存储环境:常温(15℃~35℃)、干燥(湿度≤60%RH),避免阳光直射;
  • 长期未使用:每6个月检查一次,若插脚氧化(发黑),可用无水乙醇擦拭后使用。

总结

MF254V-11-04-0743作为XFCN的高性价比排母,以紧凑尺寸、宽温性能、稳定连接为核心优势,适配多领域中小功率电路的连接需求,是小型化设备内部接口的优选方案。

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
