首韩1.25-3P LT线对板针座产品概述
一、产品核心定位与应用场景
这款首韩（SHOU HAN）1.25-3P LT线对板针座，属于1.25mm微间距系列，主打「小型化、高可靠性」，适配空间紧凑的电子设备。核心应用场景包括：
- 便携式消费电子：蓝牙耳机、智能手环、TWS充电盒的信号/电源接口；
- 小型家电控制板：智能插座、迷你加湿器的传感器连接；
- IoT设备模块：低功耗物联网节点（如温湿度传感器）的板端接口；
- 汽车辅助电子：小功率传感器（如胎压监测辅助接口）的信号传输。
其1.25mm间距设计能大幅节省PCB空间，满足现代电子设备「轻薄化」需求。
二、关键规格参数解析
基础参数梳理
维度 具体参数 备注说明 插针结构 1排3Pin（1×3P） 单排设计适配窄空间布局 间距 1.25mm 微间距，比2.0mm节省37%面积 安装方式 立贴（LT）SMD 无需钻孔，适合自动化贴装 电气参数 额定电流1A、电压125V 满足低功率电路需求 工作温度 -25℃~+85℃ 覆盖常规室内外环境 材质 触头黄铜+锡镀层；外壳LCP LCP为UL94V-0阻燃等级三、结构设计与材质特性
1. 触头性能：稳定导电+抗氧化
采用黄铜基材+表面镀锡：
- 黄铜导电率高（≈28%IACS），接触电阻通常<20mΩ；
- 锡镀层厚度≥1μm，可有效防止触头氧化，插拔时接触更稳定，减少信号衰减或功率损耗；
- 插拔寿命实测可达500次以上，满足多次装配需求。
2. 外壳防护：阻燃+耐温+尺寸稳定
外壳选用米色LCP（液晶聚合物）：
- 阻燃等级UL94V-0，遇明火不持续燃烧，符合电子设备安全标准；
- 耐温范围-40℃~300℃，可承受SMT回流焊（260℃峰值），高温下变形量<0.1%；
- 机械强度高，抗冲击性能优于普通ABS，避免装配时外壳开裂。
3. 立贴结构：节省垂直空间
立贴设计让针座垂直于PCB表面，高度仅5.2mm，可避免与周围元件干涉；插针端与配套线端端子（1.25mm间距）匹配紧密，插拔力约1.5N~3N，手感适中。
四、安装与适配注意事项
- 贴装工艺：需匹配回流焊温度曲线（预热150℃180℃/60s，峰值240℃260℃/10s），避免外壳熔化；
- 配套端子：必须使用同系列1.25mm间距线端端子（如首韩SH-1.25系列），禁止混用不同间距端子；
- PCB布局：预留针座周围≥1mm空间，避免焊接时锡珠短路；立贴高度需考虑PCB背面元件（若有）；
- 存储条件：未使用产品需密封存于干燥环境（湿度<60%），避免触头氧化影响焊接效果。
五、性能优势与可靠性总结
- 小型化优势：1.25mm间距比2.0mm针座节省约37%PCB面积，适合便携式设备紧凑设计；
- 环境适应性：-25℃~+85℃工作温度，可在北方冬季（-20℃）、南方夏季（35℃）稳定运行；
- 成本效益：国产首韩品牌，性能对标进口PicoBlade系列，但价格降低30%以上，适合批量生产降本；
- 安全可靠：LCP阻燃外壳+黄铜锡镀层触头，通过UL、RoHS认证，满足电子产品安规要求。
这款针座兼顾「小型化」与「可靠性」，是低功率电子设备板端接口的高性价比选择。

Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
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.
