BM03B-SRSS-TB(LF)(SN) 线对板针座产品概述
一、产品基本定位与核心特征
BM03B-SRSS-TB(LF)(SN)是日本JST公司SH系列下的小型化线对板针座，采用立贴（SMD）安装方式，单排3Pin设计，间距1mm，专为高密度、小体积电子设备的信号与小功率电力传输打造。其核心特征可总结为：
- 辅助焊脚增强焊接可靠性；
- UL94V-0阻燃塑料提升安全性能；
- 宽温工作范围适配多场景；
- 无铅镀层符合环保要求。
二、关键技术参数详解
该针座的参数精准匹配紧凑空间与可靠连接的双重需求，具体如下：
类别 详情 电气参数 额定电流1A（AC/DC通用）、额定电压50V、工作温度-25℃~+85℃ 机械参数 单排1×3Pin、针距1mm、板上Z轴高度4.25mm、X轴底边5mm、Y轴宽度3.6mm 材料镀层 触头：铜合金+锡镀层；塑料主体：PA（聚酰胺）+UL94V-0阻燃；颜色：白色 附加设计 集成辅助焊脚，分散焊接受力提升稳定性三、结构设计与材料特性
1. 小型化单排结构
1mm针距是核心亮点——相比常规2.54mm间距针座，可节省约60%的PCB空间，完美适配智能穿戴、蓝牙耳机等超小型设备的内部布局。单排3Pin设计兼顾信号传输与小功率供电需求，避免冗余结构。
2. 辅助焊脚的可靠性提升
立贴针座依赖Pin脚与PCB的结合力，辅助焊脚通过额外焊接点分散受力，可有效降低回流焊后脱落、虚焊风险，尤其适合振动环境（如工业传感器、车载小模块）。
3. 材料的环境适应性
- 触头：铜合金基锡镀层，导电性能优异，焊接性好且抗氧化；
- 塑料：PA材料韧性强、耐温性佳，UL94V-0阻燃等级可延缓设备起火时的燃烧速度，提升安全；
- 环保特性：无铅镀层（LF标识）符合欧盟RoHS 2.0指令，避免铅污染。
四、典型应用场景与市场优势
1. 典型应用场景
- 便携式消费电子：智能手环、蓝牙耳机、充电宝的电池-主板连接、传感器信号传输；
- 小型工业控制：PLC模块、温度/压力传感器接口板的信号连接；
- 汽车电子：车载小功率控制单元（座椅调节、氛围灯）的内部连接；
- 家电控制板：智能台灯、加湿器的控制电路与功能模块连接。
2. 市场优势
- 空间效率高：1mm针距+紧凑尺寸，适配“小而轻”的设计趋势；
- 可靠性稳定：辅助焊脚+JST工艺控制，降低售后故障率；
- 装配便捷：立贴设计适配自动化SMT生产线，提升生产效率；
- 环保合规：无铅镀层符合全球标准，适合出口产品。
五、认证与合规性说明
该产品通过多项权威认证：
- 塑料阻燃等级UL94V-0（符合UL安全标准）；
- 无铅镀层（LF标识）符合欧盟RoHS 2.0、日本JIS C 5061标准；
- 整体设计满足电子设备EMC（电磁兼容性）要求，避免信号干扰。
作为JST SH系列的经典型号，BM03B-SRSS-TB(LF)(SN)凭借小型化、高可靠与环保特性，成为众多小型电子设备连接方案的优选，可覆盖消费电子、工业、汽车等多领域需求。

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.
