CJT A2543WR-3P-2线对板针座产品概述
一、产品核心定位与典型应用场景
CJT A2543WR-3P-2是一款1×3P弯插式线对板针座，专为电子设备内部的电源/信号传输连接设计，适配2.54mm标准间距。其紧凑结构、稳定电气性能及宽温耐候性，使其广泛覆盖以下场景：
- 小型家电：智能电饭煲、加湿器、扫地机器人的控制板与电源线/传感器线连接；
- 工业控制：小型PLC模块、电机驱动板、传感器节点的信号/低功率电源连接；
- 消费电子：LED台灯、蓝牙耳机充电盒、小型游戏机的内部电路连接；
- 车载小设备：氛围灯、USB充电口等低功率车载组件的内部连接（适配基础车载环境）。
二、关键参数与性能优势
2.1 电气性能参数
- 额定电流：4A（单PIN），满足多数小型设备的低功率传输需求，避免过流发热；
- 额定电压：250V（AC/DC通用），覆盖家用220V及工业低压系统；
- 工作温度范围：-40℃~+105℃，适配北方户外低温、设备内部高温散热区域，无性能衰减。
2.2 机械与结构参数
- 间距：2.54mm（0.1英寸），电子行业通用标准，兼容性极强；
- 插针结构：1排×3PIN，总PIN数3，结构紧凑，节省PCB板空间；
- 安装方式：弯插式（直角插针），适合PCB板侧面/垂直安装，灵活适配设备内部布局。
三、材料特性与结构设计优势
3.1 触头系统
- 触头材质：黄铜（高导电率+高强度），确保电流传输稳定，减少接触电阻；
- 触头镀层：锡镀层（Sn），抗氧化性能优异，插拔过程中镀层不易脱落（支持≥500次插拔），且焊接性能良好。
3.2 塑料壳体
- 材质：PA66（聚酰胺66），耐冲击、耐化学腐蚀，机械强度高；
- 阻燃等级：UL94V-0，遇明火自熄无滴落，符合电子设备安全标准，降低火灾风险；
- 耐温特性：长期工作适配-40~+105℃，焊接时（260℃以下短时间）无变形开裂。
四、安装与兼容性说明
4.1 安装注意事项
- 弯插式需确认PCB焊盘位置与角度，插针垂直插入焊盘，避免歪斜；
- 焊接温度≤260℃，单针焊接时间≤3秒，防止壳体过热变形；
- 安装后轻拉线端，确认插针与焊盘连接牢固无松动。
4.2 兼容性
- 适配2.54mm间距线端连接器（如CJT同系列线端端子），插针与线端紧密配合，接触可靠；
- 兼容其他品牌同规格（1×3P、2.54mm、弯插）线端，无需担心匹配问题。
五、品牌与品质保障
CJT（长江连接器）是国内专注连接器研发的知名厂商，产品覆盖家电、工业、汽车等领域，符合RoHS环保标准及UL安全认证（针座UL94V-0已验证）。A2543WR-3P-2经严格测试（插拔寿命、耐温老化、电气强度），品质稳定，可满足批量生产需求。
该产品以高性价比、可靠性能，成为小型电子设备内部连接的优选方案。

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.
