A2012WR-S-2P 产品概述
一、产品简介
A2012WR-S-2P 为 CJT（长江连接器）出品的一款 2P 线对板插针座，采用 1×2P 布局，节距 P=2.00mm，卧贴式 SMD 封装。该器件体积小、低高度，适合空间受限的线对板连接场合，常用于小型电源、信号传输及消费类电子产品的线束接入。
二、主要规格参数
- 插针结构：1×2P（单排 2 PIN）
- 节距（P）：2.00 mm
- 安装方式：卧贴（SMD）
- 总 PIN 数：2P
- 额定电流：3 A（单针额定）
- 额定电压：250 V
- 触头材质：黄铜（Brass）
- 触头镀层：锡（Sn）
- 塑料材质：PA6T，阻燃等级 UL94 V-0
- 工作温度范围：-40 ℃ ～ +105 ℃
三、结构与材质特点
- 触头采用黄铜基材，保证良好的导电性与机械强度；锡镀层具有良好焊接性与抗氧化性。
- PA6T 阻燃塑料外壳在高温下保持稳定，符合常见 PCB 装配和环境要求。
- 卧贴 SMD 形式便于自动化贴装和回流焊接，利于批量生产与可靠焊点形成。
四、PCB 设计与安装建议
- 推荐按厂方推荐的 land pattern 布局设计焊盘，确保焊膏量和焊点形态良好；如无推荐图，可采用适当加长侧焊盘以增强焊接强度。
- 选用通用无铅回流工艺，遵循 PCB 与元件回流曲线，峰值温度一般不超过 260 ℃。
- 贴装时使用适配吸嘴，避免直接压迫塑料壳体；回流后建议做目检或 X-ray 检查焊点完整性。
五、应用场景
适用于需要小型、可靠线对板连接的场合，如：LED 驱动板、便携设备电源接口、家电控制板、通讯设备内部小电流电源或信号连接等。
六、使用注意事项与可靠性提示
- 在接近额定电流（3A）工作时应考虑散热与连续工作的温升影响，必要时对电流进行适当降额。
- 选用匹配线规（建议导线截面积与 3A 电流相适应，约 0.2～0.3 mm²）并保证压接或端子端接良好。
- 存储与波峰／回流焊前后应避免潮湿吸附，按元件厂商建议执行烘干或防潮措施。
- 对于需特殊认证（如高频或汽车级）应用，请向供应商确认具体版本和认证信息。
七、订购信息
- 型号：A2012WR-S-2P
- 品牌：CJT（长江连接器）
- 封装：SMD，P=2.00mm，卧贴 1×2P

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.
