【选型】长江A3501系列线对板连接器助力直流充电桩高压信号数据采集模块，额定电压达1400V

【选型】国产1.25mm间距的线对板连接器A1251WR-S-4P助力动中通天线，工作电流为1A

随着移动通信的发展，动中通天线的应用越来越广泛。本文结合某客户使用要求推荐国产长江连接器推出的A1251WR-S-4P，是一款间距为1.25mm，工作电流为1A的4pin线对板连接器，工作温度范围-40~105℃，适用于恶劣环境。

【选型】长江镀金规格线对板连接器A2010系列替代MOLEX，应用在天线驱动模块

天线驱动模块在信号输出时会用到线对板连接器，由于对传输可靠性要求较高，需要连接器触点镀金设计，某天线驱动模块项目设计阶段选用了MOLEX的532530570线对板连接器，MOLEX在交付上无法满足需求。推荐长江的A2010系列线对板连接器，触点可镀金，厚度可定制，塑壳可选PA66和LCP耐高温材料，同时引脚增加K点设计，在加工时可保证插件过波峰焊不会出现浮高，也避免了焊接倾斜的情况。

【选型】国产线对板连接器用于电脑一体机内部连接，额定电压600V，工作温度-40~105℃

某一电脑一体机内部连接需要线对板连接器，双排2x2立式座子，额定电压12V，额定电流5A，工作温度-10℃~85℃，本文根据此类需求推荐长江的C4201WV-2X2P-V0可以匹配适用。

【产品】符合UL/CUL E326732行业标准的A2509WVA-F-2xXP线对板连接器，额定电流达6.5A

长江连接器新推出的A2509系列线对板连接器A2509WVA-F-2xXP，产品间距为2.50mm。连接器塑胶外观颜色为黑色、自然色，塑胶材质为LCP，符合UL94V-0标准。此外，连接器的工作温度范围-40℃~105℃，符合UL/CUL E326732行业标准，可靠性高。

【应用】长江线对板连接器A1251用于T-BOX上检测电池电量，算上线高度不超过7mm

T-BOX项目需要一个4位的线对板的连接器去检测电池电量，通流不超过1A，因为板上空间及结构的原因只能选用直立式的规格，并且线端与板端配合后不能高于其他器件。推荐长江连接器的A1251WV-S-4P，搭配线端A1251H-4P，压线端子A1251-TP；产品间距1.25，配合高度5.93，算上线高度不超过7mm，可满足T-BOX的结构需求；同时端子最大可压接28AWG电子线，可满足1A的使用电流。
