FTC201610S4R7MBCA 产品概述

一、产品概况

FTC201610S4R7MBCA 为长江微电（cjiang）推出的一款功率贴片电感，封装尺寸 1.6 × 2.0 mm，设计用于紧凑型电源管理和开关稳压器场合。标称电感值 4.7 μH（公差 ±20%），兼顾体积与电流承载能力，适合移动设备、物联网模组、可穿戴和小型电源模块中的输入滤波与储能应用。

二、关键电气参数

电感值：4.7 μH ±20%
额定电流（Irated）：1.6 A（持续工作建议）
饱和电流（Isat）：2.0 A（磁芯开始显著降感处）
直流电阻（DCR）：约 190 mΩ
封装：SMD，尺寸 1.6 × 2.0 mm 这些参数决定了在不同工作频率和电流条件下的效率、温升与滤波性能。

三、典型应用场景

降压（Buck）开关电源的电感元件
电源输入侧滤波、去耦与储能
移动终端、蓝牙/无线模组、电源管理芯片周边
工业与消费类低功率电源模块

四、设计与布局建议

电流裕量：建议在选择时留有余量，长期工作以额定电流 1.6 A 为基准，避免长期接近饱和电流 2.0 A。
PCB 布局：电感两端应与开关管、电容形成最短回流路径，输入/输出电容靠近器件引脚放置以降低 EMI。
热管理：高 DCR（190 mΩ）在大电流时会产生明显功耗，注意器件附近散热与走铜宽度。
焊接工艺：兼容标准回流焊；避免过度机械应力，遵循厂商推荐的焊盘和回流曲线。

五、选型与注意事项

若追求更低损耗或更高效率，可优先考虑 DCR 更低或额定电流更高的型号。
±20% 的电感公差在滤波频率计算时需考虑，影响谐振频率与滤波性能。
对于峰值较高或脉冲负载，需确认电感在脉冲条件下的电流应力与温升。
试样评估：在目标应用中进行直流偏置与温升测试，验证实际感值降低与效率影响。

FTC201610S4R7MBCA 以小型化封装和良好电流能力为特点，适合空间受限且需中等电流承载的电源设计。根据应用场景合理预留电流与热裕度，可发挥稳定可靠的电源滤波与储能功能。若需详细封装尺寸、回流曲线或可靠性数据，可联系供应商获取完整数据手册。
