FTC252012S2R2MBCA 产品概述

一、产品简介

FTC252012S2R2MBCA（长江微电 cjiang）是一款表面贴装功率电感，标称电感值 2.2 μH，公差 ±20%。器件封装为 SMD，外形尺寸为 2.0 × 2.5 mm，专为高频开关电源与功率滤波场景设计，兼顾体积、热耗与磁通饱和性能。

二、主要电气参数

电感值：2.2 μH ±20%
额定电流（Irms）：3.0 A（长期允许通过的连续电流）
饱和电流（Isat）：3.8 A（电感下降到规定偏差前的最大直流偏置电流）
直流电阻（DCR）：约 55 mΩ（影响功率损耗与温升）
这些参数决定了器件在 DC-DC 降压、LED 驱动及输入输出滤波中的适用性。

三、性能特点与优势

小型封装（2×2.5 mm），便于高密度 PCB 布局与移动设备使用。
较高的额定电流和较高的饱和电流裕量，适合中小功率转换器。
适中 DCR 在兼顾损耗和热性能方面平衡良好，有助于降低开关损耗与温升。

四、典型应用场景

同步降压/升压转换器（SBC、PMIC 模块）
输入/输出滤波网络，抑制开关噪声与纹波
移动终端、通信设备与工业控制的电源管理模块
LED 驱动与电机驱动的低功率级滤波

五、使用建议与注意事项

选型时应以实际工作电流（含纹波）低于额定电流并留有裕度，避免接近饱和电流工作点。
DCR 会带来 I^2R 损耗，需评估温升并在布局中留出散热条件。
焊接采用标准回流工艺，建议参考厂方推荐焊盘尺寸与回流曲线以保证可靠性。
在高频应用中，注意与开关管、二极管的走线最小化回路面积，减小 EMI。

如需器件族参数、典型电流纹波测试曲线或推荐封装焊盘图，可提供进一步资料以便精确设计与仿真。
