长江微电FTC322520S6R8MBCA功率电感产品概述

一、产品基本定位

FTC322520S6R8MBCA是长江微电(cjiang)推出的贴片式功率电感,属于该品牌常规功率电感系列,主打中小功率电源场景的储能与滤波功能,以紧凑封装、低损耗和稳定电流特性为核心卖点,适配消费电子、通信、工业控制等多领域的小型化电路设计需求。

二、核心电气性能参数解析

该电感的关键电气指标明确,可直接支撑电路设计选型:

  1. 电感量与精度:标称电感值6.8μH,精度±20%,满足大多数电源电路对电感量的通用需求(无需超高精度场景下可覆盖90%以上中小功率应用);
  2. 电流承载能力:
    • 额定电流(Ir):2.8A(指电感在额定工作温度下允许的最大连续工作电流,超过该值会导致磁芯发热加剧、电感量缓慢下降);
    • 饱和电流(Isat):3.8A(磁芯开始饱和时的临界电流,此时电感量会快速下降30%以上,电路需确保瞬态峰值电流不超过此值,避免性能突变);
  3. 直流电阻(DCR):101mΩ(线圈绕线的直流电阻,值越小则铜损越低——2.8A连续工作时功耗约0.8W,散热压力小);
  4. 温度范围:典型支持-40℃~+125℃(工业级宽温设计,适配高低温环境下的稳定运行)。

三、封装与物理特性

  1. 封装规格:采用1210英制贴片封装,对应公制尺寸为3.2mm(长)×2.5mm(宽)×2.0mm(高),体积紧凑,可有效节省PCB布局空间,适合小型化产品(如超薄平板、便携路由器等);
  2. 工艺与合规性:无铅无卤设计,符合RoHS 2.0及REACH环保标准,满足全球市场准入要求;
  3. 焊接兼容性:支持常规回流焊工艺(峰值温度260℃/10秒以内),焊盘设计与行业通用1210封装一致,无需额外调整PCB layout。

四、典型应用场景

结合电气参数,该电感适用于以下核心场景:

  1. 中小功率DC-DC转换器:如12V转5V/3.3V的BUCK降压电路(电流2~3A区间),电感储能平滑输出纹波,提升电源效率;
  2. 开关电源输出滤波:配合电容构成LC滤波网络,抑制开关噪声,优化输出电压稳定性;
  3. 消费电子终端:笔记本电脑、平板、智能音箱等设备的电源模块(体积小、电流匹配);
  4. 小型通信设备:路由器、交换机、无线AP的电源单元(宽温特性适配机房环境);
  5. 工业控制电路:PLC、传感器模块的辅助电源(抗高低温冲击)。

五、设计优势与价值

  1. 电流裕量充足:饱和电流(3.8A)比额定电流(2.8A)高35%,可有效应对电路瞬态过流(如负载突变),降低故障风险;
  2. 低损耗提升效率:101mΩ的DCR在同规格1210电感中处于中等偏优水平,减少电源转换过程中的铜损,适合对效率敏感的便携设备;
  3. 宽温稳定可靠:-40℃~+125℃的温度范围覆盖绝大多数应用场景,避免高低温下电感量漂移导致的电路性能下降;
  4. 品牌品质保障:长江微电作为国内电感行业主流厂商,产品一致性好,批量供货稳定,适合量产项目。

六、选型参考要点

  1. 电感量匹配:6.8μH电感量适配100kHz~1MHz开关频率的DC-DC电路(频率过高则电感量需更小,过低则需更大),需结合电路开关频率确认;
  2. 电流验证:需明确电路最大连续工作电流≤2.8A,瞬态峰值电流≤3.8A,避免磁芯饱和;
  3. 空间适配:1210封装的尺寸需与PCB布局预留空间匹配,注意周边元件的散热间隙;
  4. 损耗核算:若对效率要求高(如便携设备),需计算DCR损耗(P=I²×DCR),确认散热是否满足需求。

总结:FTC322520S6R8MBCA是一款性价比突出的中小功率贴片电感,以紧凑封装、稳定电流特性和低损耗为核心,覆盖多领域应用场景,适合对体积、效率有要求的量产项目选型。

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
