FCH1050-680M 一体成型功率电感产品概述

FCH1050-680M是方成(FC)品牌推出的一款中功率贴片式一体成型电感,专为开关电源、车载电子、消费电子等领域的电流滤波与能量存储设计,兼顾高可靠性、低损耗与紧凑尺寸,满足多数中功率电路的电感需求。

一、产品定位与核心特性

该电感定位于中功率直流-直流(DC-DC)转换电路的核心储能元件,核心特性包括:

  1. 一体成型结构优势:采用模压成型工艺,磁芯与线圈无间隙结合,相比传统绕线电感,EMI辐射降低30%以上,且抗振动(振动频率20-2000Hz下加速度达10g时性能稳定)、抗冲击能力更强,适合车载、工业等严苛环境;
  2. 宽电流裕量设计:额定电流3A(连续工作不超此值,电感值下降≤10%),饱和电流4A(电感值下降30%时的峰值电流),可应对电路中瞬间电流波动;
  3. 低直流电阻损耗:DCR仅159mΩ,3A连续工作时功耗约1.43W,发热可控,提升电源转换效率;
  4. 紧凑贴片封装:11.5×10.5mm的SMD封装,适配自动化贴装,节省PCB空间,适合小体积电源模块设计。

二、关键电气参数详解

  1. 电感值与精度:标称电感值68μH,精度±20%,覆盖100kHz-1MHz的常见开关电源工作频率范围,满足多数降压/升压电路的电感量需求;
  2. 电流参数:
    • 额定电流(Irms):3A(环境温度25℃时连续工作,电感值变化率≤10%);
    • 饱和电流(Isat):4A(电感值下降30%时的峰值电流,需注意电路峰值电流不超此值,避免电感饱和导致输出电压波动);
  3. 直流电阻(DCR):159mΩ(25℃时测量值),直接影响电感的铜损,数值越低则铜损越小,效率越高;
  4. 工作温度范围:常规为-40℃~+125℃(需参考品牌 datasheet 确认),适配宽温环境。

三、物理封装与结构设计

  1. 封装尺寸:SMD贴片封装,外形尺寸11.5mm(长)×10.5mm(宽)×5mm(高,常规一体成型电感高度),引脚间距符合标准贴片元件规范,支持回流焊工艺;
  2. 结构细节:磁芯采用合金粉芯(方成品牌常用)提升饱和特性,线圈为多股漆包线绕制,模压后形成致密整体,无松动,耐老化性能优于传统绕线电感;
  3. 焊接兼容性:引脚采用镀锡处理,回流焊温度曲线符合IPC标准,可与其他SMD元件同步贴装,无需额外手工焊接。

四、典型应用场景

FCH1050-680M因参数匹配性强,广泛应用于以下场景:

  1. 消费电子电源:笔记本电脑、平板电脑、智能电视的DC-DC降压模块(如19V转5V/3.3V);
  2. 车载电子:车载充电器、车机电源、LED车灯驱动的滤波电感(耐振动特性适配车载环境);
  3. 工业控制:小型PLC、传感器模块的电源电路,满足宽温与可靠性要求;
  4. LED驱动电源:中功率LED阵列(10-30W)的恒流驱动电路,储能与滤波作用;
  5. 通信设备:路由器、交换机的电源模块,低EMI特性减少对信号的干扰。

五、选型与使用注意事项

  1. 电流匹配:电路连续工作电流需≤3A,瞬间峰值电流≤4A,若超过饱和电流,电感值下降会导致输出纹波增大、效率降低;
  2. 电感值精度:±20%精度可满足多数应用,若需更高精度(如精密电源),需选择±10%或±5%规格;
  3. 散热设计:3A工作时功耗约1.43W,需在PCB上对应位置铺铜(厚度≥1oz),增加散热面积,避免局部过热;
  4. 焊接工艺:回流焊温度需控制在230℃-260℃(峰值),时间≤10秒,避免高温损坏磁芯;
  5. 环境要求:避免在强磁场、高湿度(相对湿度>90%)环境下长期使用,若需防潮,可选择带封装涂层的版本(部分方成产品可选)。

FCH1050-680M凭借一体成型的可靠性、宽电流裕量与紧凑尺寸,成为中功率电源电路的高性价比选择,适用于多数对体积、EMI与可靠性有要求的电子设备设计。

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.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
