FHD252010S-100MT 产品概述

一、基本参数

FHD252010S-100MT 为长江微电(cjiang/长江微电)出品的一款表面贴装功率电感,主要电气参数如下:标称电感值 10 µH,公差 ±20%;额定电流 750 mA,饱和电流(Isat)1 A;直流电阻(DCR)为 630 mΩ;封装为 SMD。该型号常用于中低功率电源滤波与能量储存场景,器件编号与封装适配自动贴装工艺。

二、主要特性

  • 中等电感量(10 µH)适合降噪与直流支路滤波。
  • 较高的 DCR(0.63 Ω)意味着在较大电流下会有明显的功耗与压降,设计时需考虑效率与发热。
  • 额定电流 750 mA 可满足多数小型点载或输出滤波需求,峰值不超过 1 A 以避免磁饱和。
  • SMD 封装利于表贴生产与小型化 PCB 布局。

三、典型应用场景

  • 开关电源(尤其是降压/升压转换器的输出侧或输入侧滤波)
  • 电池供电设备的能量滤波与去耦,如便携式设备、模块化电源板
  • EMI/噪声抑制、模拟电路供电净化、小功率电机驱动电路的滤波链路

四、设计与选型建议

  • 电流与热预算:按额定电流 750 mA 连续工作,器件功耗为 I^2·DCR,举例:0.75 A 时功耗约 0.75^2×0.63 ≈ 0.35 W;峰值 1 A 时功耗约 0.63 W,需预留散热余量并避免长期在峰值下工作。
  • 饱和与直流偏置:带直流偏置时电感会下降,设计中应留足裕量(建议实际工作电流控制在额定电流的 70%–90% 范围以内,具体依据系统温升与效率需求调整)。
  • 电感公差 ±20% 需要在滤波频率和谐波抑制计算中考虑,以保证在最坏情况下仍满足电路性能。

五、PCB 与焊接建议

  • 尽量缩短电感两端的连接走线,减小寄生电阻与电感。
  • 安置在散热较好的区域,避免被高发热器件包围。
  • 遵循厂家推荐的焊盘尺寸与回流焊曲线(SMD 器件一般兼容常规无铅回流工艺),贴装时注意防止元件位移及过热。

六、可靠性与注意事项

  • 避免长期超过额定电流工作以免温升导致寿命下降或磁芯退磁。
  • 高湿环境或强机械应力下需注意封装完整性,存储时遵守防潮规定。
  • 在高频应用中应评估器件的频率响应与自谐频率,必要时向供应商索取详细的阻抗-频率曲线与温升测试数据。

七、小结

FHD252010S-100MT 是一款面向中低功率应用的 SMD 功率电感,10 µH 的电感量与 750 mA 的额定电流使其在便携设备电源滤波、降噪与小功率 DC-DC 模块中具备实用价值。选型时需关注 DCR 带来的功耗与温升,并为饱和和公差留出合理裕量,以确保长期稳定可靠工作。若需更详细的频率特性与热阻数据,建议联系长江微电获取完整规格书与测试曲线。

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.
