FHD252012S-R47MT 功率电感产品概述
一、产品基本信息
FHD252012S-R47MT是长江微电（cjiang）推出的贴片式功率电感，专为中小功率电源转换场景设计。产品采用表面贴装（SMD）封装，适配常规SMT自动化生产，兼具高可靠性与易集成性，是各类电子设备电源模块的理想选型。
二、核心电气性能参数
该电感的关键指标经过场景化优化，平衡了储能效率与可靠性：
- 电感值与精度：额定电感值470nH，精度±20%，常规工作条件下电感值稳定，可有效匹配开关电源的滤波、储能需求；
- 电流承载能力：额定电流（Irms）4A（额定温度下持续稳定工作的最大电流），饱和电流（Isat）5.6A（电感值下降30%时的临界电流），过流能力突出，可避免电路突发电流导致的电感失效；
- 直流电阻（DCR）：仅29mΩ，低阻设计显著降低铜损，减少自身发热，提升整机电源转换效率。
三、物理特性与封装
- 封装形式：采用贴片式（SMD）封装，尺寸标注为252012（适配常规PCB贴装），无铅环保符合RoHS指令；
- 焊接可靠性：引脚设计兼容回流焊、波峰焊等工艺，焊接不良率低，适合批量生产；
- 结构设计：磁芯绕线结构，电感一致性好，抗电磁干扰能力较强，可减少周边电路串扰。
四、典型应用场景
结合性能特点，该电感广泛适用于以下场景：
- 便携设备电源：笔记本电脑、平板、智能穿戴的DC-DC转换器，满足高效储能需求；
- LED驱动模块：小功率LED照明（台灯、氛围灯）的驱动电路，低DCR提升亮度稳定性；
- 通信设备电源：路由器、机顶盒的电源模块，小封装适配高密度PCB布局；
- 消费电子周边：移动电源、充电器，饱和电流可应对突发电流波动，提升安全性。
五、选型优势总结
- 过流能力强：饱和电流（5.6A）高于额定电流（4A），可应对电路突发电流；
- 高效低耗：29mΩ低DCR减少铜损，降低整机发热，适合便携设备；
- 集成度高：贴片小封装节省空间，便于产品小型化；
- 品牌可靠：长江微电产品质量稳定，供货周期可控，适合批量采购。
该产品通过优化电气性能与封装设计，可有效满足中小功率电源转换场景的需求，是电子设备电源模块的高性价比选型。

Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Sourcing availability signal
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
