FEXU0430S4R7MBS 一体成型功率电感产品概述
一、产品定位与核心价值
FEXU0430S4R7MBS是长江微电（cjiang）推出的小体积大电流一体成型功率电感，专为高密度、低损耗的电源转换场景设计。其核心价值在于平衡了“紧凑封装”与“高功率密度”的矛盾——通过优化磁芯材料与结构，实现低直流电阻、高饱和电流及优异EMI性能，可满足消费电子、工业电源、通信设备等领域对“小空间高效供电”的需求。
二、关键电气参数深度解析
该电感的核心参数直接决定适用场景，具体解析如下：
- 电感值与精度：标称4.7μH，精度±20%，覆盖DC-DC转换器常用的1-10μH区间，无需额外匹配高精度电感，降低设计成本；
- 电流特性：
- 额定电流（Irms）6.6A：25℃环境下，电感表面温升≤40K时的最大连续电流，是长期可靠运行的核心指标；
- 饱和电流（Isat）5.8A：电感值下降至标称值70%（3.29μH）时的电流，需确保电路峰值电流不超过该值，避免饱和导致纹波增大、效率下降；
- 低损耗设计：直流电阻（DCR）仅27mΩ，同类小封装电感中处于领先水平。以5A连续电流计算，损耗仅0.675W（I²R=5²×0.027），可有效减少电源模块热耗散。
三、封装与工艺特性
- 紧凑封装：采用SMD贴片封装，尺寸4.1×4.1mm（对应行业“0430”标准，高度≤3mm），适配超薄笔记本、小型通信设备等空间受限场景；
- 一体成型优势：
- 低漏磁EMI屏蔽：磁粉芯高压一体成型，无气隙设计，漏磁比传统绕线电感低30%以上，减少对周边电路的干扰；
- 高可靠性：结构稳定，抗振动（≥10G）、抗冲击性能优异，适合工业环境或严苛场景；
- 低寄生参数：无引线设计，寄生电容/电感更小，高频性能优，适配100kHz-1MHz开关频率的电源电路。
四、典型应用场景
FEXU0430S4R7MBS的参数特性适配以下场景：
- 消费电子：笔记本、平板的CPU核心供电、内存供电模块；
- 工业电源：小型PLC、伺服驱动器、工业机器人的低功耗电源；
- 通信设备：路由器、交换机、5G小基站的POE供电、射频前端电源；
- 车载电子：若通过车规认证，可用于车载中控、仪表盘辅助电源（需结合具体认证）。
五、选型与使用注意事项
- 电流匹配：实际工作电流≤6.6A（额定），峰值电流≤5.8A（饱和），避免过热或性能下降；
- 散热设计：PCB电感下方铺铜（≥1oz）+ 散热过孔，降低热阻；
- 焊接工艺：回流焊温度≤260℃，焊接时间≤10秒，避免磁芯开裂；
- 精度需求：若需高于±20%精度（如精密模拟电路），需另选高精度电感。
该电感凭借长江微电的成熟工艺与稳定参数，成为紧凑电源设计的高性价比选择，可有效提升设备功率密度与可靠性。

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.
