SPM2510-4R7MD 产品概述
SPM2510-4R7MD 是长江微电（cjiang）推出的一款高性价比功率电感，标称电感值为 4.7 µH，公差 ±20%，专为小尺寸、高密度电源模块设计。元件采用贴片封装（SMD），封装尺寸 2.0 × 2.5 mm，适合移动设备、板载开关电源与信号滤波等应用场景。
一、主要特性
- 电感值：4.7 µH ±20%
- 额定电流：2.0 A（持续）
- 饱和电流（Isat）：2.6 A（规定磁通密度下降到一定比例时）
- 直流电阻（DCR）：145 mΩ
- 小型 SMD 封装：2.0 × 2.5 mm，适用于高密度 PCB 布局
- 适配回流焊工艺，便于自动化贴装与生产
二、电气性能说明
SPM2510-4R7MD 在额定电流 2 A 下能保持稳定电感特性，但应注意 DCR 为 145 mΩ，导致在 2 A 条件下 I²R 损耗约为 0.58 W，器件温升显著，需在电路热预算中考虑散热与载流能力。若短时存在较大冲击电流，可接近或达到 Isat（2.6 A），此时电感值将出现明显下降，影响开关电源纹波与稳定性，应合理预留一定余量或采取并联/更大规格器件。
三、结构与封装
本型号采用磁芯线绕结构并封装为贴片形式，体积小、厚度低，便于移动终端与消费电子中板级电源的空间优化。标准化封装兼容 SMT 贴装与回流焊工艺，对焊盘设计建议遵循厂方推荐的 PCB 爆锡与过孔布局，以保证良好可靠的焊点强度与热传导路径。
四、典型应用场景
- 同步降压/升压 DC-DC 转换器的功率滤波元件
- 模拟与数字电源轨的输出滤波与储能
- EMI 抑制和差模/共模滤波（结合其他滤波器件）
- 移动设备、物联网模块、蓝牙与射频前端的电源管理
五、选型与布局建议
- 工作电流最好低于额定电流以降低温升与避免磁饱和；建议稳态电流 ≤ 80% 额定值为佳。
- 评估纹波电流与峰值冲击，必要时使用并联器件或提升电感规格以减少损耗和温升。
- PCB 布局上靠近电源开关管与电容布局，缩短磁回路和电流环路，有利于降低 EMI 与寄生阻抗。
- 关注焊接热循环与热阻，严禁超温回流导致磁芯性能退化。
六、可靠性与质量保证
长江微电注重产品一致性与可靠性，SPM2510-4R7MD 经过常规温升、耐焊、机械振动与热循环测试。实际设计中应参考厂方最新资料与应用手册，结合自有的可靠性验证（寿命、温度循环与湿热测试）以满足终端认证需求。
七、订购与技术支持
订购型号：SPM2510-4R7MD，品牌：cjiang（长江微电）。如需批量采购或获取器件详细的尺寸图、回流曲线、频率依赖电感曲线及饱和特性曲线，请联系厂商技术支持或经销渠道获取完整数据手册与样品测试建议。

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.
