PSPMAA0603-4R7M-ANF 产品概述
一、产品简介
PSPMAA0603-4R7M-ANF 是谱罗德（PROD）出品的一款表贴功率电感，标称电感值 4.7 μH，公差 ±20%。封装为 SMD，外形尺寸 6.6 × 7.1 × 3.0 mm，适用于空间受限但要求较高电流承载能力的电源应用。该器件强调高饱和电流与相对较低的直流电阻，适配中高功率开关电源和电源管理模块。
二、主要电气参数
- 电感值：4.7 μH（±20%）
- 额定电流（Irms）：5.5 A
- 饱和电流（Isat）：10 A（电感值在该电流下显著下降）
- 直流电阻（DCR）：40 mΩ
- 封装：SMD，尺寸 6.6×7.1×3.0 mm
说明：在额定电流工作点下的铜损约为 P = I^2·DCR = 5.5^2·0.04 ≈ 1.21 W，电压降约为 V = I·DCR ≈ 0.22 V。设计时应考虑这些损耗对温升和效率的影响。
三、典型应用场景
- 同步降压（Buck）/ 升压（Boost）DC-DC 转换器
- 多相电源和点对点（POL）模块
- LED 驱动和电机驱动电源
- 工业、通信与消费电子领域的电源管理场合（需按具体环境与认证要求选型）
四、产品特点与优势
- 高饱和电流：Isat 达到 10 A，可在短时或突发负载下保持磁通不过早饱和，提升系统稳态裕度。
- 紧凑封装：6.6×7.1×3.0 mm 的 SMD 体积利于高密度 PCB 布局。
- 中等 DCR：40 mΩ 在保证电流能力的同时兼顾成本与体积，适合效率/尺寸平衡的设计。
五、选型与使用建议
- 电流裕度：推荐工作电流低于额定电流以控制温升，设计时留有饱和裕度（通常取 Irated 的 70% 左右，或参考具体应用的峰值电流与占空比）。
- 温升评估：基于铜损估算稳态温升，并结合 PCB 散热、周围器件热源进行热仿真或实测。
- 频率匹配：适用于常见开关频率范围的中高频开关电源；高频设计请参考厂商频率特性曲线以评估有效电感值随频率的变化。
- 布局与焊接：电感应靠近开关器件和整流/滤波节点布置，走线短而粗，便于降低回路阻抗与 EMI。采用厂商推荐的焊盘布局与标准无铅回流焊工艺。
六、可靠性与处理
- 存储与清洁：遵循普通 SMD 器件的防潮与清洗规范，回流后避免超出温度循环规格。
- 机械可靠性：注意在高速贴装与震动环境中采取可靠固定与测试，避免过度弯曲基板或在焊接后施加机械应力。
- 测试建议：在样机阶段进行温升、耐热、寿命与饱和特性测试，特别关注在最大占空比与突发电流条件下的表现。

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.
