SWPA5020SR47NT 产品概述
一、产品简介
SWPA5020SR47NT 是顺络（Sunlord）推出的一款功率电感，电感值为 470 nH，公差 ±30%。采用 SMD 封装、5×5 mm 尺寸，面向高电流、要求低直流电阻的开关电源和电源管理应用设计。该器件以较低的 DCR 和较高的饱和电流特性，兼顾能效与磁性能，适合集成度较高的电源模块。
二、主要参数
- 电感值：470 nH（±30%）
- 额定电流：4.6 A（Idc，长期允许通过电流，受温升限制）
- 饱和电流 Isat：6.15 A（厂家定义的饱和点指标）
- 直流电阻 DCR：约 13 mΩ（低损耗，利于提升转换效率）
- 封装：SMD，尺寸 5×5 mm
- 品牌：Sunlord（顺络）
（更多电气温度特性与频率响应请参见厂商数据手册）
三、性能特点
- 高频性能良好，适用于开关频率较高的降压/升压转换器。
- 低 DCR 降低铜损，提升系统效率并减少发热。
- 较高的 Isat 提供良好的抗饱和能力，在大电流瞬态下保持电感特性稳定。
- 紧凑 5×5 mm 尺寸利于高密度 PCB 布局与模块化设计。
四、典型应用
- 同步/非同步降压（Buck）转换器电感
- 电源管理模块（PMIC）、VRM、POL 模块
- LED 驱动、电池管理与充电器
- 工控、通信电源及需高瞬时电流的负载供电场景
五、设计与布局建议
- 将电感尽量靠近开关器件和二极管/电感输入端放置，以缩短高频回流环路，降低 EMI。
- 多孔过孔（via）用于散热并减小回路阻抗；避免在电感下方布置敏感模拟信号。
- 考虑电感容差 ±30% 对输出滤波与环路补偿的影响；在要求精度高的场合，需在电路中预留调整空间。
- 避免长期工作在或超过 Isat 水平，以防电感值下降导致输出纹波或控制不稳定。
六、封装与可靠性
封装为 5×5 mm SMD 适合自动贴装与回流焊流程。器件采用符合行业焊接工艺的外形与焊盘建议，具体回流温度曲线、湿敏等级与可靠性认证请参考顺络官方数据手册与应用说明。
七、选型注意事项
- 若系统对电感值稳定性、输出纹波或环路带宽有严格要求，应评估 ±30% 公差的影响，或选择公差更紧的型号。
- 对于更高电流或更低 DCR 的需求，可比较同系列或其它厂商更大尺寸型号；但需权衡占板面积与成本。
- 在关键热环境下，关注器件工作温升与散热条件，必要时做实测验证。
总结：SWPA5020SR47NT 以 470 nH、低 DCR（≈13 mΩ）和较高饱和电流（6.15 A）为特点，适合多数中高电流、紧凑型电源应用。选型与最终布局请结合具体工作频率、纹波容忍度与热管理一并验证。

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.
