SWPA4030S2R2NT 产品概述
SWPA4030S2R2NT 是顺络（Sunlord）推出的一款 4×4mm 封装片式功率电感，额定应用于中低功率开关电源与电源模块。其典型参数为 2.2µH ±30%，额定电流 2.95A，饱和电流（Isat）5.8A，直流电阻约 30mΩ，适合对体积、效率和电流承载有平衡需求的电源设计。
一、主要性能亮点
- 电感值：2.2µH，公差 ±30%，适合滤波与能量存储用途。
- 电流能力：额定电流 2.95A，饱和电流 5.8A，能承受短时较大电流冲击而不出现明显电感下降。
- 低损耗：DCR ≈30mΩ，有利于降低铜损与温升，提升转换效率。
- 封装与可靠性：SMD 4×4mm 小型封装，适合自动贴装与高密度设计，机械强度和抗振动性能良好。
二、典型应用场景
- 同步降压/升压 DC-DC 转换器输出电感与输入滤波。
- 电源管理模块（PMIC）、负载开关与电源分配。
- LED 驱动、电机驱动器与便携设备供电前端。
- 工业与通信设备中对空间与散热有要求的电源子系统。
三、设计注意事项
- 直流偏置下电感会下降，实际电路中应按工作电流下的有效电感值评估环路性能。
- 在接近或超过额定电流时要关注温升与长期可靠性，必要时留有裕量或并联使用。
- DCR 与功耗有关，布线应尽量缩短电流回路并加大铜厚以降低系统损耗与热阻。
四、布局与焊接建议
- 尽量将电感与开关器件、二极管或电容的接地/电源节点靠近布局，减少环路面积以降低 EMI。
- 为保证散热，PCB 使用较大铜面并适当过孔加强散热路径。
- 焊盘与回流焊工艺需遵循顺络提供的推荐回流曲线，避免过温或冷焊引起可靠性问题。
五、可靠性与选型建议
- 对于持续高电流或高温环境，建议按实际应用场景做样品验证，包括热循环、振动与老化测试。
- 若对电感公差或温升有更严格要求，可考虑公差更窄或更低 DCR 的型号，或采用并联/串联组合优化性能。
- 订购时请确认版本与包装（卷带/托盘），并参考顺络最新样本与规格书以获取完整电气与机械参数。
总结：SWPA4030S2R2NT 在尺寸与电流承载之间提供了良好折衷，适合要求体积小、效率中上且需承受瞬态大电流的电源场景。具体设计中建议依据实际工作点做电感偏置与温升验证，以确保长期稳定工作。

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.
