WPN4020H100MT 产品概述
一、产品简介
WPN4020H100MT 是顺络（Sunlord）推出的一款功率型贴片电感，规格为 10 μH，公差 ±20%，额定电流 2 A，饱和电流（Isat）3.5 A，直流电阻（DCR）216 mΩ。封装为 SMD，尺寸 4 × 4 mm，适用于空间受限且需承载中等电流的开关电源与滤波电路。
二、主要电气参数
- 电感值：10 μH（±20%）
- 额定电流：2 A（长期允许工作电流）
- 饱和电流：3.5 A（磁性材料开始显著降额）
- 直流电阻（DCR）：216 mΩ（功耗与温升参考）
- 封装：SMD，4 × 4 mm
- 品牌：Sunlord（顺络）
三、产品特点与优势
- 小体积：4×4 mm 封装，便于高密度 PCB 布局。
- 中等功率能力：额定 2 A，饱和电流 3.5 A，适合多数降压转换器与电源模块应用。
- 稳定性：材料与绕制工艺保证在额定条件下具有良好的电感稳定性与重复性。
- 易于自动贴装：适合 SMT 贴片与回流焊工艺，利于量产。
四、典型应用场景
- 降压（Buck）开关电源输出滤波
- 电源模块（模块化 DC-DC）内部滤波与储能
- LED 驱动电源与便携设备电源管理
- EMI 滤波器与电源输入侧降噪
五、使用建议与 PCB 布局
- 工作电流建议接近或低于额定 2 A，以减少电感值因直流偏置而下降及降低发热。对短时浪涌电流应确保不超过 3.5 A（饱和阈值）。
- DCR 为 216 mΩ，直流损耗不可忽视，设计时计算功耗并预估温升。
- 布局时将电感置于开关元件与输出电容之间，走线尽量短且宽，输入、输出回路环路面积最小化以降低 EMI。
- 采用厂方推荐的焊盘与回流参数（详见数据手册）以保证焊接可靠性；贴装后避免在器件上施加机械应力。
六、可靠性与质量注意事项
- 在高温环境或长期大电流工作时，关注电感温升与磁性能漂移。
- 建议在最终产品中进行热测与电流回路验证，确认在目标工况下电感值与 DCR 在可接受范围内。
- 标准静电防护与 SMT 贴装防潮措施，遵循生产厂商的存储和回流焊建议。
七、选型对比与替代建议
- 若需更低 DCR 或更大额定电流，可考虑同系列更大尺寸或专为高电流设计的功率电感。
- 若空间更受限，可检视其他封装或采用多相方案分担电感负载。选型时权衡电感值、饱和电流与 DCR 三者关系。
八、备注与采购
WPN4020H100MT 适用于需在有限空间内实现中等功率滤波与储能的应用场景。最终选型请参考顺络官方数据手册获取详细的电气特性曲线、推荐焊盘与回流曲线，并在样机阶段完成热与电磁兼容性验证。

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.
