WPN4012H220MT是顺络电子(Sunlord)推出的小型化贴片功率电感,针对低压直流电源转换、储能及滤波需求设计,兼顾体积紧凑性与电流承载能力,适用于消费电子、便携式智能设备、物联网节点等对空间和功耗敏感的场景,是量产级电源电路的高性价比选择。
标称电感值为22μH,精度±20%,满足大多数低压电源电路的储能与滤波要求(如DC-DC降压转换器的输出滤波),无需额外高精度筛选即可适配量产需求。
典型值为566mΩ,远低于同规格普通电感,可减少铜损导致的能量损耗,提升电源转换效率(尤其针对电池供电的便携设备,有助于延长续航)。
采用SMD 4×4mm封装(行业标注为“4012”,即4.0mm×4.0mm×1.2mm),属于小型化贴片封装,适配高密度PCB布局,可有效节省设备内部空间。
SMD封装支持回流焊工艺,兼容主流电子制造产线,焊接一致性好,可降低量产不良率。
4×4mm紧凑尺寸+1.2mm低高度,可适配超薄便携设备(如智能手表、蓝牙耳机)的PCB空间限制,无需牺牲性能换体积。
符合RoHS无铅环保标准,通过高低温循环(-40℃~+85℃)、湿度测试(85%RH/40℃) 等可靠性验证,可满足消费级及部分工业级应用的环境要求。
在4×4mm小封装下实现900mA额定电流,覆盖常见低压电源(如5V转3.3V/1A)的需求,无需通过增大封装换取电流能力,适配便携设备的小型化趋势。
566mΩ的DCR可降低电源模块的发热,避免设备因热量累积导致的性能下降,尤其适合电池供电的低功耗场景。
1.05A饱和电流提供足够设计余量,避免电路瞬间过载时电感值骤降,保障输出电压稳定(如DC-DC转换器的输出纹波控制)。
22μH电感值适配降压/升压转换器、EMI滤波、微型电机驱动等多种电路,精度±20%可满足大多数量产需求,无需针对不同场景更换型号。
WPN4012H220MT通过紧凑封装、平衡的电流能力与低损耗设计,成为消费电子及便携设备电源电路的高性价比选择。顺络电子的品牌可靠性进一步保障了量产一致性与应用稳定性,适合对成本、体积、性能均有要求的量产项目。

Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
