Sunlord WPN4012H220MT 贴片功率电感产品概述

一、产品定位与核心场景

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。

二、关键参数详细说明

1. 电感特性

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。

2. 电流性能

  • 额定电流(Irms):900mA:该电流下电感值变化≤10%(行业常规标准),可长期稳定工作;
  • 饱和电流(Isat):1.05A:电感值下降30%时的临界电流,设计时建议留10%-20%余量,避免电路过载时性能波动。

3. 直流电阻(DCR)

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)。

4. 封装尺寸

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。

三、封装与可靠性特点

1. 自动化生产适配

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。

2. 低profile设计

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。

3. 环保与可靠性

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。

四、核心性能优势

1. 空间与电流的平衡

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。

2. 低损耗提升效率

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。

3. 稳定的磁饱和特性

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)。

4. 宽应用兼容性

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。

五、典型应用场景示例

  1. 消费电子终端:智能手机、平板电脑的DC-DC降压电路(主芯片供电、屏幕背光驱动);
  2. 便携式智能设备:智能手表、蓝牙耳机、运动手环的电源管理模块(电池输出转各功能模块电压);
  3. 物联网节点:低功耗传感器(温湿度、运动传感器)的供电电路,支持小电流、长续航需求;
  4. 微型电机驱动:小型玩具电机、智能门锁/指纹锁的微型步进电机驱动电路(电流匹配900mA左右)。

总结

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。

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
