顺络WPN4012H1R0MTY01功率电感产品概述

一、产品总述

顺络电子(Sunlord)推出的WPN4012H1R0MTY01是一款表面贴装(SMD)功率电感,专为中小功率电源管理电路设计。该电感采用紧凑的4×4mm封装,兼顾高电流承载能力与小型化需求,广泛适用于消费电子、物联网(IoT)终端等轻薄化设备的电源转换场景,是实现高效、稳定电源供电的核心元器件之一。

二、核心电气参数详解

1. 电感值与精度

标称电感值为1μH,精度范围**±20%**,满足常规电源电路的设计容差需求,可适配多种DC-DC转换器的滤波、储能功能,无需过度精准的匹配即可稳定工作。

2. 电流承载能力

  • 额定电流(Irms):3.6A:指电感在持续工作状态下,温升不超过行业标准(通常≤40℃)的最大均方根电流,是电路长期稳定运行的核心参考值。
  • 饱和电流(Isat):4.5A:指电感磁芯饱和时(电感值下降≤30%,行业常规标准)的最大峰值电流。若电路峰值电流超过此值,电感储能能力会显著下降,可能导致电源输出波动。

3. 直流电阻(DCR)

49mΩ的低直流电阻,可有效降低绕组铜损,减少电源转换过程中的能量损耗,提升设备续航能力(针对便携式设备),同时降低电感自身发热,延长使用寿命。

三、封装与物理特性

该电感采用SMD表面贴装封装,具体尺寸为4.0mm×4.0mm×1.2mm(对应型号后缀“4012”的行业封装定义),体积紧凑,可节省PCB布局空间,适配小型化、轻薄化设备的设计要求。

封装材料耐高温、耐焊接,兼容回流焊、波峰焊等自动化贴装工艺,适合批量生产,且焊接可靠性高,可降低生产不良率。

四、典型应用场景

WPN4012H1R0MTY01的参数特性使其适用于以下场景:

  1. 便携式电子设备:智能手机、平板电脑、智能手表等的电源管理模块(DC-DC升压/降压电路),满足低功耗、小体积需求;
  2. 物联网终端:智能家居设备(智能音箱、传感器节点)、可穿戴设备的辅助电源电路,实现稳定供电;
  3. 小型电源模块:笔记本电脑、显示器、路由器等的低压差电源(LDO)或开关电源的储能电感,提升转换效率;
  4. 工业控制小模块:小型PLC、传感器节点的电源电路,满足中小功率供电需求。

五、产品优势特点

  1. 电流性能均衡:额定电流3.6A与饱和电流4.5A的搭配,兼顾长期稳定工作与短期峰值电流耐受,适配电源电路的动态负载需求;
  2. 低损耗设计:49mΩ的低DCR大幅降低铜损,减少能量浪费,提升设备续航;
  3. 小型化适配:4×4×1.2mm封装可集成到高密度PCB布局中,支持设备轻薄化趋势;
  4. 品牌可靠性:顺络电子作为国内功率电感主流厂商,产品工艺成熟、一致性好,批量生产稳定性高,降低供应链风险。

六、选型与使用注意事项

  1. 电流限制:电路设计需确保持续电流≤3.6A,峰值电流≤4.5A,避免电感过热或性能下降;
  2. 精度适配:±20%的精度需预留设计容差,避免电感值波动影响电源输出;
  3. 焊接工艺:按照4012封装规范设计焊盘,确保回流焊/波峰焊可靠性;
  4. 温升控制:高温环境下需对电流参数降额设计,避免温升超标。

总结

顺络WPN4012H1R0MTY01功率电感凭借紧凑封装、均衡的电流性能与低损耗特性,成为消费电子、物联网等领域中小功率电源电路的优选方案。其成熟工艺与可靠品牌保障,可满足批量生产与长期稳定工作需求,是实现设备高效供电的实用型元器件。

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
