CD43YP0403-470M 功率电感产品概述

一、产品定位与核心身份

CD43YP0403-470M是益嘉源(YJYCOIN)推出的非屏蔽贴片功率电感,主打小型化、低功耗电子设备的功率转换与滤波场景。作为基础型电感,它以紧凑封装和适配小电流的参数设计,成为消费类电子、物联网终端等领域的常用选型。

二、关键电气参数详解

这款电感的核心参数明确,直接匹配多数小电流电源回路需求:

  1. 电感值与精度:标称47μH,精度±20%——满足一般电源滤波、DC-DC转换的电感量要求,误差范围符合工业级基础应用标准;
  2. 额定工作电流:540mA——这是电感正常工作允许的最大连续电流,若超过该值可能导致磁芯饱和,影响电感量稳定性;
  3. 直流电阻(DCR):844mΩ——直流电阻直接影响功率损耗(P=I²×R),在540mA额定电流下,损耗约0.24W(计算:0.54A²×0.844Ω≈0.24W),小电流应用可接受;
  4. 类型:非屏蔽电感——相比屏蔽电感,成本更低、电感密度稍高,但电磁干扰(EMI)相对明显,适合对EMI要求不高的场景。

三、封装与物理特性

采用SMD贴片封装,尺寸为4.5mm×4mm×3.2mm(长宽高),属于小型化贴片电感范畴:

  • 紧凑尺寸:可轻松集成到高密度PCB布局,适配智能手环、蓝牙耳机等便携式设备的小空间;
  • 贴片工艺:兼容常规回流焊流程,生产效率高,无需额外插件工序;
  • 轻量结构:铁氧体磁芯材质,重量约0.1g,对设备整体重量影响极小。

四、典型应用场景

结合参数与封装特点,主要适用于以下场景:

  1. 小型DC-DC电源模块:5V转3.3V、3.3V转1.8V等低压差转换电路,47μH电感量满足几百kHz开关频率的滤波需求;
  2. 便携式电子设备:智能手表、蓝牙耳机、运动手环的电源回路——小尺寸适配紧凑空间,540mA电流覆盖多数低功耗芯片;
  3. 物联网终端节点:温湿度传感器、低功耗蓝牙模块的电源滤波,非屏蔽设计不影响基础EMI要求;
  4. 消费类电子配件:5W快充头、机顶盒辅助电源电路,成本优势明显。

五、选型优势与注意事项

5.1 选型优势

  • 成本可控:非屏蔽设计降低制造成本,适合批量应用;
  • 集成性好:小尺寸适配高密度PCB,减少设备体积;
  • 参数稳定:益嘉源产品一致性较好,适合量产需求。

5.2 注意事项

  • EMI敏感场景谨慎选:医疗设备、高精度仪器等对EMI要求高的场景,建议换屏蔽电感,或布局时远离射频模块;
  • 避免过流:额定电流为连续值,瞬间脉冲电流需控制在饱和电流范围内(需参考厂商 datasheet);
  • 温度影响:铁氧体磁芯电感量随温度略有下降,高温场景需验证性能稳定性。

整体来看,CD43YP0403-470M是一款高性价比小电流贴片功率电感,适合多数低功耗、小型化电子设备的基础功率回路设计,是工程师选型的常用基础款。

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
