PRODHAQ104R-470M功率电感产品概述

PRODHAQ104R-470M是谱罗德(PROD)推出的贴片式功率电感,针对中低功率DC-DC转换、电源模块等场景优化设计,兼具电流稳定、低损耗、小型化等核心优势,可满足消费电子、汽车电子、工业控制等领域的多样化需求。

一、核心定位与典型应用

作为额定电流2.1A的功率电感,其定位是小功率电源电路的储能/滤波核心,重点解决DC-DC转换中电感饱和导致的效率下降问题,典型应用场景包括:

  • 消费电子:移动电源(2.1A输出匹配常见快充规格)、无线充电器、智能穿戴设备(手表/耳机充电模块);
  • 汽车电子:车载USB充电口、仪表盘辅助电源、小型车载传感器供电;
  • 工业控制:小型PLC的DC-DC电源模块、物联网设备低功耗供电;
  • LED驱动:小功率LED灯带、台灯、氛围灯的恒流驱动电路。

二、关键参数解析

PRODHAQ104R-470M的核心参数直接反映性能边界,各参数的实际价值如下:

1. 电感值与精度

  • 标称电感:47μH;
  • 精度:±20%(实际范围37.6μH~56.4μH);
  • 价值:满足中低精度功率电路需求,无需额外校准,降低设计复杂度。

2. 电流特性

  • 额定电流(Irms):2.1A(连续工作时,电感温升不超过允许值);
  • 饱和电流(Isat):2.1A(电感值下降30%的临界电流);
  • 核心优势:额定电流与饱和电流一致,2.1A负载下无明显电感衰减,避免输出电压波动,电路稳定性更高。

3. 直流电阻(DCR)

  • 标称值:148mΩ;
  • 价值:低DCR意味着铜损(I²R)小——以2A负载为例,铜损仅≈0.59W,远低于高DCR电感,提升电源转换效率,减少散热需求。

4. 封装尺寸

  • 规格:10mm×10mm×4mm(SMD贴片式);
  • 价值:紧凑体积适配高密度PCB设计,支持回流焊/波峰焊,提升生产效率,满足便携式设备小型化需求。

三、工艺与性能优势

PRODHAQ104R-470M采用绕线式功率电感工艺,核心特点如下:

  1. 磁芯优化:采用低损耗铁氧体磁芯,减少涡流损耗与磁滞损耗,进一步提升效率;
  2. 绕线设计:多股漆包线绕制(可选),降低高频趋肤效应影响,优化宽频性能;
  3. 可靠性:贴片焊盘符合IPC标准,焊接一致性好,适配批量生产;
  4. 平衡性能:在电流稳定性、损耗、体积之间找到最优解,无需牺牲某一维度性能。

四、选型与使用注意事项

为确保电路稳定,选型时需注意以下几点:

  1. 电流匹配:负载最大电流需≤2.1A,过流会导致电感饱和或温升过高;
  2. 精度适配:±20%精度仅适用于对电感值要求不苛刻的场景,高精度滤波需换±10%及以上规格;
  3. 封装兼容:需确认PCB焊盘尺寸与10×10×4mm匹配(参考谱罗德官方datasheet);
  4. 温度范围:车载等高温场景需确认产品工作温度(部分型号支持-40℃~125℃)。

总结

PRODHAQ104R-470M是一款高性价比贴片功率电感,针对中低功率电源电路的核心需求优化设计,兼具电流稳定、低损耗、小型化等优势,可广泛应用于多领域。其平衡的性能表现与可靠的品牌品质,使其成为电源设计工程师的实用选择。

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
