PRODHAQ127-220M 功率电感产品概述

一、产品核心定位

PRODHAQ127-220M是谱罗德(PROD)推出的SMD贴片功率电感,专为中高电流密度的电源电路设计,兼顾电感值稳定性与电流承载能力,适配消费电子、工业控制、车载等多领域的电源转换场景。其12×12×8.0mm的紧凑封装,可在高密度PCB布局中灵活集成,满足小型化设备的设计需求,无需牺牲性能参数。

二、关键电气参数详解

该电感的核心参数清晰覆盖电源设计的关键维度,选型参考明确:

  1. 电感值与精度:标称22μH,精度±20%,满足常规电源电路对电感量的偏差要求,无需额外复杂校准;
  2. 电流承载能力:额定电流(Irms)与饱和电流(Isat)均为4.2A——这意味着在额定工作电流下,电感值无明显衰减;过载时饱和特性稳定,可避免因电感饱和导致的电路电压波动、效率下降等异常;
  3. 直流电阻(DCR):仅44mΩ,远低于同类1212封装电感的平均水平(通常50~60mΩ),可显著降低铜损,提升电源转换效率,同时减少设备发热,延长整体电路使用寿命。

三、物理封装与工艺特点

  1. 封装规格:采用SMD贴片封装,尺寸为12×12×8.0mm(长×宽×高),符合国际标准封装尺寸,可兼容主流SMT贴片机的生产流程,适合批量自动化生产;
  2. 工艺细节:磁芯采用低损耗、高饱和特性的铁氧体材质,绕线采用高导电率漆包线,紧密均匀绕制确保电感值一致性,同时降低寄生参数(如分布电容)对高频性能的影响;
  3. 引脚设计:贴片引脚采用镀锡工艺,焊接可靠性高,耐温性能符合回流焊要求(可承受260℃以上焊接温度),适配无铅制程,满足环保生产标准。

四、性能优势与典型应用

核心优势

  • 高电流密度:12×12mm封装下实现4.2A额定电流,单位面积电流承载能力突出,适合小型化电源模块;
  • 低损耗发热:44mΩ的DCR将铜损降至最低,配合高饱和磁芯,减少电源电路的热损耗,无需额外散热设计即可稳定工作;
  • 宽温适应性:谱罗德工业级品质,可在-40℃至+125℃的宽温度范围内稳定工作,满足极端环境(如车载、户外工业设备)的可靠性要求。

典型应用场景

  • 消费电子:笔记本电脑、平板的DC-DC降压转换器(如CPU供电模块);
  • 工业控制:PLC、伺服驱动器的电源滤波电路;
  • 车载电子:车载充电器、LED车灯驱动电路、车载显示屏电源;
  • 通信设备:路由器、交换机的电源模块(如POE供电滤波)。

五、可靠性与品质保障

PRODHAQ127-220M依托谱罗德的元器件制造经验,具备可靠的品质管控:

  1. 一致性管控:每批次产品经过电感值、DCR、电流承载能力的全检,参数偏差严格控制在规格范围内;
  2. 环境可靠性:通过盐雾试验(96小时,无腐蚀)、温度循环试验(-40℃~+125℃,1000次)等严苛测试,满足工业级应用的可靠性要求;
  3. 合规性:符合RoHS、REACH等全球环保指令,无铅制程,适配欧盟、北美等市场的准入标准。

该产品以平衡的性能参数、紧凑封装与可靠品质,成为中高电流电源电路的高性价比选型,可有效降低设计成本与生产难度。

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
