PRODHAQ127-390M功率电感产品概述

PRODHAQ127-390M是谱罗德(PROD) 推出的一款中小功率贴片功率电感,针对DC-DC降压电路、车载电子、工业控制等场景优化设计,具备电流能力匹配、低损耗、封装紧凑等特点,可满足量产化电源设计的稳定性与成本控制需求。

一、产品核心定位与典型应用场景

该电感定位于1-5A中小功率电源系统,主要应用于以下场景:

  1. 车载电子:中控屏辅助电源、车灯驱动模块、车载充电器(QC3.0/PD协议)等;
  2. 工业控制:PLC(可编程逻辑控制器)电源模块、伺服驱动器辅助电路、传感器信号滤波;
  3. 消费电子:机顶盒/路由器电源、笔记本电脑适配器(副路)、智能家电控制板;
  4. 通信设备:小型基站电源、无线AP电源模块。

其3.5A的电流能力可覆盖多数中小功率设备的电源需求,无需额外并联电感,简化电路设计。

二、关键电气性能参数解析

PRODHAQ127-390M的核心参数经过针对性优化,具体解析如下:

  1. 电感值与精度:标称39μH,精度±20%(实际范围31.2μH~46.8μH)。该精度在功率电感中属于常规商用级,满足量产中电感值波动的设计冗余,同时降低制造成本;
  2. 电流能力:额定电流(Irms)3.5A,饱和电流(Isat)3.5A。饱和电流定义为电感值下降至初始值70%时的电流,此款电感的额定电流与饱和电流一致,意味着负载电流超过3.5A时,电感储能能力急剧下降,会导致电源纹波增大、效率降低,设计需严格限流;
  3. 直流电阻(DCR):73mΩ(典型值)。DCR越低直流损耗越小,3.5A电流下损耗约( P=I^2R=3.5^2×0.073≈0.89W ),在1212封装中属于低损耗水平,可有效减少设备发热;
  4. 工作温度:-40℃~125℃,满足车载、工业等宽温环境需求。

三、物理封装与工艺特性

  1. 封装规格:SMD贴片封装,尺寸12×12×8.0mm(长×宽×高)。1212是功率电感主流尺寸,占用PCB面积仅144mm²,高度8mm适配多数设备内部空间(避免与其他器件干涉);
  2. 工艺设计:采用高品质铁粉芯磁芯(平衡成本与性能),线圈为多股漆包线绕制(减少集肤效应损耗);引脚镀锡抗氧化,兼容260℃回流焊温度(满足SMT自动化生产);
  3. 可靠性:经过振动(102000Hz,1.5G)、温度循环(-40℃125℃,500次)测试,可确保恶劣环境下长期稳定工作。

四、产品性能优势与设计亮点

  1. 参数匹配性:39μH电感值适配12V转5V、24V转12V等常见DC-DC拓扑,3.5A电流覆盖多数中小功率负载,无需并联电感简化布局;
  2. 低损耗高效能:73mΩ DCR降低电源转换热损耗,可使DC-DC效率提升1%~2%;
  3. 紧凑空间节省:1212小尺寸适合高密度PCB布局(如车载中控、小型通信设备);
  4. 成本可控:±20%精度与铁粉芯工艺平衡性能与成本,适合量产项目成本控制;
  5. 品牌保障:谱罗德具备稳定供货与质量管控,支持样品测试与批量供货。

五、应用注意事项与选型建议

  1. 电流限制:负载电流需≤3.5A,若需更大电流(如4A),建议选额定5A的升级款;
  2. PCB设计:引脚焊接需牢固(避免虚焊增大接触电阻),可在电感下方预留散热过孔(PCB厚度≥1.6mm时);
  3. 温度降额:环境温度超100℃时,电流需降至3A以内,避免磁芯性能衰减;
  4. 精度需求:若需±10%精度,可选择对应型号或联系谱罗德定制;
  5. 存储条件:未使用电感需存于湿度≤60%的干燥环境,避免引脚氧化影响焊接。

PRODHAQ127-390M凭借平衡的性能与成本优势,成为中小功率电源设计的优选电感,广泛适配车载、工业、消费电子等多领域量产需求。

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
