TMPC0402HP-2R2MG-Z02 功率电感产品概述

一、产品核心身份与品牌背景

TMPC0402HP-2R2MG-Z02是台庆电子(TAI-TECH) 推出的一款表面贴装(SMD)功率电感,专为中等功率密度的电子电路设计。作为被动元件领域的专业产品,该电感聚焦“小体积与高电流耐受”的平衡,适配消费电子、工业控制、汽车电子等多场景的DC-DC转换、电源滤波需求,是台庆电子在功率电感领域的成熟量产型号。

二、关键电气性能参数解析

这款电感的核心参数精准匹配中小功率电路的核心需求,各参数的实际意义可清晰对应电路设计的关键要求:

  • 电感量与精度:标称2.2μH,精度±20%——满足大多数DC-DC降压/升压电路的电感量匹配需求,无需额外复杂的调试,适配宽范围的输出电压设计;
  • 额定电流(Irms):3.5A——指持续工作时电感温度上升不超过规格值(通常≤40℃)的最大电流,保证长期稳定运行,避免过热导致的参数漂移;
  • 饱和电流(Isat):6A——当电感量下降至初始值80%时的峰值电流,支持电路瞬态负载波动(如开机瞬间、负载突变),避免磁饱和导致的输出电压异常;
  • 直流电阻(DCR):51mΩ——低电阻设计大幅降低电流损耗(3.5A工作时损耗约0.62W),提升电源转换效率,减少散热片或散热空间的需求。

三、物理特性与封装规格

为适配紧凑式电路设计,该电感采用小型化SMD封装,具体尺寸为4.5mm×4.1mm(长×宽),高度符合贴片元件自动化贴装标准(约2mm,适配标准SMT生产线)。这种封装具备三大实际优势:

  1. 小体积集成:可嵌入手机、平板、小型路由器等便携设备的电源模块,不占用额外PCB空间;
  2. 自动化兼容:支持SMT(表面贴装技术)高速生产,降低组装成本与人工误差;
  3. 抗振动可靠:SMD封装与PCB板贴合紧密,适合车载电子、工业设备等对振动敏感的场景。

四、典型应用场景

结合参数与封装特性,TMPC0402HP-2R2MG-Z02的核心应用场景覆盖以下领域:

  1. 消费电子电源:手机、平板、智能手表的快充电路(将12V/9V转换为5V/3.3V),适配小体积快充模块;
  2. 小型工业电源:PLC(可编程逻辑控制器)、传感器节点的供电电路,满足低功耗、稳定供电需求;
  3. 汽车电子辅助:车载USB充电器、仪表盘小功率照明的DC转换模块,耐受-40℃~85℃的车载温度范围;
  4. 通信设备电源:路由器、交换机的小功率供电单元,适配高密度PCB布局的紧凑设计。

五、产品优势与实际价值

相比同类竞品,该电感在“性能-体积-成本”上实现了平衡,核心价值体现在:

  • 电流耐受突出:6A饱和电流远超同体积竞品(多数竞品仅3~4A),适配负载波动更大的场景;
  • 低损耗提效率:51mΩ的DCR比同类100mΩ产品减少约0.36W损耗,尤其适合对效率敏感的快充电路;
  • 可靠性稳定:台庆电子的量产工艺保障电感量一致性与DCR稳定性,长期工作无明显参数漂移;
  • 性价比高:成熟的SMD封装与量产工艺,降低了采购与组装成本,适合批量应用。

六、总结

TMPC0402HP-2R2MG-Z02作为一款中小功率SMD电感,以“小体积、高电流、低损耗”为核心亮点,精准覆盖消费电子、工业、汽车等多领域的电源电路需求。无论是追求紧凑设计的便携设备,还是需要稳定供电的工业控制,该电感都能提供可靠的性能支撑,是中小功率电源设计的优选元件之一。

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
