TMPC0402HP-1R0MG-Z02 功率电感产品概述

一、产品定位与核心价值

TMPC0402HP-1R0MG-Z02是台庆(TAI-TECH)推出的一款小尺寸高电流贴片功率电感,针对中高密度PCB设计中的DC-DC转换、滤波等场景,平衡了“紧凑封装”与“大电流承载能力”,是消费电子、通信设备等领域电源电路的实用选择。其核心优势在于以4.5×4.1mm的极小尺寸,实现了4.4A额定电流与8.5A饱和电流的性能,同时低直流电阻(22mΩ)减少了功率损耗,提升电源转换效率。

二、核心电气参数解析

这款电感的关键参数直接决定了应用适配性,各参数的实际意义需结合场景理解:

  1. 电感值与精度:标称1uH,精度±20%。1uH属于常用功率电感值,适配降压型DC-DC转换器(如Buck电路)的储能需求;±20%的精度满足大多数消费级/工业级电源设计的容差要求,无需额外高精度筛选。
  2. 额定电流(Irms):4.4A。这是电感持续工作时不超允许温升的最大电流(通常指25℃环境下,温升≤40℃),设计时需确保电路持续电流不超过此值,避免过热失效。
  3. 饱和电流(Isat):8.5A。指电感值下降30%时的峰值电流(即“饱和点”)。实际电路中可能存在瞬间浪涌(如开机、负载突变),此参数提供安全余量——只要峰值电流不超8.5A,电感性能不会不可逆下降。
  4. 直流电阻(DCR):22mΩ。DCR越小,电感铜损(I²R损耗)越低,电源效率越高。22mΩ的低阻值在同尺寸电感中表现优异,适合对效率敏感的便携设备(如笔记本)。

三、封装与物理特性

  • 封装类型:SMD(表面贴装),兼容主流自动化贴片生产线,生产效率高,焊接可靠性强。
  • 尺寸规格:4.5mm(长)×4.1mm(宽),属于0402级紧凑封装,厚度约2mm(台庆该系列常规参数),适配笔记本主板、路由器等窄空间PCB布局。
  • 引脚设计:采用常规SMD引脚,焊接面积合理,抗机械应力能力较好,支持回流焊、波峰焊等工艺。

四、典型应用场景

TMPC0402HP-1R0MG-Z02的参数特性决定了其适配以下场景:

  1. 消费电子电源:笔记本电脑、平板电脑、智能电视的DC-DC降压模块(如12V转5V/3.3V),满足便携设备对小尺寸、高效率的需求。
  2. 通信设备:路由器、交换机、小型基站的辅助电源电路,应对多通道电流需求,同时节省PCB空间。
  3. 工业控制:小型PLC、伺服驱动器的低功率电源部分,稳定承载4A左右持续电流,适应工业环境温湿度变化。
  4. 车载电子(通用版):车载充电器、行车记录仪的电源转换,应对汽车启动时的瞬间浪涌电流(若需车规需确认台庆对应型号)。

五、品牌与可靠性保障

台庆(TAI-TECH)作为专业电感制造商,其产品具备以下可靠性优势:

  • 工艺一致性:批量生产中参数偏差小,减少设计端兼容性问题。
  • 环保合规:符合RoHS、REACH等全球环保标准,满足市场准入要求。
  • 温升控制:针对额定电流的温升设计合理,长期工作稳定性好,降低售后失效风险。

综上,TMPC0402HP-1R0MG-Z02以“小尺寸、高电流、低损耗”为核心亮点,是电源设计中平衡性能与成本的实用选择,尤其适合对空间敏感的中功率场景。

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
