TAI-TECH台庆TMPC1707HP-220MG-D功率电感产品概述

一、产品基本信息

TAI-TECH(台庆)TMPC1707HP-220MG-D是一款SMD贴片功率电感,专为中大功率电子电路设计,属于台庆功率电感系列中的经典型号。该产品采用表面贴装封装,适配自动化生产流程,同时兼顾小型化与高电流承载能力,广泛应用于电源转换、车载电子等场景。

二、核心电气参数详解

2.1 电感值与精度

电感标称值为22uH,精度等级为±20%,满足大多数功率电路对电感量的常规精度需求(如开关电源、DC-DC转换器的滤波/储能环节),无需针对过高精密场景设计,兼顾成本与性能。

2.2 电流承载能力

  • 额定电流(Irms):12A:指电感在25℃环境温度下,能持续稳定工作的最大电流(交流/直流均可),此时电感不会因铜损/磁损过热损坏,是电路选型的核心工作电流指标。
  • 饱和电流(Isat):23A:指磁芯开始饱和时的电流值(通常以电感量下降30%作为饱和判定标准)。该参数远高于额定电流,为电路提供2倍以上的电流裕量,可应对启动浪涌、瞬时过载等场景,避免电感性能突变。

2.3 直流电阻(DCR)

直流电阻为25.1mΩ,属于低损耗设计:12A电流下的铜损仅约3.6W(P=I²×R),能有效降低电路功耗,提升电源转换效率,同时减少散热需求,延长设备使用寿命。

三、封装与典型应用场景

3.1 封装特性

采用SMD表面贴装封装,体积紧凑,可直接通过SMT设备贴装于PCB板,适配现代电子设备的小型化趋势,节省PCB空间。

3.2 典型应用

该电感因高电流、低损耗特点,广泛应用于以下场景:

  • 开关电源:服务器电源、工业电源的Buck/Boost电路(如12V转5V大电流输出);
  • 车载电子:汽车充电桩、车载DC-DC转换器(24V转12V/5V等);
  • 通信设备:基站电源模块、路由器/交换机的电源单元;
  • 消费电子:65W以上大功率快充充电器、LED驱动电源(如大功率照明驱动)。

四、性能优势分析

  1. 高电流裕量:饱和电流23A是额定电流的1.9倍,瞬时过载能力强,提升电路可靠性;
  2. 低损耗设计:25.1mΩ的DCR大幅降低铜损,适配对效率要求较高的电源电路;
  3. 宽温稳定性:常规工作温度范围(-40℃~125℃),满足工业/车载等严苛环境需求;
  4. 贴片兼容性:SMD封装适配批量生产,与主流PCB设计兼容,降低生产难度。

五、选型与使用注意事项

  1. 电流裕量预留:建议实际工作电流不超过额定电流的80%(即≤9.6A),避免长时间过热;
  2. 温度影响:电感DCR随温度升高而增大,额定电流会随环境温度(如高于85℃)降低,需参考datasheet的温度-电流曲线;
  3. 避免饱和工作:长时间工作在饱和电流附近会导致电感量下降,影响电路滤波/储能效果;
  4. PCB布局优化:需确保电感焊盘散热良好,避免靠近发热元件(如MOS管、变压器),防止温度叠加。

该产品凭借高性价比与稳定性能,成为中大功率电路中功率电感的优选型号,可满足多数工业、车载及消费电子场景的需求。

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
