TMPC0402HP-220MG-Z02功率电感产品概述

一、产品核心定位与典型应用

TMPC0402HP-220MG-Z02是台庆电子(TAI-TECH)针对高密度便携式电子设备电源管理推出的微型贴片功率电感,核心定位为“低损耗、高饱和、小体积”的电源电路关键元件。其典型应用覆盖三大领域:

  1. 消费电子终端:智能手机、平板电脑、智能手表的DC-DC降压模块(如5V→3.3V/1A、3.3V→1.8V/1A);
  2. 物联网边缘设备:传感器节点、蓝牙/WiFi模块、低功耗MCU的供电电路,满足“小体积+低发热”需求;
  3. 便携式医疗设备:血糖监测仪、智能手环的稳压电路,避免电感发热影响设备稳定性。

二、关键电气性能参数解析

该电感参数围绕“电源效率与稳定性”优化,核心指标解析如下:

  1. 电感值与精度:标称22uH,精度±20%,符合电源电路对电感误差的常规要求(±20%以内不会显著影响输出纹波与稳压精度);
  2. 电流承载能力:
    • 额定电流(Irms)1A:连续工作时电感值下降≤10%,保证电路输出稳定;
    • 饱和电流(Isat)1.4A:电感值下降30%的临界电流,可应对短暂过载(如启动瞬间电流波动),避免电路失效;
  3. 直流电阻(DCR):仅470mΩ,是同类微型电感的优势参数——1A连续工作时,导通损耗为(I^2R=0.47W),表面温度≤60℃,远低于同类产品平均600mΩ的损耗水平;
  4. 频率适配:支持100kHz~5MHz开关频率,匹配主流DC-DC转换器的工作范围。

三、物理封装与可靠性设计

  1. 封装规格:SMD贴片封装,尺寸4.5×4.1mm(厚度约2.0mm),兼容0402封装焊盘布局,适合高密度PCB布线;
  2. 工艺可靠性:
    • 磁芯材料:采用台庆专利“纳米晶合金磁芯”,相比传统铁氧体,饱和电流提升20%以上;
    • 线圈工艺:多层漆包线精密绕制,绕制精度±0.5匝,减少电感值偏差;
    • 封装材料:阻燃等级UL94-V0,耐高温回流焊(260℃/10s),抗振动性能符合IEC 60068-2-6标准(10~2000Hz/1g);
  3. 可焊性:无铅镀锡端子,兼容SMT自动贴装,焊接良率≥99.5%。

四、品牌与工艺优势

台庆电子(TAI-TECH)作为专注功率电感15年的台系厂商,该产品继承核心工艺优势:

  1. 材料优化:磁芯通过“纳米晶化”处理,1MHz时损耗因子≤0.05,高频损耗显著降低;
  2. 质量管控:每个电感经过“电感值测试、DCR测试、电流冲击测试”三道工序,批次一致性≥98%;
  3. 环保认证:符合RoHS、REACH标准,无铅无卤,适配全球市场需求。

五、选型匹配注意事项

  1. 适用场景:需匹配1A以内连续输出电流的电源电路,开关频率100kHz~5MHz;
  2. 避免场景:
    • 连续工作电流超过1.4A(电感饱和,输出纹波急剧增大);
    • 开关频率超过10MHz(高频损耗剧增,发热明显);
  3. 替代参考:若需更大电流,可选择同系列TMPC0503HP-220MG(额定电流1.5A);若需更小体积,可选择TMPC0302HP-220MG(3.0×2.5mm,额定电流0.8A)。

该产品以“微型化+低损耗”为核心优势,精准匹配便携式设备的电源管理需求,是小电流DC-DC电路的高性价比选择。

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
