TDK MLG1005S2N2ST000 高频叠层电感产品概述

一、产品核心参数梳理

MLG1005S2N2ST000是TDK针对高频射频电路推出的叠层电感,核心参数精准适配小体积、高性能需求:

  • 电感值:2.2nH,公差±0.3nH,满足射频匹配对精度的要求;
  • 额定电流:900mA,支撑中等功率等级高频电路稳定工作;
  • 直流电阻(DCR):80mΩ,低电阻设计减少功率损耗,提升能效;
  • 品质因数(Q值):7@100MHz,常用射频频段损耗低,信号完整性好;
  • 自谐振频率(SRF):7GHz,高频特性优异,覆盖GHz级通信应用;
  • 封装规格:0402(公制1005),小体积适配高密度PCB设计;
  • 产品类型:叠层电感,采用TDK成熟叠层工艺,可靠性高。

二、设计与工艺优势

该电感依托TDK叠层电感的核心工艺,具备以下特点:

  1. 叠层结构优化:多层陶瓷基片叠层+金属线圈设计,实现小体积下的高电感密度,同时降低寄生电容,提升高频性能;
  2. 低损耗材料选型:采用低介电损耗陶瓷材料,减少高频下的能量损耗,保证Q值稳定性;
  3. 封装可靠性:0402封装符合IPC标准,焊盘适配主流SMT工艺,焊接过程中不易出现虚焊、翘曲,长期可靠性满足工业及消费电子需求。

三、关键性能亮点

  1. 高频性能突出:自谐振频率达7GHz,可覆盖5G、WLAN等GHz级通信频段,避免工作频段内电感特性突变(如电感值下降、损耗剧增);
  2. 低损耗与能效平衡:80mΩ的DCR减少直流损耗,7@100MHz的Q值降低交流损耗,射频信号传输中可有效减少衰减,提升链路性能;
  3. 电流承载稳定:900mA额定电流在小封装电感中表现优异,满足射频功率放大器、匹配网络等中等功率电路需求,额定电流下电感值变化可控;
  4. 宽温度适应性:支持-40℃至+85℃工作温度范围(TDK该系列常规参数),适配车载、户外等复杂环境。

四、典型应用场景

MLG1005S2N2ST000针对高频射频电路设计,典型应用包括:

  1. 移动通信终端:5G/4G手机、平板的射频前端(滤波器、天线匹配、功率放大器匹配),适配小体积终端设计;
  2. 无线通信设备:WLAN路由器、蓝牙模块、WiFi 6/6E设备的射频电路,利用高频性能实现信号精准匹配与滤波;
  3. 汽车电子:车载T-Box、车联网模块的射频通信部分,依托可靠性满足车载温度、振动要求;
  4. 消费电子:智能手表、无线耳机的无线充电及射频匹配电路,小封装适配可穿戴设备紧凑空间;
  5. 工业物联网:低功耗无线传感器节点的射频模块,平衡小体积与性能需求。

五、应用注意事项

  1. 频率范围匹配:实际工作频率需低于自谐振频率(7GHz),7GHz以上频段电感会表现为电容特性,无法满足电感功能;
  2. 电流裕量设计:实际工作电流应低于900mA,建议预留20%以上裕量,避免电流过载导致电感值漂移;
  3. PCB焊盘匹配:需参考TDK datasheet的0402焊盘尺寸(通常0.6mm×0.8mm),确保焊接强度,避免虚焊;
  4. 极端环境适配:若应用于-40℃以下或+85℃以上环境,需提前确认温度扩展系列的兼容性。

该产品凭借小体积、高可靠性与高频性能,成为射频电路设计中平衡性能与成本的优选方案。

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
