TDK MLG1005S18NJT000 0402贴片电感产品概述

一、基本属性与封装规格

MLG1005S18NJT000是TDK推出的小型化高频贴片电感,采用行业标准0402英寸封装(对应公制1005,即1.0mm×0.5mm),属于薄型表面贴装设计。该封装适配高密度PCB布局需求,可有效压缩终端产品体积,尤其适合便携式电子设备、小型射频模块等对空间有严格限制的场景。同时,表面贴装工艺兼容自动化贴装线,量产效率高,能降低电子设备的生产制造成本。

二、核心电气参数解析

该电感的关键指标针对性强,覆盖高频小信号电路的核心需求:

  • 电感值与精度:标称电感量18nH,精度±5%——满足射频电路对电感量一致性的要求,可避免因电感偏差导致的信号偏移或匹配失效;
  • 额定电流与直流电阻:长期稳定工作电流(Isat)350mA,直流电阻(DCR)400mΩ——低DCR设计显著降低直流损耗,减少工作发热,提升电路效率,适配小功率射频电路的电流需求;
  • 温度特性:TDK该系列电感默认支持-40℃~+85℃宽温范围(部分批次扩展至+125℃),电感值温度系数稳定,可适配工业级、消费级的宽环境应用。

三、高频性能:品质因数与自谐振特性

高频性能是该电感的核心优势,直接决定其在无线通信场景的适用性:

  • 品质因数(Q值):在100MHz频率下Q值为8——Q值反映电感的储能与损耗比,较高的Q值意味着电感在高频下信号损耗低,能保障射频信号的完整性,避免信号衰减;
  • 自谐振频率(SRF):2GHz——自谐振频率是电感由感性转为容性的临界频率,该参数表明MLG1005S18NJT000在2GHz以下频段可稳定作为感性元件使用,覆盖WiFi(2.4GHz/5GHz部分频段)、蓝牙(2.4GHz)、LTE等主流无线通信的中高频段需求。

四、典型应用场景

结合参数与性能,该电感主要适用于以下场景:

  1. 无线通信模块:蓝牙4.0/5.0模块、WiFi 6/6E模块、LTE射频前端电路,用于信号滤波、阻抗匹配网络;
  2. 便携式电子设备:智能手机、智能手表、无线耳机的射频子系统,利用0402封装节省内部空间;
  3. 高频小信号电路:GPS模块、RFID阅读器、无线充电接收端的滤波/谐振电路;
  4. 物联网与工业控制:低功耗物联网节点、工业无线传感器的射频部分,适配宽温环境与小型化设计。

五、品牌与可靠性优势

作为TDK电感系列的成熟产品,MLG1005S18NJT000具备行业领先的可靠性:

  • 参数一致性:TDK采用高精度生产工艺,电感的电感值、DCR等参数离散性小,可避免批量生产中的性能波动;
  • 抗干扰与耐候性:电感结构优化,具备一定抗电磁干扰能力,且耐受回流焊高温(260℃以上),长期工作可靠性高;
  • 环保合规:符合RoHS、REACH等全球环保标准,适配国际市场的合规要求。

综上,MLG1005S18NJT000是针对高频小型化无线通信场景的高性价比选择,参数匹配主流应用需求,封装紧凑、可靠性强,可满足消费级与工业级设备的设计要求。

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
