MLG1005S12NHT000 — TDK 0402(1005)贴片电感 产品概述

本产品为 TDK 系列超小型贴片电感,封装为 0402(1005 公制),电感值 12 nH,公差 ±3%,额定电流 400 mA,直流电阻(DCR)约 250 mΩ,品质因数 Q = 8(@100 MHz),自谐振频率(SRF)约 2.5 GHz。该器件适用于体积受限的高频电路与滤波、阻抗匹配等场合,兼顾射频性能与小尺寸封装的应用需求。

一、关键参数扫瞄

  • 型号:MLG1005S12NHT000(TDK)
  • 封装:0402(1005 公制)
  • 电感值:12 nH ±3%
  • 额定电流:400 mA(最大连续直流大致值,参考应用需留裕度)
  • 直流电阻(DCR):约 250 mΩ
  • 品质因数:Q = 8(测试条件:100 MHz)
  • 自谐振频率(SRF):约 2.5 GHz
  • 适用温度与可靠性:依据 TDK 标准工业等级(具体见厂商数据表)

二、产品特性与优势

  • 超小封装:0402 封装利于高密度 PCB 设计,可用于空间受限的移动设备与模组。
  • 高频性能良好:在 100 MHz 附近拥有 Q=8 的品质因数,支持射频和中频滤波或阻抗控制应用。
  • 低直流电阻:约 250 mΩ 的 DCR 在保持电感值的同时,减小功耗和电压降,适合有一定电流需求的电路。
  • 高 SRF:自谐振频率 ~2.5 GHz,使器件在多 GHz 频段前仍能保持感性特性,适合射频前端或滤波网络。
  • 精度较高:±3% 的公差适合对频率、相位或阻抗有较高要求的匹配电路。

三、典型应用场景

  • 射频前端:匹配网络、径向线与带通/带阻滤波器中的感性元件。
  • EMI/信号完整性:高频噪声滤除、共模/差模滤波设计中的元件。
  • 时钟与射频模块:用于谐振、阻抗调节或旁路与负载隔离。
  • 消费电子:手机、无线模组、蓝牙/Wi‑Fi 天线匹配等体积受限场合。
  • 工业与汽车电子(在符合相应温度与可靠性认证前提下)。

四、PCB 布局与封装安装建议

  • 焊盘设计:遵循厂商推荐的 0402 焊盘规则,保证焊盘长度与焊膏印刷一致,避免过量焊膏造成焊点短路或偏位。
  • 引脚对齐:元件中心对准焊盘中心,减少热应力与机械应力集中,保证回流焊后接触可靠。
  • 地平面与隔离:在射频路径中合理安排地平面与过孔,避免不必要的寄生电感与寄生电容影响性能;必要时使用阻抗控制走线。
  • 热路径:若器件承载接近额定电流,保证附近有良好的散热路径以降低温升。

五、回流焊与可靠性处理

  • 回流温度:建议按无铅焊接标准(如 J-STD-020)执行的回流曲线,峰值温度一般不超过 260°C,具体以生产线和焊锡材料为准。
  • 焊接次数:遵循器件允许的最大回流次数(参考 TDK 数据表),避免多次高温循环导致性能漂移。
  • 存储与搬运:防潮防尘,避免强酸强碱环境与机械冲击;贴片器件易受应力影响,搬运时应轻拿轻放。
  • 电流与温升:推荐在设计时留有裕量(例如在额定电流下的 70~80% 工作点)以降低热应力、避免磁饱和及非线性效应。

六、测试与质量验证建议

  • 参数测量:使用网络分析仪或 LCR 表在实际工作频段进行电感、Q、SRF 与阻抗测量;在器件级和 PCB 级都应验证。
  • 温漂测试:在高低温循环与高湿环境下验证电感值和 DCR 的漂移情况,确保满足系统可靠性需求。
  • 振动与机械强度:对汽车或工业类应用,进行机械振动和冲击试验以验证焊接可靠性与长期稳定性。

七、选型与采购注意事项

  • 若系统对直流损耗或 Q 有更高要求,可考虑更大尺寸或更高规格的型号;若工作频段接近或超过 SRF,需改用更高 SRF 的产品或改用传输线匹配方案。
  • 订货信息请以 TDK 官方数据表和料号为准,批次差异、测试条件或版本更新可能影响某些参数;关键设计应获取最新数据表并与供应商确认样品测试结果。

如需我为您的具体电路(例如匹配网络或滤波器)给出更具体的仿真参数、 PCB 焊盘尺寸建议或热升分析,请提供工作频段、允许电流与板级空间等信息,我可以基于这些条件给出针对性的设计建议。

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
