MLG1005S24NJT000 产品概述

一、产品简介

MLG1005S24NJT000 是 TDK 推出的 0402(公制 1005)贴片叠层电感,标称电感值 24 nH,公差 ±5%,额定直流电流 350 mA。该器件为高密度表面贴装元件,适合对体积和布局有严格要求的移动终端、无线模块及消费类电子产品的射频与去耦应用。

二、关键参数速览

  • 电感值:24 nH ±5%
  • 额定直流电流:350 mA
  • 直流电阻(DCR):430 mΩ(典型)
  • 品质因数(Q):8 @ 100 MHz
  • 自谐振频率(SRF):1.7 GHz
  • 封装/类型:0402 叠层片式电感(MLG)
  • 品牌:TDK

三、性能解读与工程意义

  • 自谐振频率 1.7 GHz 表明器件在高于该频率时将出现电容性行为,因此不建议在 1.7 GHz 以上工作频段作为纯感性元件使用。可可靠用于 VHF、UHF 及低 GHz 范围内的匹配、滤波与偏置网络,但不适合 2.4 GHz(Wi‑Fi/Bluetooth)等更高频应用。
  • 在 100 MHz 时,电抗 X_L ≈ 2π·100e6·24e‑9 ≈ 15 Ω,结合 Q=8 可估算该频率下的等效串联电阻约为 1.9 Ω(频率相关阻抗高于直流 DCR)。这说明高频损耗受寄生与辐射影响,若电路对损耗敏感,应在选型时评估实际插损或转移函数。
  • DCR 430 mΩ 在 0402 尺寸下属于可接受范围,但不适合承担较大电流或作为主供电电感。若用于直流偏置或电源滤波,请考虑功耗与温升。

四、典型应用场景

  • 射频阻抗匹配网络、L 型匹配元件
  • 高频去耦与共模/差模抑制(与其他被动元件配合)
  • 振荡器、谐振回路(在 SRF 范围内谨慎设计)
  • 尺寸受限的移动设备、蓝牙/低频蜂窝天线匹配、物联网模块的前端网络(频段需低于 SRF)

五、PCB 布局与焊接建议

  • 尽量缩短与电感连接的走线,减少寄生电感与电阻带来的性能退化。
  • 贴片焊盘建议采用厂商提供的推荐尺寸并遵循 0402 的焊接规范,确保良好焊接湿润和热循环可靠性。
  • 回流焊温度曲线请参考 TDK 官方资料,避免超出最大温度/时间以防晶片裂纹或性能漂移。
  • 器件在较高直流偏置下电感值会下降(直流饱和效应),设计时应留有裕量并在实际条件下验证。

六、选型注意事项与替代方案

  • 若需要在更高频段(如 2.4 GHz)保持感性特性,应选择 SRF 更高的型号或采用小电感值/专用 RF 电感。
  • 若电流要求高且对 DCR 敏感,考虑功率型电感或更大封装以获得更低 DCR 和更高电流承载能力。
  • 对于高 Q 需求的滤波器件,Q=8(100 MHz)属于中等,需权衡损耗与尺寸,必要时评估更高 Q 的陶瓷/空芯电感。

七、可靠性与测试建议

  • 在样机阶段进行温升测试、直流偏置下的电感值漂移测试及频域插入损耗测量。
  • 关注焊接热循环、机械冲击与潮湿环境下长期可靠性,按应用场景做加速老化验证。

总结:MLG1005S24NJT000 以超小体积提供 24 nH 的感值,适合尺寸受限的高频匹配与去耦应用。但在选用时需充分考虑其较高的高频等效阻抗、SRF 限制以及电流承载能力,确保在目标工作频段与电流条件下性能满足系统需求。若需更详细的封装尺寸、推荐焊盘或电磁模型,请参考 TDK 官方数据手册。

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
