MLG1005SR18JTD25 产品概述
一 产品概述
MLG1005SR18JTD25 为 TDK 出品的贴片电感（0402 尺寸），感值 180 nH，公差 ±5%，额定直流电流 150 mA，直流电阻（DCR）2.88 Ω，品质因数 Q=8（@100 MHz），自谐振频率（SRF）约 500 MHz，符合 AEC‑Q200 车规等级。该器件针对空间受限、对高频阻抗有要求的滤波与阻抗匹配应用设计。
二 主要参数（快速一览）
- 感值：180 nH ±5%
- 额定电流：150 mA
- 直流电阻：2.88 Ω
- 品质因数：8 （@100 MHz）
- 自谐振频率：≈ 500 MHz
- 尺寸/封装：0402（MLG1005）
- 认证：AEC‑Q200（车规）
三 特性与优势
- 小型化 0402 尺寸，适合高密度贴片布局。
- SRF ≈500 MHz，使其在数百 MHz 范围内仍有较好阻抗表现，适用于高频 EMI 抑制与射频链路的阻抗控制。
- 车规等级保证了可靠性与温度循环、振动等严苛环境下的稳定性。
四 典型应用
- 高频滤波器、共模/差模滤波和射频阻抗匹配。
- EMI 抑制网络、信号线去耦与传输线终端处理。
- 汽车电子中的传感器接口、通信模块与车载信息娱乐系统。
五 选型要点与限制
- DCR 较高（2.88 Ω），这意味着在直流或低频大电流应用中功耗与发热较大，因此不适合作为大电流能量储存用感。更适合作为高频阻抗元件或滤波用。
- 若应用要求更小的损耗或更大电流，应考虑更低 DCR 或更高额定电流的型号（如更大封装或其他结构的电感）。
- 检查 SRF 与目标工作频率关系，避免工作频率接近或超过自谐振点。
六 PCB 布局与焊接建议
- 建议遵循 TDK 推荐焊盘和回流焊工艺，控制回流峰值温度在无铅工艺规范范围内（参考器件数据表）。
- 0402 尺寸器件对焊盘尺寸与锡膏打印量敏感，需优化以避免虚焊或桥连。
- 对敏感射频线，尽量缩短走线并保持良好接地以降低干扰。
七 可靠性与车规说明
- 符合 AEC‑Q200 代表通过了汽车电子常用的温度循环、湿热与机械应力试验，适用于车载环境。
- 建议在关键车载用途中参考完整的认证报告与批次可靠性数据，进行焊接后电特性验证。
八 小结与建议
MLG1005SR18JTD25 是一款面向高频滤波与 EMI 抑制的车规级小型贴片电感，优势在于小体积与在数百 MHz 范围内的阻抗特性。选型时需注意其较高的 DCR 和较小的额定电流，避免用于需大电流低损耗的电源储能场合。具体应用与工艺参数建议以 TDK 官方数据手册为准，并在样机阶段进行实测验证。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
