MLG1005S13NJT000 产品概述
一、概述
MLG1005S13NJT000 为 TDK 出品的无屏蔽多层片式电感，封装为 0402（1005 公制），标称电感值 13 nH，公差 ±5%。该器件面向空间受限的高频及信号完整性应用，具有额定电流 400 mA、直流电阻（DCR）最大 260 mΩ、品质因数 Q = 8（@100 MHz）及自谐振频率（SRF）约 2.4 GHz 的特性，适用于对尺寸和频率响应有严格要求的电路设计。
二、主要特性
- 电感值：13 nH，精度 ±5%
- 额定电流：400 mA（持续电流能力）
- 直流电阻：最大 260 mΩ，有利于降低直流损耗
- 品质因数：Q = 8 @ 100 MHz，适中 Q 值适合抑制噪声与阻抗匹配
- 自谐振频率：2.4 GHz，工作频段在 SRF 以下为感性区域，SRF 以上表现为电容性
- 结构：无屏蔽多层陶瓷，封装 0402（1005）
三、典型应用场景
- 无线前端匹配网络、阻抗匹配与阻带设计（低至中频段）
- 高速数字信号线路的去耦与噪声抑制（匹配差分或单端阻抗）
- 高频滤波器、谐振电路（注意频率不超过 SRF）
- 小型化便携设备、射频模块与移动终端的电路紧凑化设计
四、选型与设计注意事项
- 工作频率应低于自谐振频率 2.4 GHz，以确保电感性行为；接近 SRF 时电感量会显著下降并出现并联/串联谐振现象。
- 额定电流应包含热升与电流去磁效应的裕量，实际应用中建议考虑温升与直流偏置造成的电感衰减，必要时降额使用。
- 无屏蔽结构对周围导体（地平面、邻近布线）敏感，布局变化会改变实际电感值与寄生电容，需在 PCB 上进行实测验证。
- Q 值仅为 8（100 MHz），在要求高 Q 的窄带滤波器中需评估是否满足性能。
五、PCB 布局与封装建议
- 采用与 0402 相匹配的焊盘尺寸，走线尽可能短且对称，避免引入额外寄生电感。
- 对于射频路径，确保器件与相连元件之间的回流路径低阻抗、短距离；尽量减少垂直层间走线跨越。
- 由于无屏蔽，避免将电感紧贴大面积金属或地平面，以免改变标称电感与 Q 值，必要时通过仿真与板上测量校正设计。
六、测试与可靠性
- 建议使用网络分析仪或可变频 LCR 仪进行频率扫描，确认电感值、Q 值与 SRF 曲线。测量时注意测试夹具的寄生参数并进行校准/去除。
- 直流电阻可用四线测量法进行精确判断，验证是否符合 260 mΩ 最大值。
- 遵循制造商推荐的回流焊接曲线，避免过高温度或长时间高温暴露；0402 尺寸易受热影响，焊接工艺需控制良好。
- 存储与操作时防潮、防机械冲击，按元器件供应商的包装与保管规范执行。
七、采购与替代
- 本料号由 TDK 提供，适合需要高可靠性、尺寸受限的工程应用。选型时可参考同类 0402 多层电感的电流、DCR、SRF 与 Q 值匹配，确保在目标频段与功率条件下性能满足需求。

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.
