MLG0603P56NJT000 产品概述

一、产品简介

TDK MLG0603P56NJT000 是一款超小型贴片电感,标称电感值 56 nH,公差 ±5%,额定直流电流 100 mA。封装标注为 0201(用户资料标注为 0603 公制),适合对体积要求极高的便携式和高速射频电路。器件直流电阻(DCR)为 2.35 Ω,品质因数 Q = 10(@300 MHz),自谐振频率(SRF)约 1.4 GHz。

二、主要特性

  • 电感:56 nH,±5%
  • 额定电流:100 mA(需按温升与散热条件参照实际应用)
  • 直流电阻(DCR):2.35 Ω(典型值)
  • 品质因数:Q = 10 @ 300 MHz(反映 高频下损耗特性)
  • 自谐振频率:1.4 GHz(高于此频率器件将呈现电容性)
  • 封装:0201(小尺寸,便于高密度布板)
  • 适用场景:射频匹配、滤波、阻抗调整与 EMI 抑制等

三、电气性能解读(要点)

  • 在低频时器件以电感特性为主,但由于较高的 DCR,直流及低频损耗不容忽视。
  • 在 300 MHz 时,感抗 XL = 2πfL ≈ 105.6 Ω;结合 Q = XL / Rseries,可估算此频点等效串联电阻约 10.6 Ω,表明高频额外损耗(磁滞损耗、涡流等)会显著高于直流 DCR。
  • SRF = 1.4 GHz 以上,器件由感性转为容性,不再作为纯电感使用,需避免在自谐振点附近作为感性元件工作。

四、典型应用场景

  • 射频前端的阻抗匹配与窄带滤波(在 SRF 以下频段)
  • 高频信号路径中的阻抗调谐与谐振电路
  • EMI/噪声抑制(作为阻抗元件用于特定频段)
  • 尺寸受限的移动终端、无线模块、蓝牙/Wi‑Fi/蜂窝子模块等空间受限设备

五、封装与安装建议

  • 0201 超小封装对贴装工艺要求高,建议使用高精度贴装机与微细焊膏模板。
  • 采用与元件尺寸匹配的焊盘设计,避免过大焊盘导致焊料桥或焊接不良。
  • 推荐遵循通用无铅回流工艺(参考 IPC/JEDEC 指南),注意预热与保温段,峰值温度一般不超过无铅回流规范(请以 TDK 官方数据为准)。
  • 装配时避免在器件两端施加过大机械应力,焊接冷却后避免弯曲 PCB 边缘导致裂纹。

六、选型与使用注意事项

  • 由于 DCR 相对较高,若应用对直流损耗或热量敏感(如连续大电流),需重新评估或选择低 DCR 的型号。示例:在额定电流 100 mA 下,器件的直流功耗约 P = I^2·R = 0.01·2.35 ≈ 23.5 mW。
  • 高频应用时关注 Q 值和等效串联电阻随频率变化的影响,若目标频段接近 SRF,应避免在谐振附近工作。
  • 环境(温度、湿度)与 PCB 散热条件会影响电感的电气参数与长期可靠性,关键应用建议进行样件测试验证。

七、检验与储存

  • 建议到货后进行外观检验与抽样电感值、DCR、SRF 测试以验证一致性。
  • 储存时避免潮湿与强酸碱环境,长期储存建议遵循厂商的包装与防潮箱(或干燥剂)要求。

总结:MLG0603P56NJT000 以超小封装和较高自谐频率适合空间受限的射频与高频应用,但较高的 DCR 与有限的直流电流承载能力要求在选型和电路设计阶段充分考虑功耗与热管理。对于关键设计,请结合实际频段进行板级验证或咨询 TDK 官方技术资料。

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
