TDK MLG1005S68NJT000 贴片电感产品概述

MLG1005S68NJT000是TDK推出的0402封装(公制1005)多层片式电感,专为小型化、低功耗射频及电源电路设计,凭借稳定的电感特性、可控的损耗及紧凑尺寸,广泛适配消费电子、无线通信等领域的高密度布局需求。

一、核心基础规格参数

该电感的基础参数明确了其基本电气与物理属性,关键指标如下:

  • 电感值:68nH(毫微亨),属于射频电路常用小电感范畴,满足信号匹配、滤波等功能需求;
  • 精度:±5%,即电感值波动范围为64.6nH~71.4nH,覆盖大多数射频电路对精度的要求,无需额外校准;
  • 额定电流:200mA(毫安),指长期工作允许的最大直流电流,在此电流下电感值变化不超10%(行业常规标准),无过热损坏风险;
  • 直流电阻(DCR):870mΩ(毫欧),在0402封装中属于较低水平,可有效降低电路直流损耗,提升电池供电设备续航;
  • 封装:0402(英制,对应公制1005),尺寸仅1.0mm×0.5mm,适配智能手机、无线耳机等小型化产品的高密度PCB布局;
  • 品牌:TDK,全球知名元器件厂商,产品以稳定性、可靠性著称。

二、关键电气性能指标

电气性能直接决定应用场景,该电感核心性能如下:

  • 品质因数(Q值):8@100MHz,Q值为储能与损耗之比,越高损耗越低。在100MHz频段内Q值达8,可降低射频信号传输损耗,提升电路信号质量,适合射频匹配、滤波等对损耗敏感的应用;
  • 自谐振频率(SRF):800MHz,即电感与自身寄生电容谐振的频率。工作频率低于800MHz时呈感性,满足常规电感功能;高于800MHz时呈容性,可用于部分容性匹配场景。800MHz的SRF覆盖FM广播(88~108MHz)、蓝牙低功耗(BLE,2.4GHz以下部分频段)、4G LTE低频段(如700MHz)等常见场景。

三、封装与物理特性

0402封装的物理优势适配小型化设计需求:

  • 小型化布局:尺寸比0603封装小约60%,可显著节省PCB空间,满足智能手表、无线耳机等便携设备的高密度布局;
  • 可靠工艺:采用TDK多层陶瓷电感工艺,引脚与焊盘结合牢固,抗机械应力能力强,可承受回流焊、波峰焊等常规SMT工艺,长期使用无脱焊、开裂风险;
  • 环保合规:符合RoHS、REACH标准,无铅无镉,适配全球市场出口需求。

四、典型应用场景

结合参数特性,该电感主要应用于:

  1. 射频前端匹配:FM收音机、蓝牙低功耗模块(如智能手环无线通信)中,用于信号阻抗匹配,降低反射损耗,提升传输效率;
  2. 小电流电源滤波:可穿戴设备、蓝牙耳机的电池供电电路中,过滤高频噪声、稳定输出电压,870mΩ的DCR不显著增加功耗;
  3. 无线通信辅助电路:WiFi 2.4GHz频段的部分辅助电路(如低噪声放大器匹配)中,利用高于800MHz时的容性特性,满足特殊设计需求;
  4. 消费电子小型化产品:智能手机、智能手表、无线耳机等产品的PCB空间有限,0402封装可提升布局密度,同时保证性能稳定。

五、选型与使用注意事项

使用时需注意以下要点:

  • 电流限制:避免工作电流超200mA,否则可能导致电感值漂移、过热损坏;
  • 频率适配:需电感呈感性时,工作频率应低于800MHz;需容性时,可利用高于800MHz的特性,但需确认电路设计需求;
  • PCB布局:0402封装尺寸小,需优化焊盘设计与回流焊参数,避免虚焊;
  • 温度范围:常规工作温度为-40℃~125℃,避免长期超125℃使用。

综上,MLG1005S68NJT000凭借紧凑尺寸、稳定性能及低损耗特性,成为小型化射频与电源电路的高性价比选择,适配消费电子、无线通信等多领域需求。

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
